What Page Agent does
- Page Agent runs as in-page JavaScript, with no browser extension, Python or headless browser required.
- Page Agent manipulates the page through the text-based DOM, without screenshots or multi-modal LLMs.
- Page Agent executes natural language instructions such as 'Click the login button' on the current page.
- Page Agent works with most mainstream LLMs, including locally deployed models.
- Page Agent offers an optional Chrome extension for multi-page tasks across browser tabs.
- Page Agent includes an MCP Server, in beta, so outside agent clients can control your browser.
How it works
You add Page Agent to your web page with a script tag or the npm package. You then create a PageAgent with a model name, base URL and API key, and call execute with a natural language task. Page Agent reads the page's DOM as text and acts on it inside the page. An optional Chrome extension and an MCP Server extend it across tabs and to outside clients.
