Claude, ChatGPT, Cursor or any MCP client connects to it once, and from then on the assistant looks up official records on its own, with every answer backed by the source. **Which clients work?** Any client that speaks MCP over HTTP. Claude and Cursor add it in one click, ChatGPT takes it as a connector, and Perplexity, Gemini CLI, GitHub Copilot, n8n and Make follow the steps on their page. Your own agent can call it with an API key. **How do I sign in?** With your Croma account. The client opens a Croma sign-in the first time and the session is tied to your organization. Agents and scripts can use an API key from the [console](https://platform.usecroma.com/sign-in) instead. **Does it cost extra?** No. The MCP server spends the same credits as the API. Free gives you 5,000 credits a month with no card, a live lookup costs 10 credits and a dataset request costs 1. **What can it look up?** 233 tools over 88 official sources in 6 countries. Judicial cases, company and vehicle registries, background checks, sanctions, procurement, regulations, gazettes and case law, plus web search and extraction. **How current are the answers?** A live lookup queries the official source when the assistant calls it. A dataset request answers from a copy of the whole source that Croma keeps up to date, and every response says how current it is.
