MCP Monitoring Dashboard

Build an MCP monitoring dashboard for tool-call latency, errors, auth failures, redaction, and uptime.

Quick Answer / TL;DR

An MCP monitoring dashboard should show tool-call latency, error rate, auth failures, redaction events, token-heavy outputs, uptime, and per-client usage.

Key Takeaways

Track tool latency.
Alert on auth failures.
Redaction metrics reveal privacy risk.

Core dashboard panels

MCP observability should help operators answer three questions: is the server healthy, are tools safe, and where is latency coming from?

Panel	Why it matters
Tool latency p95	User experience
Error rate	Reliability
Auth failures	Attack or config signal
Redaction count	Privacy exposure signal
Output bytes	Cost and token pressure

Event payload

Log metadata, not raw secrets. Record request IDs so support and incident response can trace a tool call without exposing sensitive content.
