MCP connector for Claude
USA Public Data

Add it to Claude
- Create an account and add credits at https://openjack.dev; copy your connection key.
- In Claude, open Settings → Connectors → Add custom connector and paste
https://usa-public-data.openjack.dev/mcp. - Click Connect. You will be asked for the connection key and your US government open data credentials.
How your data is handled
Your US government open data 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.
