Works with Claude Desktop, Claude Code, Cursor, VS Code, and any Model Context Protocol client. Powered by CapSkip — a that runs on your own machine, licensed once rather than billed per solve. An AI agent driving a browser hits a captcha and stops. This server gives it ten tools so it can read the sitekey, solve the challenge, and carry on — without a human stepping in and without a per-solve API bill. CapSkip runs as a desktop app exposing a captcha-solving HTTP API on 127.0.0.1:8080. capskip-mcp is a thin translation layer over that API: the fifth official CapSkip client, alongside the Python, Node.js, PHP and .NET SDKs. There is no tool for them and capskip_solve_recaptcha will not work on one. hCaptcha is the easiest to misidentify since it also carries a data-sitekey — check for class="h-captcha" or a js.hcaptcha.com script first. Try them against live widgets on the captcha demo pages. Download and run the CapSkip desktop app from capskip.com.
