5 TOOLS AVAILABLE
OUR ASSESSMENT
- 12,422 GitHub stars.
- 18 commits on main in the last 30 days.
- Maintained by the Model Context Protocol project.
- Zod-based tool schemas with type inference.
- Reference TypeScript implementation.
- Multi-licence repo during the documented MIT to Apache-2.0 transition; track for full Apache-2.0 cutover.
- SDK-level scope; ergonomics improved by frameworks like FastMCP-TS.
- API surface evolves with the protocol; pin versions in production.
SDK has no auth by default. Servers built with the SDK must add authentication for production. Zod schemas help validate inputs but do not replace authentication.
TypeScript and JavaScript developers building MCP servers; teams that prefer Zod over ad-hoc schema validation; FastMCP-TS users who want to peek beneath the abstraction.

SOURCES & VERIFICATION
We don't take any single directory's word for it. Before scoring, we cross-reference 5 public MCP sources, install the server ourselves against the clients we cover, and record when we last re-verified.
The same server, 5 different lenses. We reconcile these signals into our editorial score, which is why our number sometimes diverges from a directory-aggregate star count.
