Prefect MCP Server

What is Prefect MCP Server?

Prefect MCP Server is a configuration that uses the prefect-mcp-server package to provide a Model Context Protocol server for Prefect, designed for use with the Cursor IDE. It relies on uvx for reliable execution and requires Prefect 3, Python 3.9+, and a virtual environment tool such as uv.

How to use Prefect MCP Server?

Install Prefect MCP Server by creating a virtual environment (e.g., uv venv --python 3.12 && source .venv/bin/activate) and running uv pip install -U prefect-mcp-server. Configure the server via the .cursor/mcp.json file with the command uvx and argument prefect-mcp-server. Set environment variables like PREFECT_API_URL and optionally PREFECT_API_KEY in a .env file. Start the server manually with uv run <script> or let Cursor IDE invoke it automatically from the configuration.
