Connect an AI assistant to Calculty

Calculty works with AI assistants like ChatGPT and Claude. Once connected, your assistant can find any of our calculators, run them with your numbers, and read our published guides — all without leaving the chat.

Copy this link — you will paste it into your AI assistant in the steps below.

/mcp

  4. 4Review the details, check "I understand and want to continue" (ChatGPT shows this for every custom connector), then click Create.
  5. 5Enable Calculty from the chat composer, then ask ChatGPT to use it — for example, "Use Calculty to work out the mortgage on a $400,000 home."
