Connects Claude, Cursor, and other MCP clients to 30+ Brazilian banks through Open Finance Brasil, the central bank regulated API. Exposes read-only tools for account balances, transaction history, credit card bills, investments, and loans across institutions like Itaú, Nubank, Bradesco, and Santander. You can ask natural language questions like "How much did I spend on iFood this month across all cards?" and it pulls real data from multiple banks, categorizes transactions, and generates reports. The API design prevents any write operations, so agents can analyze your finances but never move money. Works as a remote MCP server at api.mcp.ai/banco or via direct REST API if you're building your own integration.
