Add the Prometheus MCP server to Cursor

Config last verified Jun 1, 2026

The exact config to run Prometheus in Cursor — paste it in, restart, and the tools load.

Prerequisites

Cursor installed.
PROMETHEUS_URL — Base URL of your Prometheus-compatible HTTP API, e.g. http://localhost:9090.

Setup

1. Open `~/.cursor/mcp.json`

2. Add this configuration

Add to ~/.cursor/mcp.json

~/.cursor/mcp.json

json

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

3. Restart Cursor and confirm the Prometheus tools load.

Gotchas

Cursor keeps MCP servers under an "mcpServers" object in ~/.cursor/mcp.json for global use, and also reads a project-scoped .cursor/mcp.json so a repository can ship its own servers. Remote servers are configured with a bare "url" field and connect natively, with OAuth handled in-app when a server requires it.
