MCP connector for Claude

Brazil Public Data

Official Brazilian public data in Claude: IBGE statistics and Banco Central series (inflation, unemployment, GDP, population, wages, house prices, Selic, exchange rates), the dados.gov.br and Banco Central open data catalogues with file previews, and public contracts and open tenders from PNCP. Both keys below are optional; leave them empty to use the keyless sources.

Add it to Claude

1. Create an account and add credits at https://openjack.dev; copy your connection key.
2. In Claude, open Settings → Connectors → Add custom connector and paste https://brazil-public-data.openjack.dev/mcp.
3. Click Connect. You will be asked for the connection key and your Dados abertos do Brasil credentials.

How your data is handled

Your Dados abertos do Brasil credentials are validated once, then stored encrypted with a key that only the token issued to your Claude account can unwrap. Disconnecting the connector in Claude revokes that token. The connector keeps no logs and no cache, and stores none of the data it passes to Claude. Every tool is read-only.
