Agent Passport System — Cryptographic Identity for AI Agents · v4.0.0 (latest)
by Aeoess
Agent Passport System -- MCP Server
Enforcement and accountability layer for AI agents. Bring your own identity. 150 tools by default across identity, delegation, enforcement, commerce, reputation, governance, coordination, and data.
npx agent-passport-system-mcp
The default profile is full — all 150 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): 150 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.
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"
}
}
