A gRPC Transport for the Model Context Protocol
summary
Proposes using gRPC as the native transport for the Model Context Protocol and supplies a one-to-one native proto schema that maps MCP JSON types to protobuf primitives, splits MCP operations into distinct RPCs, and wires a pluggable gRPC dispatcher into the Python SDK so existing MCP logic stays unchanged. Shows concrete operational wins: smaller binary messages, HTTP/2 multiplexing, built‑in retries/deadlines, mTLS and XDS support. Publishes an experimental Python package and plans conformance tests and a migration playbook.
