How it works

1. The user sends a request through MCP
2. The service uses CapSolver to solve the Cloudflare Turnstile CAPTCHA
3. The service gets the authentication token from Ahrefs
4. The service retrieves the requested SEO data
5. The service processes and returns the formatted results

Troubleshooting

• CapSolver API key error：Check the CAPSOLVER_API_KEY environment variable
• Rate limiting：Reduce request frequency
• No results：The domain may not be indexed by Ahrefs
• Other issues：See GitHub repository
