Mcp Alertmanager

jeanlopezxyz/mcp-alertmanager

Connects Claude directly to Prometheus Alertmanager for querying and managing alerts without leaving your editor. Exposes 12 tools covering alert retrieval with filters, silence management, alert investigation, and correlation analysis to track down root causes. Ships as a native Go binary with built-in Kubernetes connectivity via client-go, so it can auto-connect to Alertmanager running in OpenShift clusters using the API proxy without port forwarding. Works via direct URL for standalone deployments or auto-detects kubeconfig for cluster environments. Useful when you're triaging incidents and want to query firing alerts, create silences, or investigate alert patterns conversationally instead of switching between the Alertmanager UI and your code.
