• Screenshot resource URI: screenshot://{page_id}
• Screenshot resources are automatically available for all open pages

Prompts

The server provides a prompt to help clients interpret web pages:

• interpret-page: Analyzes the current web page content and structure
  • Optional page_id argument to select which page to interpret
  • Optional focus argument to focus on specific aspects (full, forms, navigation, text)
  • Returns both text analysis and a screenshot of the page

The server implements a comprehensive set of browser automation tools:

• Browser navigation

  • navigate: Go to a specific URL
  • new_page: Create a new browser page with a specific ID
  • switch_page: Switch to a different browser page
  • get_pages: List all available browser pages

Development

Building and Publishing

To prepare the package for distribution:

1. Sync dependencies and update lockfile:

uv sync

2. Build package distributions:

uv build

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

3. 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

Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debuggingexperience, we strongly recommend using the MCP Inspector.

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

npx @modelcontextprotocol/inspector uv --directory /Users/shannon/Workspace/artivus/playwright-mcp run playwright-mcp

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