OperStackOperStack MCP next to Ahrefs MCP, Semrush MCP and DataForSEO MCP
Ahrefs, Semrush and DataForSEO let Claude, ChatGPT or Cursor pull their SEO data through MCP, mostly on paid plans. OperStack MCP brings a different kind of data into the same assistants: whether AI answers name your site, who they name instead, and how readable your pages are to them. Each server below has its own section with prices, the date we checked them, and when it is the better pick.
OperStack is our product. Each section keeps the prices with the supplier page and the date we checked it.
OperStack vs Ahrefs MCP
OperStack's MCP server is free, needs no account or key, and scores up to 10 pages of any site out of 100 from Claude, ChatGPT or Cursor, using the same code as our free check and Watch. Ahrefs MCP starts on the Lite plan at $129 a month, which includes 5 custom AI prompts; more prompts cost from $50 a month, and the AI Visibility Index from $199. For keyword and backlink queries, Ahrefs MCP is the one built for that.
