Kafkai

Connect Claude or ChatGPT to real SEO data — keywords, backlinks and competitors for any site

MCP plugin for your own AI

Installs inside Claude, ChatGPT, Claude Code or a custom agent, so you keep asking questions in the assistant you already pay for and the answers come back with real data attached.

Real keyword and backlink data

Returns the keywords a site ranks for with position and monthly search volume, plus link intersects showing sites that link to your competitors but not to you.

4C gap analysis

Sorts the keyword gap between you and your competitors into Compete, Catch-up, Consolidate and Complement recommendations. Registered with the Japan Patent Office as Patent No. 7701764.

Your own Search Console and analytics

Once you verify a domain, your AI can read your Search Console clicks and analytics data — numbers your competitors cannot see.

Strengths & Pros

+Answers come from real search data instead of the model's guesses, so both you and your competitors get different quality of output
+No monthly subscription — you pay per question, so you can research a site once and read the results for weeks
+Works inside the AI you already use, so there is no separate dashboard to learn
