Clr Sentry

MCP server extending Sentry with performance insights, cron monitors, alerts, and smart issue lookup.

Companion to the third-party selfhosted-sentry-mcp — this server adds capabilities that the base server doesn't support (Discover API with array fields, short ID resolution, monitor/alert CRUD).

Features

• Smart issue lookup — auto-detects numeric IDs, short IDs (e.g. MYPROJECT-1W), and full Sentry URLs
• Performance insights — top transactions, slow DB queries, slow HTTP requests, queue performance
• Custom Discover queries — proper array field support (field[] as repeated params)
• Events timeseries — trend visualization over time
• Cron monitor CRUD — list, get, create, update, delete
• Issue alert CRUD — project-scoped alert rules
• Metric alert CRUD — org-scoped metric alert rules
• Read-only mode — hide all write tools with SENTRY_READ_ONLY=true
• Response trimming — strips bloated fields (activity, participants) and truncates long SQL strings
