Environment variables
  • MNEMO_DEFAULT_VAULTVault used when a call does not name one. The vaults are the user's own domains of memory (code, notes, journal); nothing outside the granted list is reachable.
  • MNEMO_VAULTSComma-separated list of vaults this server may reach. Narrow it: a vault left out here cannot be read even by mistake.
  • MNEMO_SDK_PORTPort of the local Mnemosyne OS SDK server the desktop app listens on.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
