Prometheus MCP server for AI agents

Prometheus MCP Server provides access to your Prometheus metrics and queries through standardized Model Context Protocol (MCP) interfaces, enabling AI assistants to execute PromQL queries and analyze metrics data. This server acts as a bridge between your Prometheus instances and AI tools, making your monitoring data accessible for analysis.

Features

Execute PromQL queries against Prometheus
Discover and explore metrics (list available metrics, get metadata, view instant/range query results)
Authentication support (basic auth and bearer token)
Docker containerization support
Configurable tools for AI assistants

Installation Methods

Docker (Recommended)

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

docker run -i --rm \
  -e PROMETHEUS_URL="http://your-prometheus:9090" \
  ghcr.io/pab1it0/prometheus-mcp-server:latest

Authentication Example

For Prometheus instances that require 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

Or with token authentication:

docker run -i --rm \
  -e PROMETHEUS_URL="http://your-prometheus:9090" \
  -e PROMETHEUS_TOKEN="your-token" \
  ghcr.io/pab1it0/prometheus-mcp-server:latest

Available Tools

The MCP server provides several tools that AI assistants can use to interact with your Prometheus data:

Query Tools

execute_query: Execute a PromQL instant query against Prometheus
execute_range_query: Execute a PromQL range query with start time, end time, and step interval

Discovery Tools

list_metrics: List all available metrics in Prometheus
get_metric_metadata: Get metadata for a specific metric
get_targets: Get information about all scrape targets

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "prometheus" '{"command":"docker","args":["run","-i","--rm","-e","PROMETHEUS_URL","ghcr.io/pab1it0/prometheus-mcp-server:latest"],"env":{"PROMETHEUS_URL":"<url>"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "prometheus": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "-e",
                "PROMETHEUS_URL",
                "ghcr.io/pab1it0/prometheus-mcp-server:latest"
            ],
            "env": {
                "PROMETHEUS_URL": "<url>"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "prometheus": {
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "-e",
                "PROMETHEUS_URL",
                "ghcr.io/pab1it0/prometheus-mcp-server:latest"
            ],
            "env": {
                "PROMETHEUS_URL": "<url>"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
