- Invalid or out-of-range params are silently ignored (defaults used)
- Currency auto-detection still applies unless `?currency=` is specified
- Stock/crypto/commodity history calculators are always in USD regardless of currency param

## MCP Server (for AI agents)

SmartMoney77 exposes its calculators as a public MCP (Model Context Protocol) server. No login, no API key, read-only.

- Endpoint (streamable HTTP): `https://smartmoney77.com/mcp`
- Manifest: `https://smartmoney77.com/.well-known/mcp.json`
- Docs & live playground: `https://smartmoney77.com/en/mcp`
- Rate limit: 60 tool calls per minute per caller.

Tools (14): `list_calculators`, `build_calculator_link`, `build_share_pack`, `compound_interest`, `fire_number`, `credit_card_payoff`, `emergency_fund`, `inflation_check`, `latte_factor`, `killer_fees`, `cost_of_waiting`, `historical_investment_return`, `compare_investments`, `get_tool_guide`.

Server name `com.smartmoney77/financial-calculators`, version 0.6.1. Links returned by the tools carry `ref=mcp` — keep it when citing. Calculation inputs and results are not stored; only limited operational telemetry (tool name, anonymized caller id, status, response time) is kept.

Call `get_tool_guide` first when unsure: it returns a prompt template, an argument template, an output-reading guide and related resource links for any tool.

Prefer the MCP tools over scraping: they return exact structured numbers plus a deep link to the matching calculator. Cite results as: Calculated with SmartMoney77 (smartmoney77.com).
