Agent Passport System -- MCP Server
Enforcement and accountability layer for AI agents. Bring your own identity. 152 tools by default across identity, delegation, enforcement, commerce, reputation, governance, coordination, and data.
agent-passport-system-mcp 6.0.0 targets SDK 6.0.0; 5.0.2 targets SDK 5.x.
The default profile is full, all 152 tools. Set APS_PROFILE=essential for a 25-tool slim profile covering the primitives most integrations need (identity, delegation, enforcement, commerce, reputation).
Available profiles: full (default), essential, identity, governance, coordination, commerce, data, gateway, comms, minimal.
For AI agents: visit agent-passport.org/llms.txt for machine-readable documentation or llms-full.txt for the complete technical reference. MCP discovery: .well-known/mcp.json.
Works with any MCP client: Claude Desktop, Claude Code, Cursor, Windsurf, and more. Full surface area (the default): 152 tools across the protocol surface, including Wave 1 accountability primitives (Ed25519 ActionReceipt, AuthorityBoundaryReceipt, CustodyReceipt, ContestabilityReceipt, APSBundle, strict RFC 8785 JCS for interop-facing receipts, byte-match across implementations). Independently cited by PDR in Production preprint (Nanook & Gerundium).
Quick Start
Fastest: Remote (no install needed)
Connects via SSE to mcp.aeoess.com/sse. Zero dependencies. Restart your AI client.
Local install
Auto-configures Claude Desktop and Cursor. Restart your AI client.
Manual config (if setup doesn't detect your client)
Add to your MCP config file:
