Setup

You need to set up Datadog API and application keys:

1. Get your API key and application key from the Datadog API Keys page
2. Install dependencies in the datadog-mcp project:

   npm install
   # or
   pnpm install

3. Build the TypeScript project:

   npm run build
   # or
   pnpm run build

Docker Setup

You can build using Docker with the following command:

docker build -t datadog-mcp .

Usage with Claude Desktop

To use this with Claude Desktop, add the following to your claude_desktop_config.json:

{
  "mcpServers": {
    "datadog": {
      "command": "node",
      "args": [
        "/path/to/datadog-mcp/build/index.js"
      ],
      "env": {
        "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
        "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
      }
    }
  }
}

If you're using Docker, you can configure it like this:

{
  "mcpServers": {
    "datadog": {
      "command": "docker",
        "args": [
          "run",
          "-i",
          "--rm",
          "-e",
          "DD_API_KEY",
          "-e",
          "DD_APP_KEY",
          "datadog-mcp"
        ],
      "env": {
        "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
        "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
      }
    }
  }
}

Usage with VS Code

For quick installation in VS Code, configure your settings:

1. Open User Settings (JSON) in VS Code (Ctrl+Shift+P → Preferences: Open User Settings (JSON))
2. Add the following configuration:

{
  "mcp": {
    "servers": {
      "datadog": {
        "command": "node",
        "args": [
          "/path/to/datadog-mcp/build/index.js"
        ],
        "env": {
          "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
          "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
        }
      }
    }
  }
}

If you're using Docker, you can configure it like this:

{
  "mcp": {
    "servers": {
      "datadog": {
        "command": "docker",
          "args": [
          "run",
          "-i",
          "--rm",
          "-e",
          "DD_API_KEY",
          "-e",
          "DD_APP_KEY",
          "datadog-mcp"
        ],
        "env": {
          "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
          "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
        }
      }
    }
  }
}

Alternatively, you can add this to a .vscode/mcp.json file in your workspace (without the mcp key):

{
  "servers": {
    "datadog": {
      "command": "node",
      "args": [
        "/path/to/datadog-mcp/build/index.js"
      ],
      "env": {
        "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
        "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
      }
    }
  }
}

If you're using Docker, you can configure it like this:

{
  "servers": {
    "datadog": {
      "command": "docker",
        "args": [
          "run",
          "-i",
          "--rm",
          "-e",
          "DD_API_KEY",
          "-e",
          "DD_APP_KEY",
          "datadog-mcp"
        ],
      "env": {
        "DD_API_KEY": "<YOUR_DATADOG_API_KEY>",
        "DD_APP_KEY": "<YOUR_DATADOG_APP_KEY>"
      }
    }
  }
}
