Deprecated 27-Nov-2025

I've personally moved my efforts to a more generic OpenAPI spec based MCP: https://github.com/allen-munsch/yas-mcp

Additionally, there is actually an official beta release by prefect over here: https://pypi.org/project/prefect-mcp/

Prefect MCP Server

A Model Context Protocol (MCP) server implementation for Prefect, enabling AI assistants to interact with Prefect through natural language.

Note: The official Prefect MCP server is available here. This is a community implementation.
