* fix(mcp): skip session pooling for HTTP/SSE transports to avoid anyio RuntimeError (#3203)
HTTP/SSE transports use anyio.TaskGroup internally for streamable
connections. These task groups have cancel scopes bound to the async task
that created them, so closing a pooled session from a different task
raises RuntimeError. Restrict session pooling to stdio transports only.
* Potential fix for pull request finding
