Agent Passport System

When to use this skill

Agent needs cryptographic identity (Ed25519 passport)

Delegate authority between agents with scope, spend limits, depth controls

Revoke access — one call kills all downstream delegations

Run agent commerce with 5-gate checkout (passport, delegation, merchant, spend)

Coordinate multi-agent tasks (assign, evidence, review, deliver)

Track data contributions with Merkle proofs

Encrypt agent-to-agent communication (E2E, forward secrecy)

Score agent trust (Bayesian reputation, passport grades 0-3)

Enforce values compliance (8 principles, graduated enforcement)

Found institutions with charters, offices, approval policies

Install

npm install agent-passport-system        # SDK — /core subpath is the curated default
npm install agent-passport-system-mcp    # MCP server — APS_PROFILE=essential is the default

Minimal SDK import (lead with the curated essentials):

import {
  createPassport, createDelegation,
  evaluateIntent, commercePreflight, generateKeyPair
} from 'agent-passport-system/core'

Minimal MCP install (essential profile is the default; APS_PROFILE=full for all 142 tools):

npx agent-passport-system-mcp

Remote MCP (zero install): https://mcp.aeoess.com/sse

Core workflow

1. Create identity → returns passport + keypair

npx agent-passport join --name my-agent --owner alice

Output: .passport/agent.json with Ed25519 keypair, signed passport, values attestation. Treat like an SSH key.

2. Delegate authority → returns signed delegation

npx agent-passport delegate --to  --scope web_search,commerce --limit 500 --depth 1 --hours 24

Output: signed delegation with scope, spend limit, max depth, expiry. Authority can only narrow at each transfer.

3. Record work → returns signed receipt

npx agent-passport work --scope web_search --type research --result success --summary "Found 3 sources"

Output: Ed25519-signed receipt traceable to a human through the delegation chain.

4. Prove contributions → returns Merkle proof

npx agent-passport prove --beneficiary alice

Output: Merkle root + inclusion proofs. 100K receipts provable with ~17 hashes.

MCP tools (150 total on v3.1.1)

Framework adapters (8)

One-function governance for every major agent framework. Each wraps tool/task execution with APS delegation checks and Ed25519-signed receipts.

import {
  governLangChainTool,              // LangChain/LangGraph
  governCrewTask,                   // CrewAI
  governMCPToolCall,                // Any MCP server
  governIBACIntent,                 // IBAC (Cedar/OPA)
  passportToA2ACard,                // A2A Agent Cards
} from 'agent-passport-system'
// Also available as standalone packages:
// npm install @aeoess/stripe-governance
// npm install @aeoess/composio-governance

| Adapter | Function | What it wraps | |---------|----------|--------------| | LangChain | governLangChainTool() | BaseTool.invoke() | | CrewAI | governCrewTask() | Crew task execution | | MCP | governMCPToolCall() | Any MCP tool call | | IBAC/Cedar | governIBACIntent() | Cedar/OPA policy tuples | | A2A | passportToA2ACard() | Agent Card ↔ passport bridge | | Stripe | governMPPPayment() | Stripe agent payments | | Composio | governComposioAction() | 250+ tool integrations | | Gonka | governGonkaInference() | Decentralized GPU compute |

Programmatic API

import {
  joinSocialContract,   // → { passport, keyPair, attestation }
  createDelegation,     // → signed Delegation
  processToolCall,      // → { permitted, constraintResults, receipt }
  cascadeRevoke,        // → { revoked: string[], receipts }
  computePassportGrade, // → 0 | 1 | 2 | 3
  createIssuanceContext, // → IssuanceContext with evidence + assessment
} from 'agent-passport-system'

Passport grades (attestation architecture)

| Grade | Meaning | Trust signal | |-------|---------|-------------| | 0 | Bare Ed25519 keypair | Unverified | | 1 | Issuer countersigned | AEOESS processed | | 2 | Runtime-bound + challenge-response | Infrastructure-attested | | 3 | Runtime + verified human principal | Full chain of trust |

Grade travels with the passport. Any consumer reads it without understanding scoring internals.

Key facts

Enforcement and accountability layer — bring your own identity, gateway does the rest

SDK /core subpath: 24 curated functions for 90% of integrations

MCP essential profile: 20 tools by default (identity, delegation, enforcement, commerce, reputation)

Policy eval <2ms, 403 ops/sec, 14 constraint dimensions

2,586 tests including 50 adversarial attack scenarios

Zero heavy dependencies — Node.js crypto + uuid only
