Agent Passport System -- MCP Server

Enforcement and accountability layer for AI agents. Bring your own identity. 20 essential tools by default: identity, delegation, enforcement, commerce, reputation.

APS_PROFILE=essential npx agent-passport-system-mcp

essential is the default profile — the 20 tools 90% of integrations need. Set APS_PROFILE=full for all 150 tools.

Available profiles: essential (default), identity, governance, coordination, commerce, data, gateway, comms, minimal, full.

For AI agents: visit aeoess.com/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 under APS_PROFILE=full: 150 tools across the protocol surface, including Wave 1 accountability primitives (Ed25519 ActionReceipt, AuthorityBoundaryReceipt, CustodyReceipt, ContestabilityReceipt, APSBundle, RFC 8785 JCS canonicalized and byte-match across implementations). Independently cited by PDR in Production (Nanook & Gerundium, UBC).

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.

Manual config (if setup doesn't detect your 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"
    }
  }
}
