Como funciona? Via Open Finance Brasil (regulado pelo Banco Central). Você conecta sua conta Banco Master com consentimento explícito; a IA lê saldos, extratos, faturas e investimentos. Somente leitura.
A IA pode movimentar dinheiro? Não. 100% leitura — Open Finance não permite movimentação por essa via.
Só funciona com o Banco Master? Este MCP é focado no Banco Master. Para conectar vários bancos de uma vez, use o Banco MCP (api.mcp.ai/banco).
