A browser-automation MCP server for coding agents. Any Chromium browser, every profile at once, no domain blocklist.
A zero depedencies Claude in Chrome clone that attaches to your real browser profile. Any Chromium browser, every profile at once, no domain blocklist.
Explanation · Installation · Tools · License
An MCP server that drives real Chromium browsers over the Chrome DevTools Protocol, so a coding agent can open a page, click through it, fill forms, read the console and network log, and pull back whatever the page loaded.
It attaches to your existing profile rather than launching a clean automation profile. Whatever you are already logged into, the agent can use — no separate login flow, no cookie export. There is no domain blocklist.
- Many profiles at once. A detached broker process lets several agent sessions share one browser, and serves Chrome Default + Chrome work + Brave simultaneously. Each profile gets a stable id; browserselect pins one per agent session. - Refs, not screenshots. pageoutline or readpage hand back element refs like e214 that you pass straight to computer({action:"leftclick", ref:"e214"}). A screenshot costs ~1,296 tokens; a readpage is roughly 15× cheaper. Take a screenshot when you need to see something, not to locate it. - Big things go to disk. sourcesdownload writes files to a tree and returns only counts and a manifest path, so a 100 MB download never becomes a 100 MB string in context. - Incognito windows are supported, but all of them share one session: separate windows give you separate tab groups, not separate logins. Use separate profiles for isolated cookie jars.
