How do I install the runtime mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `ANTHROPIC_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Runtime MCP Server?

Grackle GenAIScript runtime implementation

What you get

That's the collective noun. Also what you get when you stop babysitting one agent in a terminal and start running many — each on its own wire, with its own key, leaving its own name in the log.

Configuration and credentials

Docker (recommended — the Grackle app and its dependencies are bundled in the image) - Node.js >= 22, < 24 (for npm install — Node 24+ is not yet supported) > You still need to provide your own model credentials (via environment variables or mounted config files). Some features like the Docker adapter require access to the host Docker socket.
