Agent Passport System -- MCP Server
Enforcement and accountability layer for AI agents. Bring your own identity. 154 tools by default across identity, delegation, enforcement, commerce, reputation, governance, coordination, and data.
npx agent-passport-system-mcp
agent-passport-system-mcp 8.1.0, 8.0.0 and 7.0.0 target SDK 8.x. The 6.x line targets SDK 6.x, and 5.0.2 targets SDK 5.x.
The default profile is full, all 154 tools. Set APS_PROFILE=essential for a 28-tool slim profile covering the primitives most integrations need (identity, delegation, enforcement, commerce, reputation). The count is what tools/list returns and includes list_profiles, which every profile exposes.
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): 154 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)
npx agent-passport-system-mcp setup --remote
Connects via SSE to mcp.aeoess.com/sse. Zero dependencies. Restart your AI client.
Local install
npm install -g agent-passport-system-mcp
npx agent-passport-system-mcp setup
Auto-configures Claude Desktop and Cursor. Restart your AI client.
Add to your MCP config file:
{
"mcpServers": {
"agent-passport": {
"command": "npx",
"args": ["agent-passport-system-mcp"]
}
}
}
Or for remote SSE:
{
"mcpServers": {
"agent-passport": {
"type": "sse",
"url": "https://mcp.aeoess.com/sse"
}
}
}
Tools (154)
Every tool carries MCP annotations. Read-only means the tool writes no file, calls no mutating remote endpoint and changes no session state other tools read. Destructive means it deletes, revokes, supersedes, overwrites or irreversibly consumes something. Network means it can contact an external host (see Network and local files). The hint values live in src/toolAnnotations.ts.
Meta: 2 tools
Identity and key rotation: 15 tools
Delegation and escalation: 10 tools
Principal identity: 6 tools
Reputation-gated authority: 7 tools
Coordination and provisional statements: 15 tools
Agora and agent messaging: 10 tools
Governance, charters, provenance, attribution: 40 tools
Commerce: 3 tools
Data governance: 20 tools
Gateway (removed in v3.0.0, stubs return a migration notice): 4 tools
Intent Network: 5 tools
Time and reserve attestation: 4 tools
Attribution weights: 2 tools
Attribution settlement: 3 tools
Capability token v0.1: 4 tools
Mutual authentication: 4 tools
Network and local files
The server makes outbound requests only from the tools below. Every other tool works offline. The Network column in the tables above marks the same set.
gateway.aeoess.com and aeoess.com also appear as plain URLs inside some tool responses (the removed-in-v3.0.0 stubs and the latest.json the Agora writes). The server does not fetch them. npx agent-passport-system-mcp setup --remote writes https://mcp.aeoess.com/sse into the client config, and the client then connects to that hosted server instead of running this one locally.
Local files the server reads or writes, all under the user's home directory unless overridden:
Keys are never written to disk by the server. identify holds the agent key pair in process memory for the session, and AGENT_KEY / AGENT_PRIVATE_KEY supply it from the environment. generate_keys, issue_passport and rotate_key return private keys in the tool response, and generate_keys and issue_passport redact them when the server runs in remote mode. create_principal keeps the principal key in memory and returns the full private key once on a local (stdio) server, redacted in remote mode as in generate_keys. It refuses to replace an existing principal unless called with replace=true. Many signing tools take a private key as an argument and use it for that call only. Session state (delegations, endorsements, charters, intents) lives in memory and is lost on restart.
Architecture
Layer 8: Agentic Commerce (primitives only; the preflight orchestration lives outside this server)
Layer 7: Integration Wiring (cross-layer bridges)
Layer 6: Coordination Protocol (task lifecycle)
Layer 5: Intent Architecture (policy engine, 3-signature chain)
Layer 4: Agent Agora (signed communication)
Layer 3: Beneficiary Attribution (Merkle proofs)
Layer 2: Human Values Floor (8 principles)
Layer 1: Agent Passport Protocol (Ed25519 identity)
