MCP Server Flashcard Lessons

Learn practical lessons from building an open‑source MCP server that creates spaced‑repetition flashcards, covering prompt design, tool‑call handling, and systematic testing.

Overview

We recently built and launched an MCP server for rember.com that let’s you create spaced repetition flashcards from you LM chats. Building a MCP server is easy, building a great one is hard. In this demo we share a few lessons learned along the way, including: prompt engineering for the tool description, strategic use of the tool call response, and testing. The MCP server is open source, and the demo will be supported with code.
