Overview
Fixes trace propagation in
Environment._env_call_toolby falling back tomcp.server.lowlevel.server.request_ctxto extract_hud_trace_id/trace_idfrom MCP request metadata when it isn’t present in tool arguments or forwarded kwargs.Adds an async test that seeds
request_ctxwith meta and assertsAgentToolevaluation (run_eval) receives the expectedtrace_id.Written by Cursor Bugbot for commit ae9d592. This will update automatically on new commits. Configure here.
