MCP Quickstart

Connect Cite42 to Claude Code, Claude Desktop, Codex CLI, Codex Desktop, Cursor, Claude.ai, or ChatGPT over MCP. Create an account, connect your app, and ask in plain English. Your agent queries ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews and hands back structured JSON.

Pick your environment

The fastest path is MCP: one setup and your agent can call the API directly. Choose Claude Code, Claude Desktop, Codex CLI, Codex Desktop, Cursor, Claude.ai, or ChatGPT. For environments that don't speak MCP, use the REST API.

  1. Get your API key

    • Create a Cite42 account or log in.

    • Open the API keys page and create a key. It's shown once, so copy it now; you'll paste it into the command below as CITE42_API_KEY.

  2. Add the MCP server

    Run this in your terminal. Swap in your key, or set it as an env var.

    → registers 15 tools · ~15 seconds

  3. Restart Claude Code

    Quit and reopen so it picks up the new server. Verify with /mcp; you should see cite42 listed.

  4. Ask in natural language

    No code required. Your agent picks the right tool and fans out across the models.
