Description

Technical Field

[0001] This invention relates to the field of computer technology, and in particular to a method, apparatus, device, and medium for project context isolation in a multi-host environment. Background Technology

[0002] The Model Context Protocol (MCP) is an open protocol for exchanging tool definitions, resources, and context information between the client runtime environment and the backend service. It is widely used in intelligent coding assistants and AI (Artificial Intelligence) agent systems. The existing MCP architecture defines a three-layer structure of host, client, and server, supporting standard input / output, Hypertext Transfer Protocol (HTTP), and other transmission methods. Each host starts a backend process through a configuration file and exposes tools for client invocation. The adapter pattern, a common software engineering pattern, has been used to shield invocation differences between different environments; truncating large language model context characters or tokens, and limiting the depth and list length of nested structured data, are also common serialization security strategies.

[0003] In current technologies, all integrated environment windows share the same project identifier and the same data directory; protocol tool handlers directly instantiate the intelligent agent engine, coupling logic such as stage execution and health checks with specific host types; stage outputs from different workspace windows are written to the same persistent directory, with later writes overwriting earlier ones; context queries serialize the project context as is, potentially returning excessively large payloads and fields that should not be visible in the current window. However, existing technologies have the following drawbacks: fixed identifiers cause cross-session crosstalk, making workflows unreliable when multiple projects are running in parallel; a lack of protocol-independent abstract interfaces necessitates copying orchestration code for each new host, leading to version drift; full context queries pose leakage and performance risks; and the inability to securely serve multi-host concurrent sessions within the same deployment artifacts. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a method, apparatus, device, and medium for project context isolation in a multi-homed environment. This can solve the problems of data crosstalk, code redundancy, and read security faced by intelligent coding assistants when accessing multiple client environments in parallel by constructing a protocol-independent multi-homed adaptation framework and project context isolation mechanism. The specific solution is as follows: Firstly, this application discloses a project context isolation method in a multi-host environment, including: The protocol tool call request sent by the target host in a multi-host environment is received through a preset protocol-independent interface, and the host metadata in the protocol tool call request is identified. Then, the host metadata is parsed according to a preset priority order to obtain the project identifier corresponding to the protocol tool call request. The adapter instance cache is queried based on the project identifier. If a match is found, the corresponding core orchestration adapter instance is read from the adapter instance cache. If no match is found, the core orchestration adapter instance is created and written to the adapter instance cache. Determine the function type mapped to the protocol tool call request, and delegate the protocol tool call request to the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance through the target adapter corresponding to the target host; The target core orchestration adapter instance is executed, and the corresponding operation is performed according to the function type. The execution result is then returned to the target host. If the function type is a context snapshot construction function, the project context corresponding to the target data storage partition corresponding to the project identifier is read in read-only mode. The project context is recursively truncated based on a preset truncation parameter, and the truncation result is serialized. The serialized result, the project identifier, and the context snapshot corresponding to the preset truncation parameter are then fed back to the target host. The target data storage partition stores the project context corresponding to the project identifier in an isolated manner.

[0005] Optionally, the step of receiving the protocol tool invocation request sent by the target host in a multi-host environment through a preset protocol-independent interface, identifying the host metadata in the protocol tool invocation request, and then parsing the host metadata according to a preset priority order to obtain the project identifier corresponding to the protocol tool invocation request includes: The system receives protocol tool call requests sent by the target host in a multi-host environment through a preset protocol-independent interface, and analyzes the protocol tool call requests to determine the host type, the session identifier of the target host, and the corresponding project identifier. If the project identifier is not included in the protocol tool call request, then the project identifier is queried from the current environment variables; If the project identifier cannot be found in the current environment variables, then determine whether the host type belongs to the preset host type; If the host type belongs to a preset host type, the prefix corresponding to the host type is concatenated with the truncation result of the session identifier to obtain the project identifier corresponding to the protocol tool call request; the truncation result of the session identifier is a string obtained by truncating the session identifier according to a preset truncation length; If the host type does not belong to the preset host type, the current call is terminated and the corresponding call error information is returned.

[0006] Optionally, before querying the adapter instance cache based on the project identifier, and if a match is found, reading the corresponding core orchestration adapter instance from the adapter instance cache; and if a match is not found, creating the core orchestration adapter instance and writing it to the adapter instance cache, the method further includes: Perform character validity and length checks on the project identifier; If the item identifier contains a preset illegal character or the length of the item identifier exceeds a preset length threshold, the corresponding structured error code of the item identifier is returned.

