Open-Source Licenses and Source Availability

AnkiMCP is built on open-source software. This page credits those projects, lists their licenses, and shows you where to get the source code.

We are grateful to the maintainers of every project below. Without them, AnkiMCP would not exist.

The hosted Anki service

Each hosted instance runs the real Anki desktop app — unmodified, from the official release — with two AnkiMCP add-ons loaded into it. Anki is licensed under the AGPL-3.0-or-later. Because you interact with this combination over the network, its complete source code is available:

The remote desktop (VNC) viewer

The remote desktop viewer in your browser is the Kasm noVNC web client, shipped unmodified. Its source lives at github.com/kasmtech/noVNC and it combines a few licenses:

PartLicense
JavaScript client codeMPL-2.0
HTML and CSSBSD-2-Clause
Orbitron fontSIL OFL 1.1
pako (compression)MIT

On the server side, the viewer connects to the KasmVNC server (GPL-2.0, github.com/kasmtech/KasmVNC) running inside your hosted instance.

Inside the hosted instance

More open-source software runs on our servers to power each hosted instance. We want to acknowledge it too:

The web dashboard

The AnkiMCP dashboard is built with open-source libraries too. Almost all of them use the MIT, Apache-2.0, BSD, or ISC license — among them React, Radix UI, TanStack Table, KaTeX, wavesurfer.js, and Lucide icons.

Two components deserve a specific mention:

  • @breezystack/lamejs (LGPL-3.0) — encodes MP3 audio directly in your browser. Source: github.com/gideonstele/lamejs
  • Material Design Icons font (Apache-2.0) — the community-maintained icon font by Pictogrammers, used in parts of the interface.

Getting the source

AnkiMCP’s own open-source code is public on GitHub:

  • CLI server (MIT) — the command-line MCP server you can run yourself
  • AnkiMCP add-on (AGPL-3.0-or-later) — the add-on that runs inside Anki
  • CI Buddy add-on (AGPL-3.0-or-later) — the helper add-on used in hosted instances
  • headless-anki (AGPL-3.0) — the base image for hosted Anki instances

The hosted platform itself — the dashboard, tunnel service, and account system — is AnkiMCP’s own service code. The open-source components of AnkiMCP are the repositories linked above.

Want the exact source code for a specific hosted version? Email support@ankimcp.ai or ask on the community forum, and we’ll point you to it.
