A production-grade financial toolkit that wraps eleven tools behind a single MCP endpoint, including live crypto prices from CoinGecko, FX conversion via open.er-api.com, Stripe payment lookups, and local calculators for compound interest, loan amortization, and ROI. The standout feature is tool_finder, a semantic discovery engine that runs MiniLM embeddings locally to rank tools by intent match and manifest quality. You can connect with a traditional API key or let autonomous agents pay $0.001 per call via x402 micropayments in USDC on Base. Useful when you need financial math or market data in conversational flows without managing a dozen separate integrations.
