MCP.Pizza Chef: ChronulusAI

Chronulus is a paid outside service, and this add-on is the doorway to it. You describe a situation and a question, hand over text, images or PDFs, and its agents come back with either a forecast over time or a yes-or-no probability, each with a written explanation you can save next to the numbers. Plans start at $7.50 a month with no free tier, and usage is metered in units called chrons. The add-on has not been updated since July 2025, although the service behind it is still active.

chronulus-mcp FAQ

Do I need to pay?

Yes. Chronulus is a subscription with no free tier — plans start at $7.50 a month, and every request spends from a monthly allowance measured in units called chrons.

Do I need an account key?

Yes. You create an account, generate a key in the Chronulus console, and paste it into your assistant's settings file alongside the entry for this add-on.

Can I use this to forecast my own sales?

Yes, within limits. You describe the situation and attach documents, and it reads them and forms a view. It is not fitting a statistical model to a spreadsheet of your own history.

Where do the actual numbers come from?

You supply the scale. The service returns a shape over time, and the save command asks you for the smallest and largest values to expect, so the resulting spreadsheet is that shape stretched between two figures you chose.

Does my material leave my computer?

Yes. The text, images and PDFs you attach are sent to Chronulus to be analyzed, so keep confidential documents out of it unless your organization has cleared the vendor.

Which apps does it work with?

Claude Desktop is the documented one, with three different ways to install it, and it works in anything that accepts a standard MCP entry.

Is it still maintained?

The add-on itself has not changed since July 2025 and its published package dates from March 2025, while the service behind it is still being updated — so expect the add-on to lag the service.

Can it change anything on my computer?

Only by writing files. Two commands save a spreadsheet, a text explanation and an HTML report into a folder you name. Nothing is deleted or moved.

Should I trust a forecast enough to act on it?

Treat it as an informed opinion with its reasoning attached, not a measurement. Read the written explanation that comes with every result before putting the number in front of anyone.
