Wraps Yahoo Finance, FRED, SEC EDGAR, and CoinGecko into five MCP tools: stock quotes, company fundamentals, 800,000+ economic indicators, SEC filing text, and crypto prices. The interesting bit is the payment model. Instead of API keys or subscriptions, it uses x402 micropayments on Base, charging $0.01 per call via automatic USDC transfers from your wallet. You just set an EVM private key and fund it with a dollar or two. Useful when you need financial data in Claude or Cursor without managing yet another API account, and you're comfortable with the crypto payment rails. Caches range from one minute for quotes to 24 hours for filings.
