Add examples/playwright/solve-recaptcha-audio.mjs — annotated Playwright
recipe for solving reCAPTCHA v2 via the audio challenge.
- Spawns MCP server, applies stealth fingerprint (same seed as vision example)
- Checks solver_info.capabilities.audio before launching browser; exits cleanly
on unsupported provider with a clear message
- Clicks the anchor iframe checkbox, switches to audio challenge if image grid
shown first, reads MP3 URL via .rc-audiochallenge-tdownload-link / #audio-source
- Passes URL directly to solve_audio_captcha (server fetches + decodes)
- Types transcription into #audio-response, clicks #recaptcha-verify-button
- Reads g-recaptcha-response from host page; logs outcome, exits 0 on no token
(headless environments commonly produce no token — documented in comments)
- node --check passes; no Go changes
