Official Extensions

Official Extensions

MedICS ships a set of official extensions maintained by the MedICS Team. Each one is a normal MedICS extension: install it with pip, then open it from the Extensions menu.

For the extension system itself (discovery, extension.json, packaging, publishing), see Extensions.

Installing an official extension

pip install medics-ext-volume-viewer
medics

Then open it from Extensions (or the extension manager dialog). Windowed extensions open as a central tab.

Pinning a version:

pip install "medics-ext-volume-viewer==1.0.0"

---

Updating

pip install --upgrade medics-ext-volume-viewer

Or use Extensions → Extension Manager → Update to update from PyPI, then reload the extension without restarting MedICS.

Extension requirements

Official extensions declare their compatibility in extension.json:

{
  "schema": "medics.extension/1",
  "api_version": 1,
  "name": "Volume Viewer",
  "version": "1.0.0",
  "category": "Visualization",
  "windowed": true,
  "capabilities": ["ui", "workspace"],
  "requires": {
    "medics": ">=2026rc0",
    "sdk": ">=2026.7.7",
    "extensions": []
  }
}

The extension manager checks requires before loading and reports a clear error when the MedICS build is too old.
