Plugin request for Buf Schema Registry: grpc-mcp-gateway #2244

Mandatory

Where is the source code for the plugin?

https://github.com/linkbreakers-com/grpc-mcp-gateway/tree/main/cmd/protoc-gen-mcp-gateway

Does the plugin have a valid semver version?

Yes. Latest version is v0.4.0, taken from the git tags in the repository: https://github.com/linkbreakers-com/grpc-mcp-gateway

Does the plugin have a dependency on another plugin?

Yes. The generated code references types from the proto file being compiled (e.g. HelloRequest, GreeterClient), which means it depends on the output of protoc-gen-go and protoc-gen-go-grpc:

• https://github.com/protocolbuffers/protobuf-go/tree/master/cmd/protoc-gen-go
• https://github.com/grpc/grpc-go/tree/master/cmd/protoc-gen-go-grpc

Does the output of this plugin depend on any other external libraries?

Yes. The generated code imports two runtime dependencies:

1. github.com/linkbreakers-com/grpc-mcp-gateway/runtime the gateway runtime (decode/encode helpers)
2. github.com/modelcontextprotocol/go-sdk/mcp the MCP Go SDK
