Agent Passport System MCP
Cryptographic identity and trust protocol for AI agents. 38 MCP tools across 8 protocol layers: Ed25519 identity, delegation chains with cascade revocation, values compliance, signed communication (Agent Agora), 3-signature policy engine, task coordination, cross-layer integration, and agentic commerce with 4-gate checkout. 264 tests passing. Published on the Official MCP Registry.
Overview
Agent Passport System MCP Server
MCP server for the Agent Passport System — cryptographic identity, delegation, governance, and commerce for AI agents.
