1. Introduction

Prometheus Alertmanager MCP is a Model Context Protocol (MCP) server for Prometheus Alertmanager. It enables AI assistants and tools to query and manage Alertmanager resources programmatically and securely.

2. Features

• Query Alertmanager status, alerts, silences, receivers, and alert groups
• Create, update, and delete silences
• Create new alerts
• Authentication support (Basic auth via environment variables)
• Docker containerization support

3. Quickstart

3.1. Prerequisites

• Python 3.12+
• uv (for fast dependency management).
• Docker (optional, for containerized deployment).
• Ensure your Prometheus Alertmanager server is accessible from the environment where you'll run this MCP server.

3.2. Installing via Smithery

To install Prometheus Alertmanager MCP Server for Claude Desktop automatically via Smithery:

3.3. Local Run

• Clone the repository:

• Configure the environment variables for your Prometheus server, either through a .env file or system environment variables:

• Add the server configuration to your client configuration file. For example, for Claude Desktop:

• Or install it using make command:

• Restart Claude Desktop to load new configuration.
• You can now ask Claude to interact with Alertmanager using natual 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"

3.4. Docker Run

• Run it with pre-built image (or you can build it yourself):

• Running with Docker in Claude Desktop:

This configuration passes the environment variables from Claude Desktop to the Docker container by using the -e flag with just the variable name, and providing the actual values in the env object.

• Get status: get_status()
• List alerts: get_alerts()
• List silences: get_silences()
• Create silence: post_silence(silence_dict)
• Delete silence: delete_silence(silence_id)
