Extend MCP server to support streamable HTTP transport #5768
Description
What is the problem this feature would solve?
The best practice insofar as the MCP protocol is with streamable HTTP, as detailed here. JSON-RPC, which is what @effect/ai/McpServer currently supports, is not the latest best practice.
What is the feature you are proposing to solve the problem?
Requesting to add layerStreamableHttp or some such to the McpServer module so that this protocol is supported.
What alternatives have you considered?
I've tried using the reference implementation, and it works fine, but it's not as user-friendly in chatbot integrations. Case in point, it won't dynamically discover the available MCP capabilities with JSON-RPC as it would with streamable HTTP requests. There are other limitations as well.
