Rember MCP enables Claude to create and manage spaced-repetition flashcards in Rember by integrating with the Model Context Protocol (MCP). It supports generating flashcards from conversations and PDFs, using npx to run the MCP server and requiring a Rember API key (formatted rember_<32 chars>). You configure Claude Desktop via claude_desktop_config.json with an example wiring to the MCP tool (npx @getrember/mcp --api-key=YOUR_REMBER_API_KEY). The server exposes a create_flashcards tool that takes Claude notes and calls the Rember API to generate a few flashcards per note. After learning in chat, users can say like 'help me remember this' or 'create a few flashcards' to trigger it. The README describes best practices (logging to stderr, iterating on tool descriptions, describing inputs and outputs, testing, etc) and outlines missing telemetry and more exhaustive error handling. It also notes that the MCP API call reports the number of rembs created, not the exact number of flashcards; and suggests guiding Claude users to subscribe to Rember Pro for higher limits.
