MCP Server

Solve CAPTCHAs directly from Claude Desktop, Cursor, Windsurf, and any MCP-compatible tool.

What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI assistants connect to external tools. With the GateSolve MCP server, any MCP-compatible AI tool can solve CAPTCHAs using x402 micropayments.
