Your Idea

Our company has been implementing MCP servers and clients. With our use case, we do not have a need for long live connections between the client and server. In fact, we cache the functions available from the servers in the client on startup and only establish a connection when the function call is requested by the LLM and close the connection after it's complete. We're deployed to EKS in AWS. Using SSE creates a bidirectional flow where one isn't necessary in our use case. Supporting REST or simple HTTP requests with JSON-RPC out of the box would reduce the complexity and remove the need for stickiness between requests from the client to the server.
