2Captcha MCP
2026 · Tool · Python 3.11+, MCP
An MCP server that opens the whole 2Captcha API to Claude Code: 31 CAPTCHA types and management tools.
2Captcha MCP gives agents the full feature set of the 2Captcha service over stdio: 31 solver types (reCAPTCHA, hCaptcha, Turnstile, FunCaptcha, GeeTest, Yandex Smart Captcha and others), 5 management tools, CRUD for pingback, a webhook event store and a composite “solve and wait” tool — 43 tools in total. Built on the official 2captcha-python SDK (AsyncTwoCaptcha), published on PyPI as twocaptcha-mcp 0.6.1 and prepared for the MCP Registry.
The task
To give an agent a single interface for solving CAPTCHAs and the related operations of the 2Captcha service without manual integration.
