The 15 best developer tools MCP servers

The 15 developer tools MCP servers worth your time, out of 358 we track - actively maintained, with real adoption, ranked on monthly installs, GitHub stars, and commit recency. Checked nightly.

Developer-tools MCP servers wrap everyday engineering utilities (linters, scaffolds, API explorers) as agent actions. Look for narrow, well-documented tools over kitchen-sink surfaces.

How to choose between them

Xcode Build MCP tops the list - the most installs (530,072 last month) and actively maintained. All 15 run locally as stdio servers. 10 document no required env vars - paste the config and go; the others need env vars set first (each page lists exactly which). Where we've compared two of these head-to-head, the comparison is linked on each one's page.

How this list is ranked

Ranked from live registry + GitHub data: monthly installs (npm/PyPI), GitHub stars, and commit recency - recomputed nightly. No pay-to-rank, ever. The 15 above lead the full list of 168, all of which you can see on this page. The other 190 we track have stopped being maintained, or nobody is using them yet. Full recipe: how we verify.
