Questions
What can the AI do in ActiveCalculator?
The AI can list the calculators in your ActiveCalculator account with their IDs and names, and read the connected account. It does not change anything in ActiveCalculator.
Does the AI see my ActiveCalculator credentials?
No. Your ActiveCalculator credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.
Can I control what the AI is allowed to do?
Yes. You choose which tools are switched on. Both ActiveCalculator tools only read, and every tool call is logged.
Does it work with ChatGPT?
Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.
What does it cost?
HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own ActiveCalculator account.
What can the ActiveCalculator API key access?
The API key has the same permissions as your ActiveCalculator account. In HeyMyApps the AI can only use the tools you switch on, and both of them only read: listing calculators and reading the account.