[0007] Optionally, the step of querying the adapter instance cache based on the project identifier, and if a match is found, reading the corresponding core orchestration adapter instance from the adapter instance cache; if a match is not found, creating the core orchestration adapter instance and writing it to the adapter instance cache, includes: The adapter instance cache is queried using the project identifier as the key. If the query finds a match, the corresponding core orchestration adapter instance is read from the adapter instance cache. If no match is found, the core orchestration adapter instance is created and written to the adapter instance cache; the core orchestration adapter instance is bound to the target data storage partition corresponding to the project identifier.

[0008] Optionally, determining the function type mapped to the protocol tool invocation request and delegating the protocol tool invocation request to the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance through the target adapter corresponding to the target host includes: Construct a target adapter that corresponds to the host type in the host metadata; Determine the function type mapped to the protocol tool call request, and determine the target core orchestration adapter instance in the core orchestration adapter instance that corresponds to the function type; The context snapshot building function is mapped to the target core orchestration adapter instance for execution via the target adapter.

[0009] Optionally, the step of reading the project context corresponding to the target data storage partition corresponding to the project identifier in read-only mode, recursively truncating the project context based on a preset truncation parameter, serializing the obtained truncation result, and then feeding back the obtained serialization result, the project identifier, and the context snapshot corresponding to the preset truncation parameter to the target host includes: The project context corresponding to the target data storage partition corresponding to the project identifier is read in read-only mode, and the project context is recursively truncated based on the preset nesting depth limit, the preset single string length limit, and the preset single list element number limit to obtain the corresponding truncation result. The truncation result is serialized to obtain the corresponding serialization result; A context snapshot corresponding to the serialization result, the project identifier, and the preset truncation parameters is constructed, and the context snapshot is fed back to the target host; no data is written to the target data storage partition during the construction of the context snapshot.

[0010] Optionally, the project context isolation method in the multi-homed environment further includes: Before writing the project context or the context snapshot to the target data storage partition, read the encryption switch status; If the encryption switch is in the on state and a symmetric encryption key exists, then the serialized byte stream of the project context or the context snapshot is symmetrically encrypted, and the encrypted result is written to the target data storage partition. If the encryption switch is in the ON state and the symmetric encryption key is missing, the current write operation will be aborted and the corresponding key error message will be returned.

[0011] Secondly, this application discloses a project context isolation device in a multi-host environment, comprising: The metadata parsing module is used to receive protocol tool call requests sent by the target host in a multi-host environment through a preset protocol-independent interface, identify the host metadata in the protocol tool call request, and then parse the host metadata according to a preset priority order to obtain the project identifier corresponding to the protocol tool call request. The instance processing module is used to query the adapter instance cache based on the project identifier. If a match is found, the corresponding core orchestration adapter instance is read from the adapter instance cache. If no match is found, the core orchestration adapter instance is created and written to the adapter instance cache. The function mapping module is used to determine the function type mapped to the protocol tool call request, and to delegate the protocol tool call request to the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance through the target adapter corresponding to the target host; The execution result feedback module is used to execute the target core orchestration adapter instance, perform corresponding operations according to the function type, and return the execution result to the target host. Specifically, if the function type is a context snapshot construction function, the module reads the project context corresponding to the target data storage partition corresponding to the project identifier in read-only mode, recursively truncates the project context based on preset truncation parameters, serializes the truncation result, and then feeds back the serialized result, the project identifier, and the context snapshot corresponding to the preset truncation parameters to the target host. The target data storage partition stores the project context corresponding to the project identifier in isolated locations.

[0012] Thirdly, this application discloses an electronic device, including: Memory, used to store computer programs; A processor is used to execute the computer program to implement the project context isolation method in a multi-homed environment as described above.

[0013] Fourthly, this application discloses a computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the project context isolation method in a multi-homed environment as described above.

[0014] In this application, a protocol tool invocation request sent by a target host in a multi-homed environment can be received through a preset protocol-independent interface. The host metadata in the protocol tool invocation request is identified, and then parsed according to a preset priority order to obtain the project identifier corresponding to the protocol tool invocation request. Based on the project identifier, the adapter instance cache is queried. If a match is found, the corresponding core orchestration adapter instance is read from the adapter instance cache; if no match is found, the core orchestration adapter instance is created and written to the adapter instance cache. The function type mapped by the protocol tool invocation request is determined, and the protocol tool invocation request is delegated to the core orchestration adapter through the target adapter corresponding to the target host. The target core orchestration adapter instance corresponding to the function type is executed in the instance; the target core orchestration adapter instance is executed, the corresponding operation is performed according to the function type, and the execution result is returned to the target host; wherein, if the function type is the context snapshot construction function, the project context corresponding to the target data storage partition corresponding to the project identifier is read in read-only mode, the project context is recursively truncated based on the preset truncation parameter, and the obtained truncation result is serialized, and then the obtained serialization result, the project identifier, and the context snapshot corresponding to the preset truncation parameter are fed back to the target host; the target data storage partition stores the project context corresponding to the project identifier in isolation.

