Capabilities

noVNC viewer URL

computer_use.viewer_url(session_id) returns a browser-accessible URL. Watch agents work in real time or take over manually.

Full HTTP method proxy

GET, POST, PUT, PATCH, DELETE proxied to in-VM API. Send click, type, scroll actions. Read state. Binary endpoints (screenshots) are streamed.

Browser automation built in

browser.create_session() gives you navigate(), click(), fill(), screenshot(), and extract_elements(). CSS selectors, configurable timeouts.

Pause and take over

Open the viewer URL in a browser, interact directly, then let the agent resume. Session state is preserved throughout.

How it works

Viewer URL, proxy actions, manual takeover

Get the viewer URL

computer_use.viewer_url(session_id) returns a noVNC link. Open it in any browser to watch or interact with the desktop.

Proxy actions through the API

computer_use.post(session_id, '/mouse/click', json_data={...}) sends input. computer_use.get(session_id, '/state') reads current state.

Take over when needed

Click into the viewer and operate manually. The VM does not reset. Resume API-driven automation when ready.
