mcp-grpc-transport

Pluggable gRPC transport for Model Context Protocol (MCP) servers, built on @modelcontextprotocol/sdk (peer dep ^1.27.0). Current stable version 0.2.0 (pre-1.0, wire format may evolve). Exposes three protobuf service surfaces: grpc.health.v1.Health for Kubernetes probes, model_context_protocol.Mcp (unary/streaming RPCs like ListTools, CallTool) aligned with the community mcp-python-sdk-grpc-poc reference, and optional mcp.transport.v1.Mcp.Session for JSON-RPC over gRPC. Requires Node >=22 and ESM-only. TypeScript types included. Optional gRPC server reflection via ENABLE_GRPC_REFLECTION=1.
