Financial Calculators is a Model Context Protocol (MCP) server: Financial calculators over MCP: compound interest, FIRE, historical returns, deep links, 6 languages. In practice that means any MCP-compatible AI assistant can call Financial Calculators's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://smartmoney77.com/mcp and you're connected, with nothing to install locally. The current release is v0.6.0.
Financial Calculators is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
