Question 1

Does Spring MCP Bridge include authentication?

Accepted Answer

No, it does not currently include authentication. If your Spring Boot API requires authentication, you need to modify the handler code to include the appropriate headers or tokens.

Question 2

What Spring Boot features are supported?

Accepted Answer

It supports REST controllers (`@RestController`, `@Controller`), HTTP methods (`@GetMapping`, `@PostMapping`, `@PutMapping`, `@DeleteMapping`, `@PatchMapping`), request parameters (`@RequestParam`), path variables (`@PathVariable`), request bodies (`@RequestBody`), and Java models/DTOs.

Question 3

How does Spring MCP Bridge work?

Accepted Answer

It scans Java source code to extract metadata from REST endpoints, converts Java types to JSON Schema types, generates a FastAPI application that maps MCP calls to Spring REST calls, and forwards requests from the MCP client to the Spring Boot application.

Question 4

What credentials does it need?

Accepted Answer

It reads `SPRING_BASE_URL` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