[0015] Therefore, the method of this application unifies the handling of protocol tool call requests from various hosts through a pre-defined protocol-independent interface, ensuring that all business tools in the protocol service rely solely on the interface and not on specific model context protocol transmission methods. Thus, when adding a new host type, only the corresponding thin-package adapter needs to be added according to the host type, keeping the protocol tool table unchanged and eliminating the need for orchestration logic such as execution and health checks for each host replication phase. Since core orchestration adapter instances are cached using the project identifier as the key, different sessions within the same process are bound to different core orchestration adapter instances, preventing cross-interference between multi-window parallel projects. Because the target adapter only performs single-line delegation and avoids repeated gating or skill scheduling, side effects of the same phase are consistent across different hosts, preventing drift during cross-host integration. The context snapshot construction function is executed in read-only mode, truncated in multiple dimensions, and returns truncation flags and budget metadata. Therefore, the response size of a single context query is controllable, preventing the leakage of fields that should not be seen by the current window and avoiding triggering phase write operations. In this way, the protocol tool layer is decoupled from the specific model context protocol transmission method, the protocol tool table is modified without modification when a new host is added, and the development efficiency of adding a new host is effectively improved; independent projects of different customers are processed in parallel within the same process without crosstalk, and the expected crosstalk event of multi-window context is close to zero; context query is a bounded read-only query; and all capabilities return statistics through the same interface, effectively improving field consistency.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Existing technologies have the following drawbacks: fixed identifiers cause cross-session interference, making workflows unreliable when multiple projects are running in parallel; they lack protocol-independent abstract interfaces, requiring code copying for each new host, leading to version drift; full context queries pose leakage and performance risks; and they cannot securely serve multi-host concurrent sessions within the same deployment artifact.

[0020] To overcome the aforementioned technical problems, this application discloses a project context isolation method, apparatus, device, and medium in a multi-homed environment. By constructing a protocol-independent multi-homed adaptation framework and project context isolation mechanism, the problems of data crosstalk, code redundancy, and reading security faced by intelligent coding assistants when accessing multiple client environments in parallel can be solved.

[0021] See Figure 1 As shown in the figure, this invention discloses a project context isolation method in a multi-host environment, including: Step S11: Receive the protocol tool call request sent by the target host in the multi-host environment through a preset protocol-independent interface, identify the host metadata in the protocol tool call request, and then parse the host metadata according to a preset priority order to obtain the project identifier corresponding to the protocol tool call request.

[0022] In this embodiment, the first step is to receive the protocol tool invocation request sent by the target host in a multi-hosted environment through a preset protocol-independent interface, and then analyze the protocol tool invocation request to determine the host type, the target host's session identifier, and the corresponding project identifier. It should be noted that, as... Figure 2As shown, the pre-defined protocol-independent interface, also known as the host adapter abstract interface, is used to shield the differences between different clients and provide five unified capabilities: stage execution, stage list query, health check, context snapshot construction, and local deliverable list query. This allows all business tools in the protocol service to call only this interface instance without depending on the specific model context protocol transmission method. The host environment refers to the client environment running the intelligent coding assistant or intelligent agent. Host types are categorized by client environment type, including graphical integration environments, command-line integration environments, pre-defined coding assistant types, and browser environments. The session identifier is a unique identifier for the target host's current session in the host metadata. This classification is based on the interaction method between the host and the model context protocol service and the project identifier derivation capability. The model context protocol refers to the open protocol for exchanging tool definitions, resources, and context information between the client runtime environment and the backend service.

