FAQ
How do I add an app?
Each app is a remote MCP server over streamable HTTP. Add https://gpt-billsprig.cybermaxtools.com/mcp (or gpt-ledgermoor, gpt-recapwren, gpt-dutyfinch, gpt-kevscope) as a connector in ChatGPT or any MCP client.
Is it free?
Yes. The tools are fully usable free, with a fair-use limit of 120 tool calls a minute per app, shared by everyone.
What is stored?
Nothing. Generated PDF, Excel and CSV files live inside signed, private download links that expire after 7 days.
Do I need an account?
No. If you already have a CyberMax key for Kevscope, Dutyfinch or Ledgermoor you can optionally sign in to use your own plan's limits.
Where does the data come from?
Tariffs come from the official USITC Harmonized Tariff Schedule; CVE checks use CISA's Known Exploited Vulnerabilities catalog and FIRST EPSS.
