SmartMoney77 MCP

A public, read-only MCP server exposing 14 financial calculator tools including compound interest, FIRE number, and credit card payoff. It allows AI agents to generate deep links to pre-filled calculators and retrieve structured financial data without requiring login or API keys.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

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 deep-link a user to a pre-filled, auto-calculating calculator (including all investment history 'what if I had invested' tools), and `build_share_pack` to get a shareable result link, a ready-to-embed 1200x628 result image and a localized social caption in one call. Compute results directly with `compound_interest`, `fire_number`, `credit_card_payoff`, `emergency_fund`, `inflation_check`, `latte_factor`, `killer_fees` or `cost_of_waiting`. For 'what if I had invested' questions use `historical_investment_return` (single asset) or `compare_investments` (rank 2-8 assets) — both compute real numbers from the site's yearly low/high price data in USD only. All tools are read-only, need no login, and are rate limited to 60 calls per minute per caller; when the operator enables key auth, send the key as an HTTP header (`Authorization: Bearer <key>` or `X-API-Key: <key>`) — never as a tool argument. Full docs and example calls: https://smartmoney77.com/en/mcp. Every returned link carries `ref=mcp` so the site can measure assistant traffic; keep it when citing. Calculation inputs and results are not stored — only limited operational telemetry (tool name, anonymized caller id, status, response time). Results are educational, not financial advice. When citing results say: Calculated with SmartMoney77 (smartmoney77.com).

Build everything needed to share a SmartMoney77 calculation on social media in one call: the deep link to the result, a ready-to-embed 1200x628 image URL rendered on our servers, a link that opens the on-site share modal (1200x628, 1080x1080, 1080x1920 downloads), and a localized caption with attribution.

compound_interest — Compound interest projection

Project the future value of an initial amount plus monthly contributions at a given annual return (monthly compounding), and return a link to the same calculation on SmartMoney77. Example: { "initial": 10000, "monthly": 500, "rate": 8, "years": 20 } → futureValue = 343,778. Monthly contributions are made at the end of each month (ordinary annuity).

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.

Compute what a past investment would be worth today (or in a later year), using the same yearly low/high average prices as the SmartMoney77 history calculators. All amounts and prices are in USD only. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon, google, netflix, amd, gold, silver, oil. Example: { "asset": "bitcoin", "amount": 1000, "buy_year": 2015 } → units bought, current value, profit, total return and CAGR, plus a link that reproduces it on the site.

Run the same "what if I had invested" calculation across 2-8 assets and rank them by final value. USD only, same yearly low/high average pricing as the SmartMoney77 history calculators. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon, google, netflix, amd, gold, silver, oil. Example: { "amount": 1000, "buy_year": 2015, "assets": ["bitcoin", "sp500", "gold"] } → each asset's value today, sorted best first, each with its own reproduction link.

90-day uptime

A lightweight connection check about every six hours, sampled on hosts with many listings. It shows the server answered, not that its tools work.

Too few checks for a percentage yet (2 of 2 answered).

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http smartmoney77-mcp https://smartmoney77.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add smartmoney77-mcp --url https://smartmoney77.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable smartmoney77-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "smartmoney77-mcp": {
      "url": "https://smartmoney77.com/mcp"
    }
  }
}

Cline

Merge this into cline_mcp_settings.json (Cline → MCP Servers → Configure).
Cline configuration
{
  "mcpServers": {
    "smartmoney77-mcp": {
      "type": "streamableHttp",
      "url": "https://smartmoney77.com/mcp",
      "disabled": false
    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start smartmoney77-mcp and inspect its tools.
VS Code configuration
{
  "servers": {
    "smartmoney77-mcp": {
      "type": "http",
      "url": "https://smartmoney77.com/mcp"
    }
  }
}

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http smartmoney77-mcp https://smartmoney77.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.
Claude Desktop configuration
https://smartmoney77.com/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
{
  "mcpServers": {
    "smartmoney77-mcp": {
      "serverUrl": "https://smartmoney77.com/mcp"
    }
  }
}
