mcp-playwright-cdp

This fork adds the ability to connect to an existing Chrome instance via CDP. To use this feature:

1. Launch Chrome with remote debugging enabled:

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --remote-debugging-port=9222

2. The server will automatically attempt to connect to the running Chrome instance first, before launching a new browser.
