MCP Observability: Logging, Auditing, and Debugging Agent-Server Interactions in Production

Your agent ran overnight. One workflow failed halfway through. Three tool calls completed successfully. Two didn't. You're not sure in which order. What do you actually have to debug with? For most MCP setups, the honest answer is: not much. Server logs are sparse. Client-side tracing is application-specific. Audit trails are nonexistent. And because MCP interactions happen through a protocol layer, standard API debugging tools don't apply cleanly. This is the observability gap in production MCP deployments - and it compounds as you scale to multi-agent, multi-server architectures.
