protoc-gen-go-mcp is a plugin for the Protocol Buffers compiler that creates Model Context Protocol (MCP) servers from your gRPC or ConnectRPC services. It generates *.pb.mcp.go files for each protobuf service, enabling delegation of handlers directly to MCP servers or clients. It supports JSON Schema inputs derived automatically from method descriptors, facilitating integration and automation in API workflows.
