Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “search_calculators”: Find MonsiTools calculators by keyword (for example 'runway', 'break even', 'roas', 'loan payment'). Returns each match's slug, name, catego.”
“Use “describe_calculator”: Returns a calculator's name, category, formula, input names and page URL, given its slug.”
“Use “calculate”: Runs a MonsiTools calculator on the given inputs and returns the result. Needs a MonsiTools Premium API key, sent as 'Authorization: Bearer.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how MonsiTools Calculators holds up.
gate scanned 3 tools on Oct 5, 2026. A few things are worth a look before you connect.
Operated by MonsiTools Calculators (monsitools.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
This server only exposes public data — no account and no credentials are involved when you connect.
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
If MonsiTools Calculators adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Add one gateway URL to Claude, ChatGPT, or any MCP client. One-time setup, about two minutes.
Choose MonsiTools Calculators in the gate directory. No sign-in needed.
MonsiTools Calculators's tools are live in every AI client you've connected — with rules and logging built in.
