Cursor

Cursor supports MCP servers, so its Composer and agent can solve captchas through the NoCaptchaAI MCP server.

Add the MCP server

Create .cursor/mcp.json in your project (or ~/.cursor/mcp.json for all projects) with the standard mcpServers config:

{
  "mcpServers": {
    "nocaptchaai": {
      "command": "npx",
      "args": ["-y", "nocaptchaai-mcp"],
      "env": {
        "NOCAPTCHAAI_API_KEY": "your_key"
      }
    }
  }
}

Get your_key from the dashboard. Cursor picks up the file automatically; you can confirm the server is connected under Settings → MCP.

Use it

In Composer (or the agent panel), ask in plain language and Cursor will call the solve_captcha tool:

Solve the Turnstile captcha on https://example.com (site key 0x4AAAAAAA...)
and use the token to submit the form.

See the MCP page for the server config and reference implementation.
