# 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

```bash
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):

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

Minimal MCP install (essential profile is the default; `APS_PROFILE=full` for all 150 tools):

```bash
npx agent-passport-system-mcp
```

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

## Core workflow

### 1. Create identity → returns passport + keypair

```bash
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

```bash
npx agent-passport delegate --to <publicKey> --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

```bash
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

```bash
npx agent-passport prove --beneficiary alice
```

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

## MCP tools (150 total on v3.2.1)

## Framework adapters (8)

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

```typescript
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

```typescript
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.
