Your AI agent is great at writing code. But the moment it needs to check a dashboard, test a UI, or do anything in a browser — it stops and asks you to do it.
I built Hanzi to fix that. It's an open-source MCP server that gives your agent your real signed-in browser.
How it works
One command:
npx hanzi-in-chrome setup
This detects your AI agents (Claude Code, Cursor, Codex, Windsurf), installs the browser extension, and configures everything.
After that, your agent can just use the browser when it needs to. You don't have to tell it — it figures out when browser access would help.
Example: LinkedIn prospecting
I built a skill that automates the whole outreach workflow:
- You give it a goal (networking, sales, hiring)
- It searches LinkedIn in your real browser
- Reads posts and profiles for personalization hooks
- Drafts unique connection notes
- Asks for your approval before sending
No scraping. No headless bot. LinkedIn sees normal user behavior because it is your real browser.
Why not Playwright MCP / Browser Use?
Those tools give your agent a new, empty browser. Every click is a separate tool call. Logging in is a nightmare.
Hanzi gives your agent your actual browser — already logged into everything. One tool call, entire task delegated.

Open source, free. Would love feedback.
