Questions

Before you install.

How do I install the Nubank MCP server?

The npm package @codespar/mcp-nubank is deprecated, so this page shows no install command for it. The registry says: No live endpoint: api.nubank.com.br does not resolve. See https://github.com/codespar/mcp-dev-latam/tree/main/packages/payments/nubank

What can my agent do with Nubank?

Nubank exposes 22 tools for banking. Your agent calls them directly; the full list is above.

How does Nubank authenticate, and how are credentials stored?

Nubank uses OAuth2. Self-hosted, you hold the credentials: the server reads them from its environment variables.

How does Nubank handle upstream API changes?

Every server is versioned independently on npm. This one is deprecated (see the notice above), so the page does not suggest pinning a version.

Is Nubank open source? How do I report a bug?

Yes. Nubank is MIT-licensed and published on npm as @codespar/mcp-nubank, source on GitHub (link in the Details panel). Report issues on the package repository; security issues go to security@codespar.dev, and we respond within 24 hours.
