Google Proposes gRPC as a Native Transport Layer for the Model Context Protocol

Summary

Google Cloud has published a proposal to add gRPC as a native transport mechanism for the Model Context Protocol (MCP), the open standard originally introduced by Anthropic for connecting AI models to external tools and data sources. MCP currently relies on HTTP with Server-Sent Events (SSE) for remote communication, and this proposal would add gRPC as an alternative transport, leveraging its strengths in bidirectional streaming, strong typing via Protocol Buffers, and mature ecosystem support f
