Prometheus MCP Server
Prometheus MCP server enabling AI agents to query Prometheus monitoring data — executing PromQL queries, retrieving metric metadata, inspecting alert rules and firing alerts, and integrating Prometheus's open-source metrics monitoring into agent-driven SRE, incident response, and infrastructure observability workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Add TLS and auth proxy for production. No built-in auth. Community MCP. Network-restrict Prometheus. Store credentials securely.
⚡ Reliability
Best When
An agent needs to query a self-hosted Prometheus instance — for SRE automation, incident response, or infrastructure monitoring workflows in Kubernetes or on-prem environments.
Avoid When
You're using Datadog, CloudWatch, or other managed monitoring — or need log analytics rather than metrics.
Use Cases
- • Executing PromQL queries for metric analysis from SRE agents
- • Checking firing alerts and alert rules from incident response agents
- • Analyzing infrastructure health metrics from monitoring agents
- • Generating capacity planning reports from infrastructure agents
- • Diagnosing performance issues via metrics from debugging agents
- • Querying Kubernetes cluster metrics from DevOps agents
Not For
- • Teams using Datadog, New Relic, or cloud-native monitoring (use those MCPs)
- • Log-based analysis (Prometheus is metrics-only; use Loki or Elasticsearch for logs)
- • Long-term metrics storage (Prometheus retention is limited; use Thanos/Cortex)
Interface
Authentication
Prometheus auth depends on your deployment. Default Prometheus has no auth. Production deployments use nginx/OAuth proxy in front. Configure via Prometheus URL with optional basic auth or bearer token.
Pricing
Prometheus is free open source. MCP server is free. You pay only for infrastructure running Prometheus. No software licensing costs.
Agent Metadata
Known Gotchas
- ⚠ PromQL syntax is specific and complex — agents need PromQL knowledge for effective queries
- ⚠ Prometheus must be accessible from agent — network/firewall configuration required
- ⚠ Default Prometheus has no auth — production access should go through authenticated proxy
- ⚠ Metric names are environment-specific — agents need knowledge of your metric namespace
- ⚠ Range queries vs instant queries behave differently — use correct query type
- ⚠ Community MCP (pab1it0) — verify PromQL query coverage against your use cases
