Banco MCP

douglac/banco-mcp

Connects Claude and Cursor to 30+ Brazilian banks through the Banco Central regulated Open Finance system. Exposes 13 read-only tools for querying account balances, transaction history, credit card bills, investment portfolios, and loan contracts across institutions like Itaú, Nubank, Bradesco, and Santander. You authenticate once via magic link, grant consent per bank, then ask natural language questions like "what did I spend on restaurants this month" or "compare my current credit card bill to last month." Runs as a hosted HTTP server at api.mcp.ai/banco, so no local setup required. Built for Brazilian personal finance analysis without touching write operations. Free trial allows 10 queries per day, paid plans start at R$19.90/month for unlimited queries.
