Alertmanager MCP Server
MCP server for Prometheus Alertmanager — the alert routing and management component of the Prometheus monitoring stack. Enables AI agents to query active alerts, manage silences, inspect alert routing, and interact with Alertmanager's alert deduplication and grouping capabilities for AI-driven SRE workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
No native auth — must add via proxy. Alert data is sensitive ops info. Silence creation has production impact.
⚡ Reliability
Best When
A site reliability engineer using Prometheus stack wants AI agents to query active alerts, manage silences, and assist with incident triage and on-call workflows.
Avoid When
You use Datadog, Grafana Cloud, or other managed monitoring. Also: Alertmanager should be paired with Prometheus MCP for full observability.
Use Cases
- • Querying active Prometheus alerts from AI incident response and on-call agents
- • Managing Alertmanager silences for planned maintenance from DevOps agents
- • Investigating alert routing and receiver configurations from SRE agents
- • Integrating Prometheus alerting data into AI-driven operations workflows
Not For
- • Teams not using Prometheus/Alertmanager stack
- • Managed monitoring services (Datadog, PagerDuty) without Prometheus
- • Real-time metric querying — use Prometheus MCP for that
Interface
Authentication
Alertmanager has no authentication by default. Use a reverse proxy with auth for production. Basic auth supported via proxy.
Pricing
Prometheus and Alertmanager are free open source (Apache 2.0). MCP server is free open source.
Agent Metadata
Known Gotchas
- ⚠ Alertmanager has NO built-in authentication — must be protected by reverse proxy in production
- ⚠ Silences created by agents affect real alert routing — test in non-production first
- ⚠ Alertmanager API v2 (OpenAPI spec) — verify API version against your Alertmanager deployment
- ⚠ Alert data contains infrastructure details — treat as sensitive operations data
