The 15 best JavaScript MCP servers

The 15 JavaScript MCP servers worth your time, out of 2,993 we track - actively maintained, with real adoption, ranked on monthly installs, GitHub stars, and commit recency. Checked nightly.

Plain JavaScript servers keep the npm install story with zero build step, and many double as small CLIs. They tend to be lighter than their TypeScript cousins and quick to fork when you need a private variant.

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