agent: mcp

When does this happen?

IF MCP client repeatedly sends resources/list and prompts/list requests even though the server has not advertised support for those capabilities.

How others solved it

THEN The MCP client should respect the server's declared capabilities in the initial server info and stop polling for unsupported list operations. Implement caching of capability declarations and skip periodic requests for capabilities the server does not support.