[0023] It should be noted that the preset priority order is that explicit call parameters take precedence over environment variables, and environment variables take precedence over automatic derivation based on host type and session identifier, also known as three-level item identifier resolution. Therefore, based on the preset priority order, the following processing is performed: If the protocol tool call request does not contain the item identifier, the item identifier is queried from the current environment variables. If the item identifier is not found in the current environment variables, it is determined whether the host type belongs to a preset host type. If the host type belongs to a preset host type, the prefix corresponding to the host type and the truncation result of the session identifier are concatenated to obtain the item identifier corresponding to the protocol tool call request; the truncation result of the session identifier is the string obtained after truncating the session identifier according to a preset truncation length. If the host type does not belong to a preset host type, the current call is terminated and the corresponding call error information is returned. Here, the item identifier is a unique identifier that distinguishes the data boundaries of different business items and corresponds to an independent data storage partition.

[0024] Specifically, such as Figure 3 As shown, explicit parameters in tool calls take precedence. If the caller has explicitly passed the project identifier in the protocol tool call request, and the project identifier parameter is not empty and valid, then this explicit parameter is directly used as the final project identifier, and subsequent derivation is not performed. If the protocol tool call request does not contain the project identifier, then the explicit configuration in the current environment variable is read, and if the environment variable is not empty, it returns immediately. For example, when the continuous integration pipeline of the command-line integration environment sets the explicit project identifier to "ci_demo_project" through the environment variable and session identifier metadata also exists, the three-level priority determination hits the explicit environment variable in the second step, skips the session derivation, and the core orchestration adapter always reads and writes the "ci_demo_project" directory, realizing repeated builds and demonstrations using a fixed identifier, and preventing data directory drift due to session changes.

[0025] Specifically, the default host type is a predefined encoding assistant type, which is a host type whose host metadata carries a session identifier field that can be used to deduce the project identifier according to predefined rules.

[0026] Furthermore, the graphical integrated environment and the command-line integrated environment adopt symmetrical derivation rules and use different project identifier prefixes respectively; the preset truncation length limit is 48 characters, and the concatenation rules meet the requirements. Where L is the preset cut-off length, and L is no greater than 48. Indicates a prefix, Host type, Indicates truncation. This serves as a session identifier. For example, a user simultaneously opens two workspaces, Client A and Client B, in a graphical integrated environment. Each workspace launches an independent protocol client, and neither explicitly sets a project identifier. The two clients carry different session identifiers. The host routing module derives two different project identifiers for each: "graphical prefix combined with session A truncation" and "graphical prefix combined with session B truncation." The adapter cache is bound to two core orchestration adapter instances, and the data storage directory partitions do not overwrite each other. Client A's requirement mining output will not be read by Client B's window. The core orchestration adapter packages the intelligent agent engine and chain of responsibility router as the default implementation of the host adapter interface, carrying all business orchestration logic.

[0027] Furthermore, for single-project hosts, such as the default core host, if an explicit project identifier is not configured, the host type is not specified, and the caller does not pass a project identifier parameter, the level 3 priority determination fails. This method terminates the call and returns a clear error message, requiring an explicit project identifier and not creating an adapter instance. This avoids silently writing the default directory on production hosts where the session cannot be inferred, preventing misuse of multi-tenant services. By using a three-level priority system, a unique project identifier is assigned to each session to achieve identity isolation.

[0028] In this way, because the three-level priority determination establishes a definite order for explicit parameters, environment variables, and session inference, the same project identifier remains constant in explicit configuration scenarios and is automatically inferred by session in predefined coding assistant types. This satisfies both the repeatable build requirements of continuous integration pipelines and the multi-window parallel isolation requirements of graphical environments. Since fast failure occurs when inference fails, there will be no silent rollback to the default identifier. Furthermore, the fast failure when inference fails in the three-level resolution and the read-only disk of bounded snapshots are prerequisites for each other. Both must be enabled simultaneously to achieve multi-window isolation, thus compensating for the deficiency of the model context protocol's protocol layer in not guaranteeing session isolation from the implementation layer.

[0029] It should be noted that before querying the adapter instance cache based on the project identifier, the project identifier needs to be validated. This includes character validity and length validation. If the project identifier contains preset illegal characters or its length exceeds a preset length threshold, a corresponding structured error code is returned. Specifically, regardless of whether the project identifier is obtained through explicit parameters, environment variables, or session deduction, character validity and length validation must be performed before creating the core orchestration adapter instance. Preset illegal characters include path separators, spaces, and other characters that may disrupt the directory structure or cause out-of-bounds writes. If validation fails, the host routing module refuses to create the adapter instance and returns the corresponding structured error code for the project identifier, such as a structured error object containing the error category and the original value of the project identifier, for the host machine to process in a machine-resolvable manner. After successful validation, the instance cache query process then proceeds.

