Give your agent a working browser

Read websites, interact with pages and capture screenshots in a separate local browser.

Licences & source

Your agent gets agent-browser’s MCP tools for opening pages, reading their contents and interacting with buttons and forms. The browser stays open between tools for the life of that connection.

For a first result, supply a page address and get its screenshot and readable accessibility snapshot. This browser has its own session: it does not inherit your usual browser’s accounts, extensions or saved passwords.

You bring

  • a JSON object with url and optional width, height, full_page and wait_selectorpage.json

You get

  • a screenshot at the selected viewport or full page heightpage.png
  • the page's readable accessibility treesnapshot.txt
  • the page address, title, capture options and output checksumspage.json
  • agent-browser's navigation, page interaction and capture tools; browser state lasts for this MCP connection

Good to know

  • This is a headless CPU browser, not a connection to your signed-in desktop browser. Sites may require login or block automation.
  • Closing the MCP connection ends this browser process. Do not use it as persistent storage for an account or assume a new connection resumes an earlier page.
More setup notes
  • Chromium's sandbox is disabled inside the container. UGT's container boundary still applies; do not expose this MCP server as an unauthenticated public service.

Your files & access

  • The separate browser loads websites and the resources they request.

Licences & source

agent-browser Apache-2.0, with bundled notices; Chromium and its Debian dependencies retain their distribution notices. UGT's driver and checks are Apache-2.0.

What UGT sets up for you
How was it tested?

Run on clean x86-64 (Intel/AMD) and ARM64 machines on 10 Nov 2026. Its check passed on a known sample and rejected deliberately broken results.

This checks the job this page describes, not every feature of the original project.
