About Prometheus Alertmanager MCP Server

What is Prometheus Alertmanager MCP Server: Smart Alerts & Automated Workflows?

This server acts as a bridge between Claude AI and Prometheus Alertmanager, enabling AI-driven management of alerts through standardized interfaces. It leverages the Model Context Protocol (MCP) to provide smart alert handling, silence management, and automated workflows. Think of it as a translator that lets Claude understand and act on your monitoring alerts.

How to Use Prometheus Alertmanager MCP Server: Smart Alerts & Automated Workflows?

  1. Install dependencies: Ensure Node.js (v18+) is installed, then run npx alertmanager-mcp for a single use or npm install -g alertmanager-mcp for global access.
  2. Configure Claude: Edit the mcpServers section in your Claude for Desktop config file with your Alertmanager URL and Docker command (see example below).
  3. Interact via natural language: Ask Claude to "List active CPU alerts" or "Silence this alert for 2 hours" directly from the app.
{
  "mcpServers": {
    "alertmanager": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e", "ALERTMANAGER_URL=http://your-alertmanager:9093",
        "ghcr.io/kaznak/alertmanager-mcp:latest"
      ]
    }
  }
}

Prometheus Alertmanager MCP Server Features

Key Features of Prometheus Alertmanager MCP Server: Smart Alerts & Automated Workflows?

  • Smart Filtering: Use regex-based queries like alertname=~'CPU.*' to instantly narrow down alerts
  • Automated Silence Management: Create time-bound suppressions with commands like startsAt="2024-01-01T12:00"
  • Contextual Alert Details: Get full metadata for any alert via its unique fingerprint
  • Group Awareness: View alerts organized by Alertmanager's grouping logic
  • Production-Ready: Built with TypeScript, error handling, and 5s API timeouts

Use Cases of Prometheus Alertmanager MCP Server: Smart Alerts & Automated Workflows?

  • Incident Response Automation: Have Claude auto-silence flapping alerts while escalating critical issues
  • Shift Handovers: Generate summarized alert reports like "Show all unresolved alerts from last 8 hours"
  • Compliance Audits: Query silences by creator with filter="createdBy=~'ops_team'"
  • Learning from History: Analyze past alerts to identify recurring patterns using get-alerts active=false

Prometheus Alertmanager MCP Server FAQ

FAQ from Prometheus Alertmanager MCP Server: Smart Alerts & Automated Workflows?

Does this work with cloud Alertmanager instances?
Yes, as long as the server can reach the Alertmanager API endpoint
Can I customize silence durations?
Use ISO8601 timestamps - e.g., endsAt="2024-01-01T14:30" for precise control
What happens if Alertmanager is unreachable?
Graceful error handling with retries - Claude will ask to retry or check configuration
Do I need to run this server constantly?
Only during active Claude sessions - Docker ensures zero downtime restarts

Prometheus Alertmanager MCP Server

This project implements a Model Context Protocol (MCP) server that integrates with Prometheus Alertmanager. It serves as a bridge between Claude AI and Alertmanager, allowing Claude to interact with and manage alerts through a standardized interface.

Core Features

  1. Alert Retrieval : Fetches and formats current alerts from Alertmanager with optional filtering capabilities.

  2. Alert Details : Provides detailed information about specific alerts when referenced by their fingerprint.

  3. Silence Management : Offers tools to create, list, and delete silences that suppress notifications for specific alerts.

  4. Alert Grouping : Retrieves alert groups as organized by Alertmanager.

Technical Implementation

Installation

Prerequisites

Setup

The package is available on npm and can be used directly with npx:

npx alertmanager-mcp

For global installation:

npm install -g alertmanager-mcp
alertmanager-mcp

Usage with Claude for Desktop

  1. Configure Claude for Desktop to use the MCP server by editing the configuration file:
{
  "mcpServers": {
    "alertmanager": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "--network=host",
        "-e", "ALERTMANAGER_URL=http://your-alertmanager-url:9093",
        "ghcr.io/kaznak/alertmanager-mcp:latest"
      ],
      "env": {}
    }
  }
}
  1. Restart Claude for Desktop to load the new configuration.

  2. You can now ask Claude to interact with Alertmanager using natural language:

* "Show me current alerts"
* "Filter alerts related to CPU issues"
* "Get details for this alert"
* "Create a silence for this alert for the next 2 hours"