[0030] In this way, because illegal or excessively long project identifiers are rejected before entering the adapter instance cache and persistence, out-of-bounds writes, multi-project data concatenation, or creation failures will not occur in the persistent directory, and the isolation mechanism itself will not become a source of failure. Since structured error codes are returned, the host machine and operations personnel can directly pinpoint the source of illegal input. Therefore, the storage path always consists of valid and length-constrained project identifiers, and validation failures are observable and auditable.

[0031] Step S12: Query the adapter instance cache based on the project identifier. If a match is found, read the corresponding core orchestration adapter instance from the adapter instance cache. If a match is not found, create the core orchestration adapter instance and write it to the adapter instance cache.

[0032] In this embodiment, it is necessary to query the adapter instance cache based on the project identifier. Specifically, the adapter instance cache is queried using the project identifier as the key. If the query matches, the corresponding core orchestration adapter instance is read from the adapter instance cache; if the query does not match, a core orchestration adapter instance is created and written to the adapter instance cache. The core orchestration adapter instance is bound to the target data storage partition corresponding to the project identifier. Specifically, the adapter instance cache is a memory-level cache, and its key is the parsed final project identifier. When a query matches, the existing core orchestration adapter instance is directly reused, avoiding the redundant construction of the intelligent agent engine and chain of responsibility router. The core orchestration adapter instance is lazy-created, meaning it is created only when a project identifier first appears. The created instance is bound to the target data storage partition corresponding to the project identifier, and the cache key corresponds to the directory partition, eliminating cross-identifier crosstalk. Instances can be rebuilt during explicit initialization; test hooks can clear the cache for testing purposes.

[0033] In this way, since core orchestration adapter instances and target data storage partitions are bound to the same project identifier, reads and writes of any core orchestration adapter instance fall within its own target data storage partition, and stage outputs of multi-window parallel projects do not overwrite each other. Because instances are cached and reused, subsequent calls to the same project avoid the overhead of repeated construction, achieving single-instance maintenance of the core engine. Therefore, the principle of "last write does not overwrite first write" applies, with stage outputs from different workspace windows written to their respective target data storage partitions; instance caching and reuse reduce construction overhead; health checks can return project identifiers, stage, and skill statistics for each instance, enabling fault location by session in multi-host deployments, distinguishing between internal engine faults and specific host session configuration errors. Independent adapter instances are cached by project identifier and mapped to independent target data storage partitions. When writing to disk, file paths for different project identifiers are naturally partitioned, without overwriting each other, achieving storage isolation.

[0034] Step S13: Determine the function type mapped by the protocol tool call request, and delegate the protocol tool call request to the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance through the target adapter corresponding to the target host.

[0035] In this embodiment, based on the function type mapped by the protocol tool call request, the protocol tool call request needs to be delegated to the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance through the target adapter corresponding to the target host. This requires constructing a target adapter corresponding to the host type in the host metadata; determining the function type mapped by the protocol tool call request and identifying the target core orchestration adapter instance corresponding to the function type in the core orchestration adapter instance; and mapping the context snapshot building function to the target core orchestration adapter instance for execution through the target adapter.

[0036] Specifically, the target adapter, also known as the thin-package adapter, provides a lightweight layer for different host types, such as graphical integration environments and command-line integration environments. This lightweight layer is only responsible for project identifier deduction and host metadata annotation. For example, it calls the project identifier deduction function during the initialization phase and merges session dimension fields such as host type and final project identifier in the health check results. The command-line variant can also attach large language model integration prompts. The function type corresponds to the five capabilities mentioned above: stage execution function, stage list query function, health check function, context snapshot construction function, and local deliverable list query function. The target core orchestration adapter instance corresponding to each function type in the core orchestration adapter instance is the execution unit that carries the corresponding business orchestration logic. The five types of public method bodies of the target adapter are all single-line delegations to the corresponding methods of the internal core orchestration adapter, without introducing gating, skill scheduling, or context merging logic into the thin-package layer. For other function types such as stage execution, stage list query, health check, and local deliverable list query, they are also single-line delegated by the target adapter to the target core orchestration adapter instance corresponding to the corresponding function type for execution. Among them, the thin-package adapter is a lightweight layer for specific host types, which is only responsible for project identifier derivation and host metadata annotation, while business logic is delegated to the core orchestration adapter.

