Unstuck

Human-in-the-loop for browser agents

Your agent got stuck.
A human gets it unstuck.

CAPTCHA, login wall, 2FA code, a page that makes no sense. Unstuck pauses your agent, sends the right person a link, lets them take over the live browser from their phone, and hands control back.

One call where your agent gets stuck

  1. Your agent asks for help. One line: takeover(page), or the MCP tool.
  2. A human gets a link. By email, Slack, Discord, Telegram or push; it opens on any phone.
  3. They solve it live. Tap, type and scroll in the real browser. The agent waits.
  4. The agent carries on. Done hands control back with the result.
import { Unstuck } from 'unstuck';

const unstuck = new Unstuck();
const result = await unstuck.takeover(page, { reason: 'Solve the CAPTCHA' });
if (result.status === 'resolved') {
  // carry on: the human solved it
}
from unstuck import Unstuck

async with Unstuck() as unstuck:
    result = await unstuck.takeover(page, reason="Solve the CAPTCHA")
if result.status == "resolved":
    ...  # carry on: the human solved it
// Claude Desktop, Claude Code or any MCP client
{
  "mcpServers": {
    "unstuck": { "command": "unstuck-engine", "args": ["--mcp", "--open"] }
  }
}
// The agent calls: request_human_takeover({ reason: "Solve the CAPTCHA" })

Private by design

Signed single-use links, one human at a time, and an audit log that never records what was typed.
