Prometheus MCP server for AI agents

The Prometheus MCP server provides a standardized Model Context Protocol interface for AI assistants to access and analyze your Prometheus metrics. It allows AI tools to execute PromQL queries, discover metrics, and help with monitoring data analysis through a well-defined API.

Installation

Docker Installation (Recommended)

The simplest way to run the Prometheus MCP server is using Docker:

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

If your Prometheus server requires authentication, add the credentials:

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

}

Configuration

Environment Variables

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 results	No
`PROMETHEUS_USERNAME`	Username for basic authentication	No
`PROMETHEUS_PASSWORD`	Password for basic authentication	No
`PROMETHEUS_TOKEN`	Bearer token for authentication	No
`ORG_ID`	Organization ID for multi-tenant setups	No
`PROMETHEUS_MCP_SERVER_TRANSPORT`	Transport mode (stdio, http, sse)	No
`PROMETHEUS_MCP_BIND_HOST`	Host for HTTP transport	No
`PROMETHEUS_MCP_BIND_PORT`	Port for HTTP transport	No

Available Tools

The Prometheus MCP server provides the following tools for AI assistants to interact with your metrics:

Query Tools

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

Discovery Tools

list_metrics: Browse all available metrics with pagination and filtering
get_metric_metadata: Retrieve metadata for specific metrics
get_targets: Get information about all scrape targets

System Tools

health_check: Verify the server is functioning correctly

Usage Examples

Once configured, your AI assistant can use these tools to help you analyze metrics. For example, you could ask:

"Show me CPU usage for the last hour"
"List all available metrics related to memory"
"What's the current request rate on our API endpoints?"
"Graph the error rate over the past day"

The AI will use the appropriate MCP tools to query your Prometheus server and return meaningful analysis.

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.

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": {

                "-e",
                "PROMETHEUS_URL",
                "ghcr.io/pab1it0/prometheus-mcp-server:latest"
            ],
            "env": {
                "PROMETHEUS_URL": "<url>"
            }
        }
    }
}
