Goodbook MCP Server

A modern Model Context Protocol (MCP) server that works exclusively with PDF files containing food service standards and preparation guidelines. Built following MCP best practices with robust input validation and error handling.

Overview

The Goodbook MCP server allows AI assistants to query and retrieve information from food service documentation, including:

• 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.error for 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
