Add the Prometheus MCP server to VS Code

Config last verified Jun 1, 2026

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

Prerequisites

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

Setup

1. Open `.vscode/mcp.json`

2. Add this configuration

Add to .vscode/mcp.json

.vscode/mcp.json

json

{
  "servers": {
    "prometheus": {
      "type": "stdio",
      "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>"
      }
    }
  }
}

Heads up

VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

3. Restart VS Code and confirm the Prometheus tools load.

Gotchas

VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
