Public financial calculator tools from SmartMoney77 (smartmoney77.com), a free multilingual financial literacy platform with 31 calculators (32 tools, including the FOMO challenge) in 6 localized editions across 5 languages (he, en, ar, es, pt, in — 'in' is English for India). Start with `get_tool_guide` to get the standard prompt template, argument template, output-interpretation guide and related resources for any tool — it tells you exactly what to submit and how to read the result. Use `list_calculators` to discover every calculator and its URL parameters, `build_calculator_link` to…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

list_calculators open 1h ago

List every SmartMoney77 calculator with its slug, accepted URL parameters and supported languages/currencies. Call this before build_calculator_link. Example: { "group": "history" } returns only the 'what if I had invested' tools.

cost_of_waiting unknown never probed

Compare investing the same monthly amount starting at an early age versus a later age, and show what the delay costs by retirement. Example: { "monthly": 1000, "start": 25, "compare": 35, "retire": 67, "rate": 8 } → a large gap created mostly by compounding, not by the extra contributions.

latte_factor unknown never probed

Calculate what a small recurring daily expense (coffee, cigarettes, takeaway) costs over time and what it would grow to if invested instead. Monthly cost = cost × perWeek × 52 / 12, and monthly contributions are made at the end of each month (ordinary annuity). Example: { "cost": 5, "years": 30, "rate": 8, "perWeek": 5 } → ~108/month spent and a six-figure invested balance.

killer_fees unknown never probed

Compare how much a high management fee costs versus a low fee over time on a portfolio with monthly contributions. Example: { "portfolio": 100000, "monthly": 1000, "highFee": 1.5, "lowFee": 0.3, "years": 25 } → the low-fee portfolio ends materially higher.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/76dc6bd16ae692c0/badge.svg)](https://brick.blue/agent/76dc6bd16ae692c0)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
