What are the best Go mcp servers?

By maintained adoption — GitHub stars plus recent commit activity — github-mcp-server, MCP Toolbox for Databases and xiaohongshu-mcp lead the Go mcp servers in this index of 14. The full ranking is below; it reflects what is genuinely used and still maintained, not what pays.

Are these Go mcp servers open source and free?

Yes — every project on this page is open source and written primarily in Go. MIT is the most common licence here, on 6 of 14, across 5 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 Go mcp servers specifically?

Staying in your team's primary language — Go — 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: 12 of these 14 shipped in the last 90 days, and reading a quiet project's source is how you tell finished from abandoned.

Best Go mcp servers

The 14 open-source mcp servers written in Go in this index, ranked by real maintained adoption (GitHub stars and recent commit activity), never by sponsorship. github-mcp-server leads the set at 33,135 GitHub stars, and 12 of the 14 have shipped a commit in the last 90 days. Every project here is Go-first, self-hostable, and free to run; the trade-off is you host and maintain it yourself. Right now it's led by github-mcp-server (33k stars), with MCP Toolbox for Databases and xiaohongshu-mcp close behind. Rankings shift as projects gain stars and ship commits.