[0037] In this way, due to the zero logical delegation of the thin wrapper layer, the stage side effects, stage completion flags, and error codes are completely consistent across hosts. The graphical and command-line environments will not generate different stage completion flags or error codes for the same project identifier. Since adding a new host only adds a thin wrapper class without modifying the protocol tool table, the cost of adding a new host is significantly reduced, and the protocol tool table is modified zero when a new host is added. Therefore, cross-host behavior is consistent, cross-host integration is regressible, the protocol tool table is modified zero when a new host is added, and health check results can carry session dimension fields such as host type and final project identifier, facilitating fault location by operations and maintenance.

[0038] Step S14: Execute the target core orchestration adapter instance, perform the corresponding operation according to the function type, and return the execution result to the target host; wherein, if the function type is the context snapshot construction function, the project context corresponding to the target data storage partition corresponding to the project identifier is read in read-only mode, the project context is recursively truncated based on the preset truncation parameter, and the obtained truncation result is serialized, and then the obtained serialization result, the project identifier, and the context snapshot corresponding to the preset truncation parameter are fed back to the target host; the target data storage partition stores the project context corresponding to the project identifier in isolation.

[0039] In this embodiment, the target core orchestration adapter instance needs to be executed, and corresponding operations need to be performed according to the function type. The execution result is then returned to the target host. Taking the context snapshot build function as an example, the project context corresponding to the target data storage partition corresponding to the project identifier needs to be read in read-only mode. The project context is then recursively truncated based on a preset nesting depth limit, a preset single string length limit, and a preset single list element count limit to obtain the corresponding truncation result. Specifically, as shown... Figure 4 As shown, the snapshot construction reads the complete context dictionary corresponding to the current stage and reads it from the loaded memory. If the disk file is encrypted, it is read directly without going through the disk encryption. Then, preset truncation parameters are applied recursively. The relationship between the truncation parameters satisfies d≤4, |string|≤2000, |list|≤50, that is, the preset nesting depth is capped at 4 levels, the preset single string length is capped at 2000 characters, and the preset single list element count is capped at 50 items. The above values ​​are for the example and can be overridden by environment variables, but they do not change the two-level structure of recursive truncation combined with the total budget. Types that cannot be serialized are also subject to the preset single string length limit after being converted to strings. Malicious over-budgets will be forcibly limited to the system limit. Diagnostic fields, such as gating failure diagnostic fields, can be optionally retained with priority.

[0040] Furthermore, the truncated result needs to be serialized to obtain the corresponding serialized result. Specifically, the length of the serialized result is constrained by the character budget, satisfying... Where B is the character budget, with a default value of 12000, which can be overridden by tool calls; if the serialized length exceeds the character budget, the truncation flag is set to true, and the returned object contains only the project identifier, the current stage, the truncation flag being true, the character budget field, and the serialization result prefix, without the complete context key, thus preventing the host from mistakenly treating the preview as the full state.

[0041] Finally, as Figure 5As shown, a context snapshot corresponding to the serialization result, project identifier, and preset truncation parameters needs to be constructed and fed back to the target host. No data is written to the target data storage partition during the construction of the context snapshot. Specifically, the context snapshot is a read-only view; the construction process does not call stage execution, trigger skill-based language model calls, or write to disk. Stage execution still requires a separate stage execution tool and explicit passing of the stage identifier. For example, if the project context contains the complete requirements document text, the quotation module list, and the audit scan details, and the serialized length significantly exceeds 12,000 characters, and the snapshot module still exceeds the budget after recursive truncation, it returns a truncation flag of true, a character budget of 12,000, and a preview prefix. The host interface can then prompt "Context has been truncated; please narrow your query scope or query in stages" to avoid host lag caused by excessively large single protocol responses. For example, when the main chain workflow fails to pass gating and the project context has been written to structured failure diagnostic fields, such as a list of missing keys, the host calls the context query tool. The snapshot module reads the memory context, including the diagnostic fields, truncates it, and returns it without triggering a stage write operation. The host can then display machine-resolvable failure reasons without re-executing the stage, forming an upstream-downstream collaboration with the main chain's gating diagnostics. Another example is when third-party plugin developers assume that the object returned by the context query tool can be directly written back as stage input. Because the snapshot interface's documentation semantics are read-only, and the implementation path does not call stage execution or write to disk, the probability of read-only queries being misused as write paths is significantly reduced. This separation of responsibilities from the stage execution tool achieves behavioral isolation. Furthermore, when the snapshot returns, it only returns the context corresponding to the current project identifier, and it is truncated to prevent sensitive fields from project A from being mixed into the return results of project B, thus achieving result isolation.

