"ddg-mcp": {
      "command": "uv",
      "args": [
        "--directory",
        "/PATH/TO/YOUR/INSTALLATION/ddg-mcp",
        "run",

      ]
  },

## Development

### Building and Publishing

To prepare the package for distribution:

1. Sync dependencies and update lockfile:
```bash
uv sync
```

2. Build package distributions:
```bash
uv build
```

This will create source and wheel distributions in the `dist/` directory.

3. Publish to PyPI:
```bash
uv publish
```

Note: You'll need to set PyPI credentials via environment variables or command flags:
- Token: `--token` or `UV_PUBLISH_TOKEN`
- Or username/password: `--username`/`UV_PUBLISH_USERNAME` and `--password`/`UV_PUBLISH_PASSWORD`

### Automated Publishing with GitHub Actions

This repository includes a GitHub Actions workflow for automated publishing to PyPI. The workflow is triggered when:

1. A new GitHub Release is created
2. The workflow is manually triggered via the GitHub Actions interface

To set up automated publishing:

1. Generate a PyPI API token:
   - Go to https://pypi.org/manage/account/token/
   - Create a new token with scope limited to the `ddg-mcp` project
   - Copy the token value (you'll only see it once)

2. Add the token to your GitHub repository secrets:
   - Go to your repository on GitHub
   - Navigate to Settings > Secrets and variables > Actions
   - Click "New repository secret"
   - Name: `PYPI_API_TOKEN`
   - Value: Paste your PyPI token
   - Click "Add secret"

3. To publish a new version:
   - Update the version number in `pyproject.toml`
   - Create a new release on GitHub or manually trigger the workflow

### Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging
experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).

You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command:

```bash
npx @modelcontextprotocol/inspector uv --directory /path/to/your/ddg-mcp run ddg-mcp
```

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
