Environment

Name	Required	Notes
MNEMO_DEFAULT_VAULT	No	Vault 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_VAULTS	No	Comma-separated list of vaults this server may reach. Narrow it: a vault left out here cannot be read even by mistake.
MNEMO_SDK_PORT	No	Port of the local Mnemosyne OS SDK server the desktop app listens on.
