5 TOOLS AVAILABLE
OUR ASSESSMENT
- 4,524 GitHub stars.
- 27 commits on main in the last 30 days.
- Maintained by the Model Context Protocol project.
- Reference Go implementation.
- Supports all three MCP transports.
- Multi-licence repo during the documented MIT to Apache-2.0 transition; track for full Apache-2.0 cutover.
- Smaller community than mark3labs/mcp-go (8,690 stars) at present.
- API surface evolves with the protocol; pin versions in production.
SDK has no auth by default. Servers built with the SDK must add authentication; Go middleware patterns work well for this.
Go developers who want the official reference implementation; cloud-native teams that want both single-binary deploys and protocol guarantees; mark3labs/mcp-go users evaluating the official path.

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.
