Error Response And Exception Handling Validation

via “error handling and validation with structured error responses”

Provide a scalable and efficient server-side application framework to implement the Model Context Protocol (MCP) using Node.js and NestJS. Enable seamless integration of LLMs with external data and tools through a robust and maintainable server architecture. Facilitate rapid development and deployme

Unique: Implements error handling through NestJS exception filters that automatically catch handler exceptions and format them as protocol-compliant MCP error responses, with support for custom validators and error codes

vs others: More consistent than manual error handling because all exceptions are caught and formatted automatically, and more informative than generic error messages because validation errors include detailed field-level information
