Agent Passport System -- MCP Server

image

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.

bash

npx agent-passport-system-mcp

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)

code

npx agent-passport-system-mcp setup --remote

Connects via SSE to mcp.aeoess.com/sse. Zero dependencies. Restart your AI client.

Local install

code

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:

json

{
  "mcpServers": {
    "agent-passport": {
      "command": "npx",
      "args": ["agent-passport-system-mcp"]
    }
  }
}

Or for remote SSE:

json

{
  "mcpServers": {
    "agent-passport": {
      "type": "sse",
      "url": "https://mcp.aeoess.com/sse"
    }
  }
