Thanks @aniket-s-kulkarni for making this available. With this PR being merged,

1. I assume we can connect to MCP server endpoint http://127.0.0.1:8000/mcp with streamable http and should I provide any Bearer token for my local testing.
2. Our Dremio (software) co-ordinator is used very lightly, Do you think it is ok to deploy on same co-ordinator (assuming port 8000 is not used for anything Dremio) or recommend deploying on a different server

@rdkworld this is a preparatory PR. There will be a few more before the functionality is complete and can be used.

Oh ok, Thanks for the clarification @aniket-s-kulkarni , will wait for complete functionality. I guess I will hold off on wrapper/proxy I was building over stdio server since that would be throw-away effort once streamable-http support is available
