Overview

AI-generated overview

Lets an assistant search 769 business, finance and SaaS calculators and run them with exact formulas.

What it does
Exposes a catalog of 769 business, finance and SaaS calculators. An assistant can search the catalog and describe individual calculators, and can run a calculation to get a result based on the calculator's exact formula. Search and describe work without credentials; running a calculation requires a premium API key.
When to use it
Useful when an assistant needs reliable, formula-based business or finance figures rather than estimating them itself, for example loan, pricing, or SaaS metric calculations. Worth adding if such calculations come up often enough to justify a remote dependency.
Requirements
A remote MCP endpoint at over streamable HTTP; nothing to install locally. Search and describe need no credentials. The calculate tool needs an Authorization header carrying a bearer token with a MonsiTools Premium API key (mt_live_...). Network access to the provider is required.
Before you install
The calculate tool requires a MonsiTools Premium API key sent as a bearer token in the Authorization header; treat it as a secret and avoid exposing it in logs or shared configuration. Calculations are sent to the provider's remote service, so inputs leave the user's machine. The key is only needed for calculate, so search and describe can be used without it.
