## Authentication
The SSE endpoint requires a valid GNS3 JWT token. It supports two ways to pass the token:
The SSE endpoint supports two types of credentials, passed the same way.
1. **Authorization header** (recommended for Claude Code):
1. **Authorization header** (recommended):
```
Authorization: Bearer <jwt>
Authorization: Bearer <jwt_or_api_key>
```
2. **Query parameter** (required for Claude Desktop, since EventSource does not support custom headers):
2. **Query parameter** (for clients that don't support custom headers):
```
GET /v3/mcp/transport/sse?token=<jwt>
GET /v3/mcp/transport/sse?token=<jwt_or_api_key>
```
### Getting a Token
### Option 1: JWT Token (24h expiry)
```bash
curl -X POST http://localhost:3080/v3/access/users/authenticate \

```
### Token Expiry
Default JWT token lifetime is **1440 minutes (24 hours)**. This can be configured in `gns3_server.conf`:
Default lifetime is **1440 minutes (24 hours)**. Configurable in `gns3_server.conf`:
```ini
jwt_access_token_expire_minutes = 1440 ; 24 hours
```
### Option 2: API Key (permanent, revocable) — Recommended for MCP
API keys never expire and can be revoked individually. Create one via the REST API:
```bash
# Create an API key (requires a JWT to authenticate)
curl -X POST http://localhost:3080/v3/access/api-keys \
-H "Authorization: Bearer <your_jwt>" \
-H "Content-Type: application/json" \
-d '{"name": "MCP Production"}'
# Response: {"api_key": "gns3_a1b2c3d4...", "api_key_id": "...", ...}
# ⚠️ The key is only shown once — save it immediately.
```
API key management endpoints:
| Endpoint | Description |
|----------|-------------|
| `POST /v3/access/api-keys` | Create a new key (returns plaintext once) |
| `GET /v3/access/api-keys` | List all your keys |
| `POST /v3/access/api-keys/{id}/revoke` | Revoke a key (can be restored) |
| `POST /v3/access/api-keys/{id}/restore` | Restore a revoked key |
| `DELETE /v3/access/api-keys/{id}` | Permanently delete a key |
Both JWT tokens and API keys work for MCP and REST API endpoints interchangeably.
