Development

Building and Publishing

To prepare the package for distribution:

  1. Sync dependencies and update lockfile:
uv sync
  1. Build package distributions:
uv build

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

  1. Publish to PyPI:
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:

  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.

You can launch the MCP Inspector via npm with this command:

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.
