Journey fit
Banking connectors belong on the Build shelf under integrations because you install them while wiring product or ops automation to live Brazilian payment rails. Nubank is a third-party financial API exposed through stdio MCP, matching the integrations subphase for external service hooks.
How it compares
Open Finance MCP bridge for one neobank, not a multi-bank aggregator skill.
