Connects Claude and other MCP clients to 800+ Brazilian banks through Open Finance Brasil, the Central Bank regulated API. You get read-only access to accounts, balances, transactions, credit card bills, investments, and loans across institutions like Nubank, Itaú, Bradesco, and Santander. Ask in natural language to consolidate spending across multiple cards, audit recurring charges, generate portfolio allocation charts, or export monthly statements as CSV. All operations are explicitly read-only with no transfer or payment endpoints. Requires LGPD compliant user consent and works as a remote server at api.mcp.ai/banco. Free tier gives you one connected bank and 10 queries in 24 hours. Paid plans add multi-bank consolidation and direct REST API access for custom integrations.
