This is a Spring Boot REST template, not an MCP server. The single tool 'hello' is a Spring REST endpoint, not an MCP tool definition. No MCP protocol implementation is visible. The tool has a trivial description ('VCSOP Java Template Hello World API'), no input schema (empty {}), and no parameter documentation. The codebase contains zero MCP-specific code: no tool registration, no MCP transport layer, no schema definitions, and no error handling patterns. This appears to be a misclassified submission, it is a basic Spring Boot web app, not an MCP server.

• Implement MCP protocol: add MCP transport layer (HTTP/SSE or STDIO), tool registration with proper schemas, and request/response handling per the MCP spec
• Define explicit input and output schemas for the 'hello' tool using JSON Schema with typed fields and descriptions
• Expand tool description to 50 - 200 characters explaining purpose, when to call it, and what it returns (e.g., 'Returns a greeting message. Use to verify the service is running.')
• Add structured error responses with error codes, messages, and recovery hints (e.g., 'Service unavailable. Retry in 30 seconds.')
• Document the BaseResponse output schema with field types and meanings so LLMs understand the response structure
