    List all active and pending alerts from Prometheus.

  • prometheus_list_metrics

    List all metric names known to Prometheus, with optional substring filter.

  • prometheus_list_targets

    List Prometheus scrape targets, summarised by job and health.

  • prometheus_querywrite action

    Execute an instant PromQL query against Prometheus.

  • prometheus_query_rangewrite action

What the publisher says

From the Prometheus repository's README, as published. We do not edit it. Read it on GitHub

prometheus-mcp

<!-- mcp-name: io.github.mshegolev/prometheus-mcp -->

MCP server for Prometheus metrics and observability. Give Claude (or any MCP-capable agent) read access to your Prometheus instance — query metrics with PromQL, inspect active alerts, and explore scrape targets — without leaving the conversation.

Why another Prometheus MCP?

The existing Prometheus integrations require custom scripts or direct API knowledge. This server:

  • Speaks the standard Model Context Protocol over stdio — works with Claude Desktop, Claude Code, Cursor, and any MCP client.
  • Is read-only: all 5 tools carry readOnlyHint: true — zero risk of modifying Prometheus data.
  • Returns dual-channel output: structured JSON (structuredContent) for programmatic use + Markdown (content) for human-readable display.
  • Has actionable error messages that name the exact env var to fix and suggest a next step.
  • Supports Bearer token, HTTP Basic auth, or no auth (common for internal deployments).

Tools

v4.0 Advanced Alert Correlation Features

Version 4.0 introduces powerful new capabilities for AI agents to autonomously investigate production errors:

Cross-Instance Alert Correlation

  • Automatically identify related alerts across multiple Prometheus instances
  • Group alerts by service identifiers to understand incident scope
  • Detect cascading alert patterns with directional dependency inference

Root Cause Analysis

  • Anomaly detection in metrics with automatic seasonality adjustment
  • Dependency chain traversal from symptoms to potential root causes
  • Change point detection correlating alerts with recent deployments or config changes
  • Ranked root cause candidates based on evidence strength and impact analysis

Dependency Mapping & Health

  • Dynamic service dependency maps built from traffic correlation analysis
  • Cross-cluster dependency visualization showing service interoperation
  • Synthetic health probing to assess dependency resilience
  • Load shedding recommendations based on dependency fragility

Trend Analysis & Benchmarking

  • Historical pattern recognition for recurring alert schedules
  • Capacity forecasting to predict resource exhaustion
  • MTTR benchmarking comparing resolution times against historical data
  • Deviation detection triggering higher-priority notifications for pattern breaks

Integrated Analysis Tool

  • New federationanalyzealerts tool combining all v4.0 features
  • Unified output format optimized for AI agent consumption
  • Comprehensive incident context in a single tool call

Installation

Prometheus: common questions

Is Prometheus MCP server safe?
Mostly: it is graded B (78/100). Read the Prometheus safety report
How do I install Prometheus?
It runs on your machine. Copy the Claude Code, Cursor, VS Code or Claude Desktop config from the install section.
Does Prometheus need an API key?
Yes. The registry entry asks for PROMETHEUS_TOKEN, PROMETHEUS_PASSWORD.
Is Prometheus maintained?
The last commit was 87 days ago (2026-08-07). The latest release is v0.1.0.
What can I use instead of Prometheus?
Servers from other publishers that do the same job: Netdata MCP server.
How does Prometheus compare with other MCP servers?
safety score 78/100 (higher than 57% of 48,273 servers); tools 7 (the typical server has 7); tools that change things 29% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
