gRPC as an MCP Transport
summary
Argues that replacing JSON/HTTP MCP transports with Protobuf binary serialization over HTTP/2 gRPC cuts CPU and bandwidth overhead, removes HTTP/1.1 head‑of‑line blocking, and restores mTLS, XDS load balancing and method‑level auth without sidecar rewrites. Provides a repo mapping the July MCP spec to protobuf, a Python V2 gRPC dispatcher POC (call_tool and resources working) and a plan for pluggable transports and conformance tests to let existing gRPC backends accept MCP traffic natively.
