AI Technical Summary

Technical Problem

In existing technologies, when Large Language Models (LLMs) interact with external services, there are risks such as ambiguous responsibilities, generalized permissions, misaligned billing, and compliance issues, making it impossible to achieve trustworthy interaction involving multiple organizations.

Method used

A blockchain-based multi-party collaborative MCP registration, authorization, and execution method is adopted. The blockchain smart contract coordinates the LLM provider, MCP provider, and end user, and uses an oracle as a trusted off-chain agent to realize the three-party interaction. The dual-signature mechanism and smart contracts are used for identity verification, permission management, and fee settlement.

Benefits of technology

It achieves precise definition of responsible parties, differentiated configuration of permission policies, accurate billing settlement, and compliance traceability, meeting regulatory requirements and providing a decentralized and trustworthy MCP invocation framework.

Abstract

The application provides a kind of multi-agent collaborative MCP registration, authorization and execution method based on blockchain, it is related to artificial intelligence technical field, including MCP provider, LLM provider, terminal user three parties, the registration, joint authorization and trusted execution of MCP are realized through smart contract, including: registration MCP metadata chain, apply for authorization for user-LLM combination, LLM initiates double signature call, contract verification and triggers execution, Oracle returns result and updates state.The application realizes decentralization, multi-agent collaboration, MCP call full-link verifiable, accurate definition of rights and responsibilities, supports fine-grained permission management and automatic fee settlement, meets GDPR, HIPAA and other compliance regulatory requirements, provides underlying support for large-scale and secure invocation of external services, and is suitable for SaaS, API market and other multi-scene applications.
