# Quick Start — Register Your First Agent

This guide gets you from zero to a working agent identity with a valid OAuth 2.0 access token. It takes under 5 minutes.

## Prerequisites

You need two tools installed:

- **Docker** (includes `docker-compose`) — to run PostgreSQL and Redis
- **Node.js 18+** (includes `npm`) — to run the server
- **curl** — to call the API

Nothing else. No accounts, no sign-ups.

---

## Step 1 — Clone and configure

```bash
git clone https://git.sentryagent.ai/vijay_admin/sentryagent-idp.git
cd sentryagent-idp
npm install
```

Generate an RSA keypair for signing tokens (required):

```bash
# Generate private key
openssl genrsa -out private.pem 2048

# Extract public key
openssl rsa -in private.pem -pubout -out public.pem
```

Create your `.env` file:

```bash
cat > .env << 'EOF'
DATABASE_URL=postgresql://sentryagent:sentryagent@localhost:5432/sentryagent_idp
REDIS_URL=redis://localhost:6379
PORT=3000
JWT_PRIVATE_KEY="$(cat private.pem)"
JWT_PUBLIC_KEY="$(cat public.pem)"
EOF
```

> **Note**: The `.env` file stores your private key. Do not commit it to version control.

---

## Step 2 — Start infrastructure

Start PostgreSQL and Redis using Docker Compose (infrastructure services only):

```bash
docker-compose up -d postgres redis
```

Expected output:

```
[+] Running 2/2
 ✔ Container sentryagent-idp-postgres-1  Healthy
 ✔ Container sentryagent-idp-redis-1     Healthy
```

Services are ready when both show `Healthy`. Run migrations:

```bash
npm run db:migrate
```

Expected output:

```
Running database migrations...
  ✓ Applied: 001_create_agents.sql
  ✓ Applied: 002_create_credentials.sql
  ✓ Applied: 003_create_tokens.sql
  ✓ Applied: 004_create_audit_log.sql

Migrations complete. 4 migration(s) applied.
```

---

## Step 3 — Start the AgentIdP server

```bash
npm run dev
```

Expected output:

```
SentryAgent.ai AgentIdP listening on port 3000
Database pool connected
Redis client connected
```

The API is now live at `http://localhost:3000/api/v1`.

---

## Step 4 — Generate a bootstrap token

All API endpoints require a Bearer token. For first-time setup, generate a bootstrap token using your RSA private key:

```bash
node -e "
const jwt = require('jsonwebtoken');
const fs = require('fs');
const { v4: uuidv4 } = require('uuid');
const key = fs.readFileSync('private.pem', 'utf8');
const now = Math.floor(Date.now() / 1000);
const token = jwt.sign({
  sub: 'bootstrap',
  client_id: 'bootstrap',
  scope: 'agents:read agents:write tokens:read audit:read',
  jti: uuidv4(),
  iat: now,
  exp: now + 3600
}, key, { algorithm: 'RS256' });
console.log(token);
"
```

Copy the token output and export it:

```bash
export BOOTSTRAP_TOKEN="<paste token here>"
```

> This bootstrap token is a one-time tool for registering your first agent. Once you have an agent with credentials, use `POST /token` for all subsequent authentication.

---

## Step 5 — Register an agent

```bash
curl -s -X POST http://localhost:3000/api/v1/agents \
  -H "Authorization: Bearer $BOOTSTRAP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "my-first-agent@myproject.ai",
    "agentType": "custom",
    "version": "1.0.0",
    "capabilities": ["data:read"],
    "owner": "my-team",
    "deploymentEnv": "development"
  }' | jq .
```

Example response (`201 Created`):

```json
{
  "agentId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "email": "my-first-agent@myproject.ai",
  "agentType": "custom",
  "version": "1.0.0",
  "capabilities": ["data:read"],
  "owner": "my-team",
  "deploymentEnv": "development",
  "status": "active",
  "createdAt": "2026-03-28T09:00:00.000Z",
  "updatedAt": "2026-03-28T09:00:00.000Z"
}
```

Save the `agentId`:

```bash
export AGENT_ID="a1b2c3d4-e5f6-7890-abcd-ef1234567890"
```

---

## Step 6 — Generate a credential

```bash
curl -s -X POST "http://localhost:3000/api/v1/agents/$AGENT_ID/credentials" \
  -H "Authorization: Bearer $BOOTSTRAP_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{}' | jq .
```

Example response (`201 Created`):

```json
{
  "credentialId": "c9d8e7f6-a5b4-3210-fedc-ba9876543210",
  "clientId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "clientSecret": "sk_live_7f3a2b1c9d8e4f0a6b5c3d2e1f0a9b8c",
  "status": "active",
  "createdAt": "2026-03-28T09:00:00.000Z",
  "expiresAt": null,
  "revokedAt": null
}
```

> **Save the `clientSecret` now.** It is shown once and never retrievable again. The server stores only a bcrypt hash.

```bash
export CLIENT_ID="a1b2c3d4-e5f6-7890-abcd-ef1234567890"   # same as AGENT_ID
export CLIENT_SECRET="sk_live_7f3a2b1c9d8e4f0a6b5c3d2e1f0a9b8c"
```

---

## Step 7 — Issue an access token

Use the OAuth 2.0 Client Credentials flow. Note that the `/token` endpoint uses **form-encoded** body, not JSON:

```bash
curl -s -X POST http://localhost:3000/api/v1/token \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "grant_type=client_credentials" \
  -d "client_id=$CLIENT_ID" \
  -d "client_secret=$CLIENT_SECRET" \
  -d "scope=agents:read agents:write" | jq .
```

Example response (`200 OK`):

```json
{
  "access_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...",
  "token_type": "Bearer",
  "expires_in": 3600,
  "scope": "agents:read agents:write"
}
```

```bash
export TOKEN="eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9..."
```

Your agent now has a valid JWT. Use it in the `Authorization: Bearer <token>` header for all API calls.
