FlashCardsMCP

# FlashCardsMCP Copilot Instructions - This is a FastMCP (Model Context Protocol) server for flash card projects, using OpenAI embeddings and SQLite. - All project and card data is stored in SQLite, with semantic search via OpenAI embeddings. - All API/tool functions return dicts with a 'type' field: 'project' or 'card'. - Never return binary embedding data in API responses. - Project and card creation tools return the full object, not just the id. - Use the following tool signatures and behaviors: - All tools should raise ValueError for not found or empty results. - See README.md for user-facing features and usage.
