For Developers

This repository contains the MCP server implementation for the Rice Stock Data Portal. The server acts as a bridge between Claude Desktop and your deployed Flask application.

Features

• 🔒 Secure Token Storage - Access tokens stored in Claude Desktop configuration
• 💬 Natural Language Queries - Ask questions in plain English
• 📊 Real-time Data - Direct access to your MotherDuck financial database
• 🎓 University Integration - Designed for academic use with email verification
• ⚡ Fast Responses - Leverages existing OpenAI chat integration

Architecture

Claude Desktop → MCP Server → Flask App → MotherDuck Database

The MCP server forwards natural language queries to your Flask app's /chat endpoint, which uses OpenAI to understand the query and generate appropriate SQL.
