FAQ

Frequently asked.

What is an MCP server?+
The Model Context Protocol is an open standard that lets AI agents call tools from external servers. CalmSEO implements MCP over HTTP, so agents like Claude and Cursor can call SEO tools the same way they call filesystem or git tools.
Which agents are supported?+
Anything that speaks MCP: Claude Desktop, Claude Code, Cursor, Windsurf, Codex, Continue, Cline, and Zed.
How does this compare to Ahrefs or Semrush?+
CalmSEO is not a dashboard. It exposes the SEO primitives an AI agent or app needs (SERPs, volume, ranked keywords, audits, GSC) through MCP and a REST API. See the Ahrefs MCP alternative and Semrush MCP alternative pages for a side-by-side.
Can I use CalmSEO without an AI agent?+
Yes. The same SEO tools are available over a plain REST API. Create an API key and call SERPs, keyword data, audits, and Search Console from your own code, scripts, or scheduled jobs. MCP and the REST API share one account and one credit pool.
How do credits work?+
Each paid tool reserves a fixed number of credits before the upstream call. If the upstream call fails, the reservation is released. Cached responses do not deduct credits. Google Search Console tools are free on every plan.
Where does the data come from?+
Two sources. Your own Google Search Console (via OAuth) for clicks, impressions, CTR, and position on your sites. DataForSEO for live SERPs, keyword volumes, ranked keywords, and on-page audits. We cache responses and reserve credits in front of the paid endpoints.
Can I cancel any time?+
Yes. Stripe-backed monthly billing. Unused credits expire at the end of each cycle.
