Build a Full Backend with Cursor and Xano

In this walkthrough, we use Cursor alongside the Xano CLI and Developer MCP to build a Customer 360 backend for an agentic banking system — including tables, relationships, business logic, and a decisioning layer from a single prompt — then generate a matching frontend using Cursor's full backend context.

What's covered

• Installing the Xano Developer MCP in Cursor with one click
• Installing the XanoScript Language Server for real-time syntax validation
• Setting up the Xano CLI and authenticating your workspace
• Prompting Cursor to build a Customer 360 API — customers, accounts, transactions, support cases, products, risk flags, interaction history, and agent audit logs
• Using the Developer MCP to write and validate XanoScript automatically as Cursor builds
• Pushing to a Xano sandbox to validate business logic before production
• Publishing to a branch and promoting to a live production environment
• Adding a decisioning layer that evaluates customer profiles and returns recommended next actions for a banking agent
• Generating a frontend in Cursor with full API and business logic context already loaded

The Developer MCP lets Cursor write and validate XanoScript as it works, so the backend it generates is production-ready — not a throwaway prototype. Once the APIs and business logic are live, Cursor already has full context to build a matching frontend.
