Authentication

Phoenix API key (system or user API key) bearer discovered Get token ↗

$ npx -y @arizeai/phoenix-mcp@latest --baseUrl https://my-phoenix.com --apiKey <your-api-key>

For Phoenix Cloud, create a space in Phoenix Cloud, then go to Settings → API Keys and click Add System Key to create an API key. The docs also distinguish user API keys, which are tied to a specific user. Use the created key as a bearer token. For self-hosted Phoenix, the REST docs say authentication may be disabled; if enabled, use an API key or admin secret configured for that deployment.