[0042] In this way, by employing multi-dimensional truncation based on depth, string length, list capacity, and total character budget instead of a single dimension, the size of a single snapshot response can be controlled regardless of the depth of the project context nesting, the length of the string, or the size of the list, avoiding host lag caused by excessively large single protocol responses. Because truncation flags and budget metadata are returned, the caller can know whether truncation has occurred, preventing the preview from being mistaken for the full context. Since it is read-only and does not write to disk or trigger large language model calls, context queries have no side effects. It is expected that snapshot build time will be effectively shortened under truncation parameters of depth 4, string length 2000, list capacity 50, and total budget 12000. Therefore, the size of a single snapshot response is effectively reduced under the default budget; the truncation flag trigger rate is observable during very large context queries; the separation of read-only queries and stage execution tools significantly reduces the probability of third-party plugins mistakenly treating snapshots as writable full contexts; and the host can display diagnostic reasons without re-executing stages when gating fails.

[0043] It should be noted that, based on the aforementioned embodiments, optional symmetric encryption is added before writing the project context or context snapshot to the target data storage partition. Specifically, before writing the project context or context snapshot to the target data storage partition, the encryption switch status is read. If the encryption switch is enabled and a symmetric encryption key exists, the serialized byte stream of the project context or context snapshot is symmetrically encrypted, and the encrypted result is written to the target data storage partition. If the encryption switch is enabled and a symmetric encryption key is missing, the writing operation is aborted, and a corresponding key error message is returned. Specifically, the encryption switch is controlled by environment variables and can be enabled for both the global context file and the context snapshot file using the same policy. This encryption module is a means to enhance project isolation rather than an independent function; it is orthogonal to gating orchestration and snapshot construction, and does not change the combined architecture of thin wrapper plus core orchestration or the working logic of three-level project identifier resolution. Encrypted writing satisfies symmetric encryption of the serialized byte stream, and the first byte of the ciphertext is not equal to the starting character of the structured object. Reading follows a heuristic branching mechanism based on the first byte: if the first byte is the starting character of the structured object, plaintext parsing is performed; otherwise, decryption is performed, thus ensuring automatic compatibility with historical plaintext files. Distinguishing errors are returned for both plaintext parsing and decryption failures. The snapshot module builds snapshots from already loaded memory and does not directly read ciphertext files; the gating module is also read-only from memory. For example, in a production environment with encryption enabled and the global context file encrypted, the snapshot module in the main chain stage writes to the snapshot file after the requirements document gating passes. The snapshot file calls the same encrypted writing module as the global context, and a rollback request triggers decryption loading. After rollback, the memory state is consistent with the snapshot time, satisfying both disk unreadableness and phased recovery compliance. Furthermore, fast failure occurs when encryption is enabled but the symmetric encryption key is missing, prohibiting rollback to plaintext writing.

[0044] In this way, because the encryption switch and symmetric encryption key are used together for determination, the write abort rate is effectively improved when encryption is enabled but the key is missing, and there are no plaintext write errors. Since reading is heuristically branched based on the first byte, the same read path is compatible with both historical plaintext files and new ciphertext files, and encryption capabilities are optional enhancements without damaging existing data. Because encryption, gating orchestration, and snapshot construction are orthogonal, the development environment maintains plaintext for easy debugging, while the production environment enables encryption on a project-by-project basis, allowing for granular control. Therefore, static encryption at the project data directory level can be switched on and off for each project, and the encryption granularity for sensitive production projects and test projects is controllable, avoiding the equal exposure of sensitive projects when global disk encryption is disabled for troubleshooting.

[0045] In this embodiment, a pre-defined protocol-independent interface is used to uniformly accept protocol tool call requests from various hosts. This ensures that all business tools in the protocol service rely solely on this interface and not on specific model context protocol transmission methods. Therefore, when adding a new host type, only the corresponding thin-package adapter needs to be added according to the host type, and the protocol tool table remains unchanged. There is no need for orchestration logic such as execution and health checks for each host replication phase. Since the core orchestration adapter instance is cached using the project identifier as the key, different sessions within the same process are bound to different core orchestration adapter instances, so multi-window parallel projects do not interfere with each other. Since the target adapter only performs single-line delegation and does not repeat gating or skill scheduling, the side effects of the same phase are consistent on different hosts, and cross-host joint debugging does not drift. The context snapshot construction function is executed in read-only mode, truncated in multiple dimensions, and returns truncation flags and budget metadata. Therefore, the response size of a single context query is controllable, and fields that should not be seen by the current window will not be leaked, nor will phase write operations be triggered. In this way, the protocol tool layer is decoupled from the specific model context protocol transmission method, the protocol tool table is modified without modification when a new host is added, and the development efficiency of adding a new host is effectively improved; independent projects of different customers can be processed in parallel within the same process without crosstalk, and the expected crosstalk event of multi-window context is close to zero; context query is a bounded read-only query, with no disk write side effects and no triggering of large language model calls; and all capabilities are returned and statistically analyzed through the same interface, effectively improving field consistency.

