We want to introduce gRPC as native transport for Model Context Protocol.

As we know gRPC is already well establish in microservices, these services are now evolving as tools for AI.

Using gRPC as native transport for MCP have following advantages
1. Authentication and Authorization features of gRPC channels can be used for transport.
2. As gRPC uses protobuf, hence we get the advantage of more throughput and less bandwidth usage.
3. gRPC already has streaming capabilities which can be used for MCP as required.
4. It would be less frictional for micro-services to have their services as MCP using gRPC transport as infra remains the same.
5. Protobuf specification creates strong API contracts between various language implementations.
6. As gRPC supports proxy-less service mesh, MCP servers having gRPC transport can take advantage of it for various features such as load balancing, MTLS etc.
