Cite42 — Claude Code MCP server: AI visibility and SEO data
Gives your agent AI visibility and SEO data: which models mention your brand, what sources they cite, keyword volume and trends. Pay per call.
claude mcp add --transport http mcp https://mcp.cite42.devWhat Cite42 does
Cite42 is an MCP server that feeds an agent AI visibility data, also called generative engine optimization, alongside SEO metrics. Ask it a buyer question and it shows whether ChatGPT, Claude, Perplexity and Gemini name your brand, in what order, and which sources they cite. Other tools put your brand next to named competitors and show how the answers describe it.
Beyond AI visibility, the server returns monthly keyword volume with CPC and competition, Google Trends interest, Reddit discussions and YouTube videos. Trackers rerun up to 30 prompts weekly or monthly and keep the history, so you can spot when models start or stop naming your brand. Six workflows bundle these tools into a single call.
Most clients point at the hosted server https://mcp.cite42.dev and sign in through a browser; nothing is installed locally. CI and browserless machines need an API key plus Node.js 22.13 or newer. Calls are billed against a prepaid USD balance — no subscription — and new accounts start with $1 of credit.
