Handoff for developers & QA

Stop retyping DevTools1 into your prompt.

You already ship with an AI agent. Handoff feeds it the selector, computed styles, console errors and a screenshot — over MCP, straight from the live page.

One command. Any MCP agent.

Paste one line into Claude Code, Cursor or Codex. From then on your agent reads every pin on every page you review — no export, no copy-paste.

Your agent reads what you'd inspect.

Every pin ships with the exact selector, computed styles, HTML structure, console output, URL and viewport. The agent greps your repo for the selector and lands the fix — first try more often.

The fix comes back on the same wire.

Your agent doesn't just read — it writes back. It fixes the issue in your repo, replies with the commit, and marks the pin resolved. You accept or reopen without leaving the board.

Questions

Which AI agents work?

Any MCP client: Claude Code, Cursor, Codex and more. One HTTP endpoint, standard Bearer auth.

Does Handoff read my codebase?

No. The MCP server only serves your feedback — pins, context, screenshots. Your agent does the fixing in your repo, locally.

Can the agent write back?

Yes — it replies on the pin's thread and marks comments resolved. Your team accepts or reopens each fix.

Can the agent audit a page itself?

Yes — point it at a live URL and it sweeps for real breakage before release: broken images, dead links, console errors, mobile layout breaks. Findings land as pins with screenshots and selectors, marked as AI-created.

Is it really free?

Yes — unlimited reviews and unlimited seats during the public beta. No credit card.
