Flashcards Open Source App

What Flashcards Open Source App does

Flashcards Open Source App connects MCP-compatible AI assistants with Nibomo, an open-source flashcard application. Nibomo supports study on iPhone, iPad, Mac, Android, and the web, while the MCP connector provides an interface for assistants to work with its learning content.

The server focuses on two types of operations: reading existing flashcards and decks, and writing changes to them. The read and write capabilities are exposed as separate MCP tool groups. This separation gives an assistant a clear way to inspect study material before creating or changing content.

Use it when flashcard content is part of an AI-assisted workflow, such as preparing an exam deck, adding vocabulary, or refining cards about technical subjects and facts.

How it works

The MCP service is available through a hosted streamable HTTP endpoint:

https://mcp.nibomo.com/mcp

An MCP client connects to that URL and presents the available read and write tools to an AI assistant. The assistant can then retrieve flashcards or decks from Nibomo and send supported write operations back through MCP.

The resulting content can be used in Nibomo's broader study workflow. The application supports offline study on mobile devices and uses FSRS spaced repetition for reviews, but those app-level features are separate from the MCP connection.

Setup and configuration

Configure the MCP client to use the hosted endpoint above as a streamable HTTP server. The repository includes an MCP client setup guide at docs/mcp-connector.md, and the project also links to a public MCP connector guide at https://nibomo.com/docs/mcp-connector/.

No local package installation or runtime setup is required for the hosted endpoint. After the client is configured, the assistant can use the server's read and write tools within an MCP session.

Tools and capabilities

• Read flashcards and decks from Nibomo.
• Write flashcard and deck data through separate MCP tools.
• Connect AI assistants to Nibomo over MCP.
• Support study-content workflows for exams, vocabulary, technical terms, and factual recall.
• Use Nibomo content across its supported iPhone, iPad, Mac, Android, and web applications.

Limitations and notes

The MCP connector is an interface to Nibomo's flashcard and deck content; it is not the complete Nibomo study application. Features such as FSRS review scheduling and offline mobile study belong to the application itself.

The service is designed for MCP-compatible AI assistants. Client configuration details are maintained in the project's MCP connector documentation. The project is released under the MIT license.
