FAQ from Prefect MCP Server

What are the runtime requirements for Prefect MCP Server?

You need Python 3.9 or newer, a virtual environment tool like uv, and Prefect 3 installed. The server runs via uvx and requires the prefect-mcp-server package.

How is the Prefect MCP Server configured?

Configuration is done via a .cursor/mcp.json file that sets the command to uvx with arguments ["prefect-mcp-server"]. Environment variables such as PREFECT_API_URL and optionally PREFECT_API_KEY are set in a .env file.

What transport does the server use?

The server uses standard MCP transport over stdio, invoked via the uvx command as defined in the Cursor MCP configuration.
