gRPC as the Native Transport for Agent Protocols (A2A and MCP)
summary
gRPC is implemented as a native transport for MCP/A2A so tools no longer need HTTP wrappers and can use gRPC features like load balancing, TLS, interceptors and proxyless meshes; the MCP Python SDK exposes a pluggable transport abstraction so client APIs stay identical and the server side flips transport with a one-line switch in run(...); there is an SE-1352 proposal, a demoed Python implementation, and a C++ SDK open-source by year end roadmap.
