What it does

Nibomo is an open source flashcard app for iPhone, iPad, Mac, Android and the web. It schedules reviews with the FSRS algorithm, works offline on mobile and creates cards with AI. The MCP server at `https://mcp.nibomo.com/mcp` connects Claude, ChatGPT, Codex, Cline and any other MCP client to that data. Sign-in is OAuth in the browser, or an agent key in the `Authorization` header. The server gives an assistant workspaces and cards, and the docs also describe reviews in conversation. Tools include `list_workspaces` and `get_guide`, which serves detailed guides on demand. The repository also ships a skill for publishing open decks to the catalog.

Who it is for. Students and language learners who prepare and review flashcards through an AI assistant.

Good fit when

  • An assistant turns lecture notes into a deck of cards.
  • Before a terminology exam, review runs in conversation with the assistant.
  • You want to list workspaces and find weak cards.
  • A deck is improved with AI: wording fixed and examples added.

Not a fit when

  • You need an offline mode without an account: MCP works through the Nibomo server.
  • You want to stay on Anki: the app differs and this server does not move decks.
  • Data must not go to a cloud.

Example request

List my Nibomo workspaces without changes and suggest which cards to review today.

Limitations

The server is hosted by Nibomo, so you need an account and OAuth sign-in or an agent key. Through it the assistant reads and changes your cards, so grant access only to the workspace you need and back up before bulk edits. Cline needs your own agent key in the `Authorization` header. The mobile apps need iOS or iPadOS 18 or newer, macOS 15 or newer or Android 11 or newer. Tool details and limits are in the docs at `nibomo.com/docs`.

How to disable. Remove the `nibomo` entry from the client MCP settings and revoke the agent key in your Nibomo account. Decks stay in the app.

FAQ

What is the MCP server address?

`https://mcp.nibomo.com/mcp`. Setup is described in the guide at `nibomo.com/docs/mcp-connector/`.

How do I sign in from Cline CLI?

Create an agent key, add a `nibomo` entry with `"type": "streamableHttp"` and an `Authorization: Bearer <key>` header to `cline_mcp_settings.json`, restart Cline and call `list_workspaces`.

Is the app paid?

The README does not state pricing; see the App Store and Google Play pages and the `nibomo.com` site.

Where is the code?

In an open repository under the MIT license: apps, backend and docs. Assistant plugins live in a separate `nibomo-plugins` repository.

Which client works?

Any client with MCP over HTTP: Claude, ChatGPT, Codex, Cline and others. The server address is the same, `https://mcp.nibomo.com/mcp`, and only sign-in differs by client.
