📚 Groq MCP Document Assistant

A high-performance, persistent document management and research assistant powered by Groq and the Model Context Protocol (MCP). This system enables AI-driven document analysis, professional formatting, and long-term memory across sessions.

✨ Key Features

• 💾 Persistent Memory: All documents, edits, and additions are saved to a local db.json file. Your workspace state survives application restarts.
• ⚡ Groq-Powered Intelligence: Utilizes high-speed Llama 3 models for near-instant document summarization and complex formatting.
• 🛡️ Safety Circuit Breaker: Built-in protection against infinite tool-calling loops. The assistant automatically stops and asks for help after 10 autonomous steps.
• 🪄 Smart Formatting: Professional Markdown reformatting with a dedicated /format prompt that preserves original data while elevating readability.
• 🔍 Resource Integration: Mention documents in chat using the @filename syntax to automatically inject their content into the AI's context.

🏗️ Architecture

• main.py: The entry point that orchestrates the MCP clients and the Groq service.
• mcp_server.py: The core document server providing tools and prompts. Uses LocalStorage for db.json persistence.
• core/chat.py: Handles the autonomous loop and the 10-step circuit breaker.
• core/groq.py: Manages communication with Groq, including "Tool-Aware Trimming" to prevent history corruption.
