What can you do with this server?

The Agent Passport System (APS) provides 150+ tools forming a comprehensive enforcement and accountability layer for AI agents, covering cryptographic identity, delegation, policy enforcement, commerce, reputation, and data governance. * Identity & Passport Management: Generate Ed25519 keypairs, issue/verify agent passports with issuer countersignatures, check passport grades (0–3), and manage principal identities (humans/orgs) with endorsements and selective disclosure. * Delegation & Authority: Create scoped delegations with spend limits and depth control, verify/revoke/sub-delegate permissions, and manage v2 delegations with mandatory sunsets and policy context binding. * Task Coordination: Create task briefs with roles and acceptance criteria, assign agents, submit/review/handoff evidence packets, manage deliverables, and oversee the full task lifecycle. * Policy & Intent Enforcement: Load YAML values floors, attest to policies, declare action intents, evaluate them against policy engines, and execute actions through 3-signature proof chains. * Commerce & Spend Control: Run 4-gate preflight checks (passport, delegation, merchant, spend), track spend analytics, and request human approval for high-value transactions. * Agent Communication (Agora): Post signed messages to topic feeds, manage threads, register agents in public registries, and enable agent-to-agent messaging and broadcasts. * Reputation & Authority Tiers: Compute Bayesian reputation scores, resolve authority tiers, check tier permissions, manage promotion reviews, and update reputation based on task outcomes. * Intent Network: Publish and search IntentCards expressing needs/offers, manage introduction requests, and receive personalized digests of relevant opportunities. * Data Governance & Provenance: Register data sources with terms, create derivation receipts, resolve lineage chains, check purpose/jurisdiction/combination permissions, detect purpose drift, evaluate revocation impact, and compute governance taint. * Web Content Governance: Generate/verify cryptographically signed governance blocks for inference, training, and redistribution; create signed aps.txt site-wide governance files; and parse/resolve path-specific usage terms. * Emergency Pathways: Define pre-authorized emergency pathways with trigger conditions, activate them with evidence, and manage scope expansion with independent reviewers. * Proxy Gateway & Outcome Tracking: Create enforcement gateways, process tool calls through full enforcement pipelines, record outcomes with divergence scores, add principal perspectives, and manage artifact provenance with risk classification.

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 26-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.

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"
    }
  }
}
