A headless browser
- Fresh profile, so every site is logged out
- Two-factor prompts nobody is there to answer
- Trips bot detection precisely because it is one
- Runs somewhere you cannot see it
MCP server
Plug it into the AI you already run,
and hand it a browser that is logged in
Claude Code, Codex, Antigravity, Cursor, Zed: anything fluent in MCP takes the wheel of the same real tab. Headless automation wakes up with amnesia, no session, no cookies, no two-factor state, and a login wall between it and anything worth doing. Browsentic inherits the tab you are already signed into.

The difference that matters
A headless browser wakes up with amnesia
No session, no cookies, no two-factor state, and a login wall between it and anything worth doing. Browsentic inherits the tab you are already signed into.
Browsentic
- Your profile, your sessions, your cookies
- Already through two-factor, because you did it
- A real browser making genuine gestures
- Visible in front of you, stoppable mid-run
How it is built
One registry, so the manifest cannot drift
Any MCP client, one browser
The daemon speaks MCP over stdio, so Claude Code, Codex, Antigravity or anything else that speaks the protocol drives the same real, logged-in browser. Several at once, because one daemon owns the link.
The manifest cannot drift
Tool definitions are generated from the same registry the extension ships. A tool that describes something the browser cannot do is not a bug you can write. It is a build that does not exist.
Create your own action in one file
A module under lib/actions/page/ plus one line in the registry, and it publishes as an MCP tool at the same time. No second place to remember.
Clients
Anything fluent in MCP takes the wheel
One daemon owns the browser link, so several clients can drive the same browser at once. Every step they take surfaces on the side panel timeline, marked external.
