Flash gives an AI client access to decks through MCP. The client can add cards, run study sessions, and ask questions from a deck, while the server schedules future reviews with FSRS. It is shipped as a single Rust binary and supports importing and exporting Anki .apkg decks.
For a self-hosted setup, run the server in Docker and keep its data in the flash-data volume. The MCP endpoint is /mcp; exposing it beyond the local machine requires a TLS reverse proxy and FLASH_BASE_URL. The hosted version can also build cards from files and grade spoken answers. Back up the volume before upgrading, since upgrades move forward only.
