Report #55210

[gotcha] Why are my MCP tools executing silently without audit logs?

Implement structured logging for all tool invocations, including the caller, parameters, and return status. Export logs to a SIEM or audit system. Do not rely on the LLM client to report tool usage.

Journey Context:
MCP servers often run as background services. Without server-side telemetry, a compromised agent could silently exfiltrate data or perform destructive actions via tools, and the infrastructure team would have zero visibility. Relying on the client \(LLM\) to log is insufficient as the client can be manipulated to hide its tracks.
