You can use the $10 per month hosted plan with usage credits or self-host it with your own DataForSEO API key.

How we checked it
Checked the every-app/open-seo repo (MIT, about 23,900 stars, release v0.1.13 on 2026-10-14), OpenSEO's MCP docs and pricing page, and its Claude connectors directory listing; the hosted endpoint answers with an OAuth challenge.
