mcp-protocol-bind

What it does

An Alexa+ style MCP session accepts JSON-RPC 2.0 only after the protocol version is 2025-11-25 and the transport is Streamable HTTP.

How we built it

The leftover path accepted any JSON-RPC 2.0 event. The dest binds protocol_version == 2025-11-25 and transport == streamable-http before handle().