[0046] As a preferred embodiment, such as Figure 6 The diagram illustrates the overall framework of the multi-host adaptation system corresponding to the project context isolation method in the multi-host environment of this application. This overall framework includes: a host environment layer 101, a protocol service module 102, an adapter layer 103, a core orchestration adapter 105, an intelligent agent engine 106, and project identifier-isolated storage 107, where project identifier-isolated storage is also known as data storage partitioning. The host environment layer 101 includes various host types, such as a graphical integrated environment 101a and a command-line integrated environment 101b. Each host communicates with the protocol service module 102 through a model context protocol.

[0047] Taking a specific implementation scenario as an example, a user simultaneously opens two workspace windows within the same graphical integration environment, corresponding to Client A's e-commerce order management system development project and Client B's enterprise customer relationship management system development project, respectively. Each workspace window launches an independent Model Context Protocol (MTP) client, and neither explicitly configures a project identifier.

[0048] Protocol tool call request reception and metadata identification. The protocol service module 102 receives protocol tool call requests from the graphical integration environment 101a through the business tool layer 102a. For example, performing a requirements mining phase or querying the current project context snapshot. The protocol service module 102 identifies the host metadata carried in the request, including the host type (graphical integration environment) and the current session identifier (such as the folder path or session identifier corresponding to the workspace window).

[0049] Level 3 Project Identifier Resolution. Adapter Router 102b parses the host metadata according to a preset priority order: First, it checks whether the protocol tool call request contains an explicit project_id parameter; second, it checks whether project_id is configured in the environment variables; finally, since the host type is a session-inferable graphical integrated environment, Adapter Router 102b reads the metadata of the current session, concatenates a graphical-specific prefix, and performs secure truncation on the concatenated string to generate independent project identifiers for the two workspace windows.

[0050] Adapter instance cache lookup and creation. Adapter route 102b queries the adapter instance cache based on the parsed project identifier. For customer A's project identifier, if the corresponding core orchestration adapter instance is not found in the cache, a new core orchestration adapter instance is created and written to the cache; for customer B's project identifier, a separate core orchestration adapter instance is also created and cached. The two workspace windows thus obtain their own independent core orchestration adapter instances, which are then bound to separate project identifier-isolated storage 107.

[0051] Function type mapping and delegated execution. Adapter layer 103 determines the function type mapped to the protocol tool call request (such as "stage execution" or "context snapshot build"), and delegates the request to the target core orchestration adapter instance of the corresponding function type in core orchestration adapter 105 through the thin-package adapters corresponding to the target host (graphical thin-package 104a and command-line thin-package 104b). Specifically, for the graphical integration environment 101a, graphical thin-package adapter 104a can be called; for the command-line integration environment 101b, command-line thin-package adapter 104b can be called. Taking the client A window requesting "context snapshot build" as an example, graphical thin-package 104a is only responsible for delegating the request line by line to core orchestration adapter 105, without repeating the gating or context merging logic in the thin-package layer.

[0052] The core orchestration adapter performs the execution and returns the results. Core orchestration adapter 105 performs the corresponding operation based on the function type. If it is a context snapshot construction function, core orchestration adapter 105 reads the project context in the target data storage partition corresponding to the project identifier in read-only mode, without triggering large language model calls or performing disk writes. Subsequently, core orchestration adapter 105 recursively truncates the project context according to preset truncation parameters, with a maximum depth of 4 levels, a maximum single string length of 2000 characters, and a maximum single list element count of 50 items. The truncation result is then serialized. If the total number of characters after serialization exceeds the preset character budget (default 12000 characters), the truncation flag is returned as true, along with the character budget value and a prefix of the serialization result; the complete context object is not returned. Finally, core orchestration adapter 105 returns the serialization result, project identifier, and truncation metadata to the corresponding client window in the graphical integration environment 101a through the graphical thin wrapper 104a and the protocol service module 102. The request processing flow of client B's window is exactly the same, but the data storage partitions operated on are independent.
