A [Model Context Protocol][mcp] (MCP) server for Prometheus.
This provides access to your Prometheus metrics and queries through standardized MCP interfaces, allowing AI assistants to execute PromQL queries and analyze your metrics data.
[mcp]: https://modelcontextprotocol.io
## Features
- [x] Execute PromQL queries against Prometheus
- [x] Discover and explore metrics
- [x] List available metrics
- [x] Get metadata for specific metrics
- [x] View instant query results
- [x] View range query results with different step intervals
- [x] Authentication support
- [x] Basic auth from environment variables
- [x] Bearer token auth from environment variables
- [x] Docker containerization support
- [x] Provide interactive tools for AI assistants
The list of tools is configurable, so you can choose which tools you want to make available to the MCP client.
This is useful if you don't use certain functionality or if you don't want to take up too much of the context window.
## Getting Started
### Prerequisites
- Prometheus server accessible from your environment
- MCP-compatible client (Claude Desktop, VS Code, Cursor, Windsurf, etc.)
### Installation Methods
<details>
<summary><b>Claude Desktop</b></summary>
Add to your Claude Desktop configuration:
```json
{
"mcpServers": {
"prometheus": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-e",
"PROMETHEUS_URL",
"ghcr.io/pab1it0/prometheus-mcp-server:latest"
],
"env": {
"PROMETHEUS_URL": "<your-prometheus-url>"
}
}
}
}
```
</details>
<details>
<summary><b>Claude Code</b></summary>
Install via the Claude Code CLI:
```bash
claude mcp add prometheus --env PROMETHEUS_URL=http://your-prometheus:9090 -- docker run -i --rm -e PROMETHEUS_URL ghcr.io/pab1it0/prometheus-mcp-server:latest
```
</details>
<details>
<summary><b>VS Code / Cursor / Windsurf</b></summary>
Add to your MCP settings in the respective IDE:
```json
{
"prometheus": {
"command": "docker",
"args": [
"run",
"-i",
"--rm",
"-e",
"PROMETHEUS_URL",
"ghcr.io/pab1it0/prometheus-mcp-server:latest"
],
"env": {
"PROMETHEUS_URL": "<your-prometheus-url>"
}
}
}
```
</details>
<details>
<summary><b>Docker Desktop</b></summary>
The easiest way to run the Prometheus MCP server is through Docker Desktop:
<a href="https://hub.docker.com/open-desktop?url=https://open.docker.com/dashboard/mcp/servers/id/prometheus/config?enable=true">
<img src="https://img.shields.io/badge/+%20Add%20to-Docker%20Desktop-2496ED?style=for-the-badge&logo=docker&logoColor=white" alt="Add to Docker Desktop" />
</a>
1. **Via MCP Catalog**: Visit the [Prometheus MCP Server on Docker Hub](https://hub.docker.com/mcp/server/prometheus/overview) and click the button above
2. **Via MCP Toolkit**: Use Docker Desktop's MCP Toolkit extension to discover and install the server
3. Configure your connection using environment variables (see Configuration Options below)
</details>
<details>
<summary><b>Manual Docker Setup</b></summary>
Run directly with Docker:
```bash
# With environment variables
docker run -i --rm \
-e PROMETHEUS_URL="http://your-prometheus:9090" \
ghcr.io/pab1it0/prometheus-mcp-server:latest
# With authentication
docker run -i --rm \
-e PROMETHEUS_URL="http://your-prometheus:9090" \
-e PROMETHEUS_USERNAME="admin" \
-e PROMETHEUS_PASSWORD="password" \
ghcr.io/pab1it0/prometheus-mcp-server:latest
```
</details>

## Development
Contributions are welcome! Please see our [Contributing Guide](CONTRIBUTING.md) for detailed information on how to get started, coding standards, and the pull request process.
This project uses [`uv`](https://github.com/astral-sh/uv) to manage dependencies. Install `uv` following the instructions for your platform:
```bash
curl -LsSf https://astral.sh/uv/install.sh | sh
```
You can then create a virtual environment and install the dependencies with:
```bash
uv venv
source .venv/bin/activate # On Unix/macOS
.venv\Scripts\activate # On Windows
uv pip install -e .
```
### Testing
The project includes a comprehensive test suite that ensures functionality and helps prevent regressions.
Run the tests with pytest:
```bash
# Install development dependencies
uv pip install -e ".[dev]"
# Run the tests
pytest
# Run with coverage report
pytest --cov=src --cov-report=term-missing
```
When adding new features, please also add corresponding tests.
### Tools
| Tool | Category | Description |
