- Food preparation standards
- Cooking guidelines and methods
- Food safety information
- Recipe standards
- Hygiene and sanitation requirements
Modern Architecture
This server follows current MCP best practices:
- Zod input validation for all tool parameters
- Proper STDIO usage with
console.errorfor logging - Robust error handling with detailed error messages
- Optimized tool definitions with automatic schema conversion
- Comprehensive synonym support for Russian cooking terms
- Clean separation of concerns between parsing, validation, and execution
