CAPTCHA Relay v2

Solve CAPTCHAs by relaying them to a human. Two modes available.

Modes

Screenshot Mode (default) — No infrastructure needed

Grid overlay screenshot → send image to human via Telegram → human replies with cell numbers → inject clicks.

• Zero setup beyond the skill itself. No Tailscale, no tunnels, no relay server.
• Works for any CAPTCHA type (reCAPTCHA, hCaptcha, sliders, text, etc.)
• Uses sharp for image processing + CDP for screenshots and click injection.

node index.js                       # screenshot mode (default)
node index.js --mode screenshot     # explicit
node index.js --screenshot          # legacy alias

const { solveCaptchaScreenshot } = require('./index');
const capture = await solveCaptchaScreenshot({ cdpPort: 18800 });
// capture.imagePath — annotated screenshot to send to human
// capture.prompt — text prompt for the human

Token Relay Mode — Requires network access

Detects CAPTCHA type + sitekey → serves real widget on relay page → human solves natively → token injected via CDP.

• Requires Tailscale or a tunnel (localtunnel/cloudflared) so the human's device can reach the relay server.
• Produces a proper CAPTCHA token — more reliable for reCAPTCHA v2, hCaptcha, Turnstile.
• Best when you have Tailscale already set up.

node index.js --mode relay              # with localtunnel
node index.js --mode relay --no-tunnel  # with Tailscale/LAN

const { solveCaptcha } = require('./index');
const result = await solveCaptcha({ cdpPort: 18800, useTunnel: false });
// result.relayUrl — URL to send to human
// result.token — solved CAPTCHA token

When to Use Each

CLI Flags

Agent Workflow

Screenshot mode (simplest)

1. Call solveCaptchaScreenshot({ cdpPort })
2. Send capture.imagePath to human via message tool with capture.prompt
3. Human replies with cell numbers (e.g. "1,3,5,7")
4. Call injectGridClicks(cdpPort, capture, selectedCells) to click those cells

Relay mode

1. Call solveCaptcha({ useTunnel: false }) (Tailscale) or solveCaptcha() (tunnel)
2. Send result.relayUrl to human via message tool
3. Wait — resolves when human completes the CAPTCHA
4. Token is auto-injected; continue automation

Requirements

• Chrome/Chromium with --remote-debugging-port=18800
• Node.js 18+ and npm install (deps: ws, sharp)
• Relay mode only: Tailscale or internet for tunnel
