What does this PR do? What is the motivation?
Documents two additions to the MCP integration in LLM Observability:
MCP intent capture — a new opt-in feature (
DD_MCP_CAPTURE_INTENT/capture_intent=TrueinLLMObs.enable()) that requests the calling model describe why it chose each MCP tool. Adds the env var to the command-line setup reference, the parameter toLLMObs.enable(), and a new "MCP intent capture" section with both command-line and in-code examples.Expanded MCP server instrumentation details — replaces the single
ToolManager.call_toolentry with the new server-side instrumented methods (RequestResponder), adds theinitializeandtools/callMCP method coverage, and documents the tags recorded on server spans (mcp_method,mcp_session_id,client_name,client_version).Merge readiness
