Good to know

• Community server. An open-source server maintained by the MCP community. Kahubi tests it with live queries before listing it and health-checks it regularly.
• Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
• Your files stay private. Only the search the assistant writes for your question is sent to US Census Bureau.
