Run npx -y @codespar/mcp-pix-bcb@0.2.2 and add the config block above to your MCP client: Claude Code, Cursor, Claude Desktop, VS Code, or any MCP-compatible client. No build step, no SDK required.

What can my agent do with Pix BCB?

Pix BCB exposes 18 tools for banking. Your agent calls them directly; the full list is above.

How does Pix BCB authenticate, and how are credentials stored?

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

How does Pix BCB handle upstream API changes?

Every server is versioned independently on npm. The command on this page pins 0.2.2, the version whose tools are listed here; your agent keeps running it until you change the version.

Is Pix BCB open source? How do I report a bug?

Yes. Pix BCB is MIT-licensed and published on npm as @codespar/mcp-pix-bcb, 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.
