Give AI assistants the power to query your Prometheus metrics.



A [Model Context Protocol][mcp] (MCP) server that 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



## Getting Started



### Prerequisites



- Prometheus server accessible from your environment

- MCP-compatible client (Claude Desktop, VS Code, Cursor, Windsurf, etc.)



### Installation Methods



Claude Desktop



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": ""

      }

    }

  }

}

```



Claude Code



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

```



VS Code / Cursor / Windsurf



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": ""

    }

  }

}

```



Docker Desktop



The easiest way to run the Prometheus MCP server is through Docker Desktop:





  Add to Docker Desktop




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)



Manual Docker Setup



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

```



Helm Chart (Kubernetes)



Deploy to Kubernetes using the Helm chart from the OCI registry:



```bash

helm install prometheus-mcp-server \

  oci://ghcr.io/pab1it0/charts/prometheus-mcp-server \

  --version 1.0.0 \

  --set prometheus.url="http://prometheus:9090"

```



With authentication:



```bash

helm install prometheus-mcp-server \

  oci://ghcr.io/pab1it0/charts/prometheus-mcp-server \

  --version 1.0.0 \

  --set prometheus.url="http://prometheus:9090" \

  --set auth.username="admin" \

  --set auth.password="secret"

```



With a custom values file:



```bash

helm install prometheus-mcp-server \

  oci://ghcr.io/pab1it0/charts/prometheus-mcp-server \

  --version 1.0.0 \

  -f values.yaml

```



See the [chart values](charts/prometheus-mcp-server/values.yaml) for all available configuration options.



### Configuration Options



| Variable | Description | Required |

|----------|-------------|----------|

| `PROMETHEUS_URL` | URL of your Prometheus server | Yes |

| `PROMETHEUS_URL_SSL_VERIFY` | Set to False to disable SSL verification | No |

| `PROMETHEUS_DISABLE_LINKS` | Set to True to disable Prometheus UI links in query results (saves context tokens) | No |

| `PROMETHEUS_REQUEST_TIMEOUT` | Request timeout in seconds to prevent hanging requests (DDoS protection) | No (default: 30) |

| `PROMETHEUS_USERNAME` | Username for basic authentication | No |

| `PROMETHEUS_PASSWORD` | Password for basic authentication | No |

| `PROMETHEUS_TOKEN` | Bearer token for authentication | No |

| `PROMETHEUS_CLIENT_CERT` | Path to client certificate file for mutual TLS authentication | No |

| `PROMETHEUS_CLIENT_KEY` | Path to client private key file for mutual TLS authentication | No |

| `REQUESTS_CA_BUNDLE` | Path to CA bundle file for verifying the server's TLS certificate (standard `requests` library env var) | No |

| `ORG_ID` | Organization ID for multi-tenant setups | No |

| `PROMETHEUS_MCP_SERVER_TRANSPORT` | Transport mode (stdio, http, sse) | No (default: stdio) |

| `PROMETHEUS_MCP_BIND_HOST` | Host for HTTP transport | No (default: 127.0.0.1) |

## Available Tools



| Tool | Category | Description |

| --- | --- | --- |

| `health_check` | System | Health check endpoint for container monitoring and status verification |

| `execute_query` | Query | Execute a PromQL instant query against Prometheus |

| `execute_range_query` | Query | Execute a PromQL range query with start time, end time, and step interval |

| `list_metrics` | Discovery | List all available metrics in Prometheus with pagination and filtering support |

| `get_metric_metadata` | Discovery | Get metadata for one metric or bulk metadata with optional filtering |

| `get_targets` | Discovery | Get information about all scrape targets |



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.

## 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.
