概览

What is protoc-gen-go-mcp?

protoc-gen-go-mcp is a protoc plugin that generates Go Model Context Protocol (MCP) server code from protobuf service definitions. It integrates with the protobuf ecosystem and gRPC to produce MCP tools that can be used by LLM clients.

How to use protoc-gen-go-mcp?

Install via Homebrew (brew tap juliendoutre/protoc-gen-go-mcp and brew install protoc-gen-go-mcp), then run protoc with the --go-mcp_out flag after installing protoc, protoc-gen-go, and protoc-gen-go-grpc. An example invocation is provided: protoc ./example/api.proto --go_out=./example/ --go-grpc_out=./example/ --go-mcp_out=./example/. The generated MCP server can be run and configured in an IDE like Cursor by adding its command to the MCP configuration file.
