Verification Protocol
Understanding how delegation credentials are verified and validated in MCP-I
Verification Foundation
The Verification Protocol is a critical security component of MCP-I, defining standardized processes to cryptographically validate agent identity and delegation authority.
Verification Protocol
The MCP-I Verification Protocol defines how agents and services establish trust through cryptographic verification of identity and delegation credentials. This section covers the complete verification process from initial handshake to credential validation.
Key Topics
- Introduction - Core concepts and components of the verification protocol
- Verification Flows - Different verification patterns for various conformance levels
- MCP-I Handshake - Protocol for establishing secure identity exchanges
- Credential Verification - Methods for validating credential authenticity and integrity
- Delegation Validation - Checking scope and constraints in delegation credentials
- Revocation - Managing and checking credential revocation status
- Implementation Considerations - Error handling, optimization, and security best practices
- Verification Protocol Registry - Registry of approved verification methods and algorithms
Verification Architecture
The verification protocol is designed to be flexible across different MCP-I conformance levels while maintaining high security standards. The foundation of the protocol relies on:
- Decentralized identifiers (DIDs) for agent and service identity
- Verifiable credentials for delegation proof
- Cryptographic challenge-response mechanisms to verify live possession of keys
- Standardized scope and constraint validation patterns
Security Boundary
The verification process establishes the security boundary for MCP-I. Any compromise of the verification components can undermine the entire system's security.
