Journey fit
Captcha integration is built when you wire scrapers, test flows, or automation—not when you distribute marketing or monitor production errors. A third-party CAPTCHA API wrapper is a classic build-time integration, so the canonical placement is build → integrations.
How it compares
Full 2Captcha API MCP shim—not an open-source OCR captcha skill or a browser-only extension.
Common Questions / FAQ
Who is 2Captcha MCP for?
Solo builders and automation authors using Claude Code who already pay for 2Captcha and want every major solver and management call available as MCP tools.
When should I use 2Captcha MCP?
Use it while building integrations when target sites gate logins or forms with CAPTCHAs your Playwright or API flow must pass under agent control.
How do I add 2Captcha MCP to my agent?
Set 2Captcha_API_KEY, run twocaptcha-mcp via uvx or PyPI stdio transport, add the server to your MCP config, restart Claude Code or your client, then call the solver or management tools.
