Everyone is using ChatGPT for their day to day. Documents, emails, presentations and automations.

But ChatGPT can be much better. By default it only connects to your tools and to the internet. It has no access to government data, like company registries, court dockets, sanctions lists or what a company reports to the SEC.

Those are the same records a lawyer, an investor, a finance professional or a compliance officer needs every day.

Today we show you how to connect Croma to ChatGPT and give it access to more than 200 connections with government data.

## What Croma is

Croma is the connector between ChatGPT and government data. You connect it and ChatGPT gets access to more than 80 official sources across six countries. The United States, Brazil, Mexico, Colombia, Peru and El Salvador. Companies, court dockets, sanctions, public procurement, financial statements and laws, all of them [here](/mcp).

You do not need to know which source you need. You ask in plain English, ChatGPT picks one, queries it and tells you where the answer came from.

It needs a paid ChatGPT plan. If you don't have a Croma account yet, [create one for free](https://platform.usecroma.com/sign-up).

## Step 1: add the connection

Click the button below. In *Plugins*, click *Add*, then *Create MCP app*. Paste these two values, tick *I understand and want to continue* and click *Create*.

If it answers with Space Exploration Technologies and what it raised in each round, you are done. If you do not see the tools, open another chat.
