The 15 best developer tools MCP servers

The 15 developer tools MCP servers worth your time, out of 292 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.

Where we've compared two of these head-to-head, the comparison is linked on each one's page.
