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.

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)

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"
    }
