AI agents

MSYS comes with an MCP server and a command line, so AI apps on your computer — Claude, Cursor, VS Code, Codex, Gemini CLI — can read the same graphs and alerts you see. Connect one in Settings > AI agents. Signing in and the AI settings always wait for your Yes in the MSYS window.

How to install

  1. Download the file for your system above.
  2. In the app, use your purchase email and the 16-character signature from your purchase email, or a licence key. The website uses a separate 6-digit sign-in code. Already running another MareArts app? There is nothing to sign in to.
  3. Install it:
    • Linux — double-click the .deb and press Install.
    • macOS — open the .dmg and drag the app to Applications.
    • Windows — run the downloaded .msi and follow its steps (if a SmartScreen notice appears, click “More info → Run anyway”).
  4. The app offers a newer version when one is published, and installs public releases by itself while its window is put away.
