## Why api2mcp4j?
Most MCP integrations force you to:
- Add `@Tool` / `@McpTool` to every method
- Duplicate business logic into a parallel "MCP" code path
- Maintain separate tool descriptions
**api2mcp4j** scans your existing `@RestController` beans and exposes their methods as MCP tools — **zero changes to business code**. Like MyBatis-Plus enhances MyBatis, api2mcp4j enhances Spring AI MCP.
```java
// Your existing controller — unchanged

public class OrderController {
@GetMapping("/orders/{id}")
