Everyone is using Claude for their day to day. Documents, emails, presentations and automations.
But Claude 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 Claude and give it access to more than 200 connections with government data.
What Croma is#
Croma is the connector between Claude and government data. You connect it and Claude 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.
You do not need to know which source you need. You ask in plain English, Claude picks one, queries it and tells you where the answer came from.
It works on Claude's free plan. If you don't have a Croma account yet, create one for free.
Step 1: add the connector#
Click the button below. Claude opens the dialog with the name and URL filled in. Click Continue, then Add.
If the dialog did not open, in a Claude chat open + and go to Connectors, Add connector and Add custom connector. Paste these two values.
