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

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

npx -y @smithery/cli install @ntk148v/alertmanager-mcp-server --client claude

3.3. Local Run

• Clone the repository:

# Clone the repository
$ git clone https://github.com/ntk148v/alertmanager-mcp-server.git

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

# Set environment variables (see .env.sample)
ALERTMANAGER_URL=http://your-alertmanager:9093
ALERTMANAGER_USERNAME=your_username  # optional
ALERTMANAGER_PASSWORD=your_password  # optional

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

{
  "mcpServers": {
    "alertmanager": {
      "command": "uv",
      "args": [
        "--directory",
        "", "run", "src/alertmanager_mcp_server/server.py" ], "env": { "ALERTMANAGER_URL": "http://your-alertmanager:9093s", "ALERTMANAGER_USERNAME": "your_username", "ALERTMANAGER_PASSWORD": "your_password" } } } } ``` - Or install it using make command: ```shell $ make install ``` - 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" ![](./images/sample1.jpg) ![](./images/sample2.jpg) ### 3.4. Docker Run - Run it with pre-built image (or you can build it yourself): ```bash $ docker run -e ALERTMANAGER_URL=http://your-alertmanager:9093 \ -e ALERTMANAGER_USERNAME=your_username \ -e ALERTMANAGER_PASSWORD=your_password \ -p 8000:8000 ghcr.io/ntk148v/alertmanager-mcp-server ``` - Running with Docker in Claude Desktop: ```json { "mcpServers": { "alertmanager": { "command": "docker", "args": [ "run", "--rm", "-i", "-e", "ALERTMANAGER_URL", "-e", "ALERTMANAGER_USERNAME", "-e", "ALERTMANAGER_PASSWORD", "ghcr.io/ntk148v/alertmanager-mcp-server:latest" ], "env": { "ALERTMANAGER_URL": "http://your-alertmanager:9093s", "ALERTMANAGER_USERNAME": "your_username", "ALERTMANAGER_PASSWORD": "your_password" } } } } ``` 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. ## 4. Tools The MCP server exposes tools for querying and managing Alertmanager, following [its API v2](https://github.com/prometheus/alertmanager/blob/main/api/v2/openapi.yaml): - Get status: `get_status()` - List alerts: `get_alerts()` - List silences: `get_silences()` - Create silence: `post_silence(silence_dict)` - Delete silence: `delete_silence(silence_id)` - List receivers: `get_receivers()` - List alert groups: `get_alert_groups()` See [src/alertmanager_mcp_server/server.py](src/alertmanager_mcp_server/server.py) for full API details. ## 5. Development Contributions are welcome! Please open an issue or submit a pull request if you have any suggestions or improvements. This project uses [uv](https://github.com/astral-sh/uv) to manage dependencies. Install uv following the instructions for your platform. ```bash # Clone the repository $ git clone https://github.com/ntk148v/alertmanager-mcp-server.git $ cd alertmanager-mcp-server $ make setup # Run test $ make test # Run in development mode $ mcp dev $ TRANSPORT_MODE=sse mcp dev # Install in Claude Desktop $ make install ``` ## 6.
