What is MCP observability?

Logging, auditing, debugging for agent-server tool calls in production — who, what creds, outcomes, side effects.

JSON events per call: tool, agent_id, input_summary, outcome, idempotent, side_effects. Session summaries. Governors for spend.

No. But it turns guesswork into fixes — fast recovery, spend control, audit trails.
