Best Python mcp servers
The 50 open-source mcp servers written in Python in this index, ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. serena leads the set at 29,872 GitHub stars, and 45 of the 50 have shipped a commit in the last 90 days. Every project here is Python-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by serena (30k stars), with MCP for Blender (blender-mcp) and fastmcp close behind. Rankings shift as projects gain stars and ship commits.

Frequently asked
- What are the best Python mcp servers?
- By maintained adoption — GitHub stars plus recent commit activity — serena, MCP for Blender (blender-mcp) and fastmcp lead the Python mcp servers in this index of 50. The full ranking is below; it reflects what is genuinely used and still maintained, not what pays.
- Are these Python mcp servers open source and free?
- Yes — every project on this page is open source and written primarily in Python. MIT is the most common licence here, on 32 of 50, across 4 licences in total. The software is free to run and self-host; you still pay for the infrastructure you run it on and any model or API usage it makes.
- Why choose Python mcp servers specifically?
- Staying in your team's primary language — Python — makes self-hosting, extending, and debugging far easier, because you can read and modify the source directly instead of treating it as a black box. It also makes upstream activity something you can judge: 45 of these 50 shipped in the last 90 days, and reading a quiet project's source is how you tell finished from abandoned.
