## Authentication

All tools that interact with the Interlynk platform require an API token. See [API Key Management](/administration/api-key-management.md) for token creation and management.

```bash
# Set once for pylynk
export INTERLYNK_SECURITY_TOKEN="lynk_service_your_token"

# Set once for lynk-mcp
lynk-mcp configure
```

{% hint style="warning" %}
Use **service tokens** for CI/CD and automation. Use **user tokens** only for local, interactive sessions. See [Least Privilege Recommendations](/administration/api-key-management.md#least-privilege-recommendations).
{% endhint %}
