Connect rating.so to your AI agent

rating.so ships a free MCP server. Add it once, and any MCP-compatible assistant — Claude, Cursor, ChatGPT, VS Code, Codex, Windsurf and more — can look up Ahrefs Domain Rating live. No sign-in required.

What your agent gets

get_domain_rating

{ domain: string }

Look up any domain's Ahrefs DR. Returns the tracked value when we have one, or performs a live lookup on demand.

get_leaderboard

{ limit?: number }

Indie projects tracked on rating.so, ranked by DR, highest first.
