A local browser your coding agent can actually finish a job in — file uploads, cross-origin iframes, native dialogs, and downloads, all via CLI/MCP.
A headless browser your coding agent can actually finish a job in.
Claude Code and Codex get a real Chromium they drive from the outside — with none of the restrictions browsers place on in-page automation. So they can log into your internal tools, fill the forms, upload the file, and be done.
We wanted Claude to do a genuinely boring job: log into our internal admin tool, find a record, and attach a document. It got about 80% of the way and then stopped dead — every single time, at the same step.
Browsers require a real human gesture before opening a file picker. That's not a bug or an oversight; it's a deliberate anti-abuse protection, and it's absolute. An agent working through a browser extension or injected JavaScript cannot attach a file to . No amount of cleverness gets around it, because the whole point of the restriction is that no amount of cleverness should.
Which meant our agent could do the interesting 80% and then hand the task back to a human for the tedious 20%. Worse than useless — it created work.
The fix turned out to be a change of vantage point. The restriction applies to code running inside the page. Drive Chromium from outside, over the DevTools Protocol, and setting a file on an input is an ordinary operation — no gesture required, because there's no page-level JavaScript asking for one.
That outside-the-page control comes from Playwright, which is what makes the whole thing possible. agentBrowser is the layer on top: an interface an agent can reason about, credentials it never gets to see, and a single binary you can hand to someone.

Give Claude hands in your own browser — a Chrome extension + MCP server that lets Claude Code drive your real, logged-in Chrome with human-shaped clicks, drags and keystrokes.
stanislawherjan1/gdocs-comments-mcpMCP server for adding inline, range-anchored comments to Google Docs — the one comment operation the Google Docs & Drive APIs can't do. For AI agents (Claude, Cursor, Copilot) that review documents.
bolivestilo/HomekitHomekit gives any AI agent direct, physical control over Apple Home. Flip lights. Lock doors. Read sensors. Through a single open interface.
scrollDynasty/multi-agent-browser-mcpMulti-agent browser MCP runtime for isolated, persistent, parallel Playwright sessions. Run multiple AI agents without shared tabs or browser state.
ZoeLinUTS/MagicTeX-mcpMagicTeX — a LaTeX editor for AI agents (Claude Code): live PDF preview, PDF comments that drive edits, Visual (WYSIWYG) mode, and git-tracked history. No local TeX install.
dhavanikgithub/chartbrew-mcpChartbrew + AI agents. MCP server exposing Chartbrew's documented API: teams, connections, datasets, dashboards, charts, live queries, and secure embedding. TypeScript · stdio · restricted/unrestricte
