Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “get_tool_guide”: Discovery helper: returns the standard prompt template, argument template, output-interpretation guide and related resources for one or all.”
“Use “list_calculators”: List every SmartMoney77 calculator with its slug, accepted URL parameters and supported languages/currencies. Call this before build_calcula.”
“Use “build_calculator_link”: Build a deep link to a SmartMoney77 calculator with pre-filled values that auto-calculate on open. Use list_calculators first to find the sl.”
“Use “build_share_pack”: Build everything needed to share a SmartMoney77 calculation on social media in one call: the deep link to the result, a ready-to-embed 1200x.”
Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Financial Calculators holds up.
Operated by Financial Calculators (smartmoney77.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 Financial 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 Financial Calculators in the gate directory. No sign-in needed.
Financial Calculators's tools are live in every AI client you've connected — with rules and logging built in.
