Cite42 MCP server

Cite42: AI visibility and SEO data MCP server

Cite42 is an MCP server for AI visibility and SEO data. It works in Claude Code, Codex, Cursor, Claude Desktop and ChatGPT. Your agent can ask the AI models behind ChatGPT, Claude, Perplexity and Gemini, plus Google AI Overviews, a buyer question and see whether the answers mention your brand and which sources they cite. It can also pull keyword search volume, Google Trends, Reddit and YouTube data.

You pay per call from a prepaid USD balance. There is no subscription, and new accounts get $1 of free credit. See pricing.

What you can do with it

Check whether AI answers mention your brand

Ask a buyer question such as "best invoicing software for freelancers" and see which brands each AI model names, in what order, and how often (cite42rankings). Compare your brand with named competitors (cite42compare), or see how the answers describe it (cite42_sentiment).

See which sources AI answers cite

cite42citations lists the URLs the AI models cited for a question and can check whether your page or domain is among them. For the full text, cite42search returns each model's answer with its sources. cite42_recommendations then compares your page with up to two of the cited pages.

Keyword search volume, CPC and competition

cite42keywords returns monthly search volume, CPC and competition for a keyword, with optional related keyword ideas. cite42keywords_batch checks up to 50 keywords in one call.

Google Trends

cite42_trends returns Google Trends interest over time, related and rising queries, and a trend label.

Reddit and YouTube research

cite42reddittrends finds relevant Reddit discussions with cited summaries. cite42youtubetrends finds rising videos, creator angles and title patterns.

Track prompts weekly or monthly

A tracker reruns up to 30 prompts every week or month and keeps the history, so you can see when AI answers start or stop naming your brand.

Run research workflows in one call

Six workflows combine the tools above: content opportunities, topic demand, AI prompt maps, competitor content, AI citation gaps and content briefs.

Requirements

• A Cite42 account, free to create at cite42.dev
• For the API-key setup only: Node.js 22.13 or newer and a Cite42 API key

Installation

Most clients connect to the hosted server at https://mcp.cite42.dev and sign in with your Cite42 account in the browser. There is no API key to create or paste, and nothing to install locally. For CI, servers, or machines without a browser, run this package with an API key instead; see API key setup.

Claude Code

claude mcp add --transport http --scope user cite42 https://mcp.cite42.dev && claude mcp login cite42

Your browser opens to sign in. Then start Claude Code, or restart it if it was already open, and check with /mcp.

Codex CLI

codex mcp add cite42 --url https://mcp.cite42.dev

Codex opens your browser to sign in. If it doesn't, run codex mcp login cite42. Then start a new session.

Cursor

Add to Cursor, or add this under Settings → MCP, or in ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cite42": { "url": "https://mcp.cite42.dev" }
  }
}

Sign in with your Cite42 account when Cursor asks.
