No. 1102tools is independent and built by a federal contracting officer. No federal agency runs an official production MCP server for Federal Register (checked October 8, 2026).

Can anyone see what I search?
No. Searches aren't logged or saved, and IP addresses aren't kept. When the hosted server calls a government site, the request comes from 1102tools, not from you. Your AI app handles the conversation under its own privacy policy.
