Best Finance Software for Cursor

OpenBudget connects your bank and investment accounts to Claude, ChatGPT, and any other AI assistant through MCP, so you can ask real questions about your money and get real answers, not generic advice. Once connected, every transaction and every holding syncs automatically. Ask about your spending, your net worth, your dividend income, or what you'd owe in capital gains tax before you sell, and Claude answers from your actual accounts instead of guessing. The connection is read-only. OpenBudget can see your data but can never move money, place a trade, or change anything in your accounts. It works with whichever AI client you already use, so you're not locked into one app to get value from it. Plans start at $5/month with a 7-day free trial.

CommodityPriceAPI is a developer-first REST API delivering real-time and historical price data for 170+ commodities, including gold, silver, WTI and Brent crude, natural gas, and agricultural assets. Prices are aggregated from exchange-grade sources and refreshed second-by-second, with rates available in 150+ quote currencies. Five predictable endpoints cover the full workflow: latest rates, historical rates back to January 1990, time-series data, fluctuation calculations, and a symbols reference, all authenticated with a single API key and returned as clean JSON. No SDK is required, integration typically takes under 5 minutes. The platform includes an official MCP server, letting AI assistants like Claude and Cursor query live and historical commodity data directly. Built for fintech dashboards, trading tools, agri-tech platforms, and energy monitoring, with 99.97% uptime and sub-80ms average response times.
