Manual (macOS / Linux)

# Pick your platform, e.g. darwin_arm64 / linux_amd64
curl -LO https://github.com/the-protobuf-project/grpc-mcp-gateway/releases/download/v1.6.0/protoc-gen-mcp_1.6.0_darwin_arm64.tar.gz
tar -xzf protoc-gen-mcp_1.6.0_darwin_arm64.tar.gz

Proto annotations

The MCP proto annotations are published to the Buf Schema Registry; add them
as a dependency and generate types in your own client:

# buf.yaml
deps:
  - buf.build/the-protobuf-project/mcp

Then reference the plugin from buf.gen.yaml:

plugins:
  - local: protoc-gen-mcp
    out: generated
    opt: [lang=go]   # go | python | rust | cpp | all
