captcha.cc Human Verification

Integrates captcha.cc's human verification service into your Claude workflow. Exposes challenge creation and verification endpoints that match the captcha.cc API structure: generate visual or audio CAPTCHAs with your site key, collect user responses, and verify proof tokens against their backend. Useful when you need to add CAPTCHA gates to automation workflows or validate user interactions before proceeding with sensitive operations. The server wraps their standard direct flow where the browser creates challenges and your backend calls siteverify with the secret key. Works over streamable HTTP, so you can drop it into existing MCP setups without additional transport configuration.
