Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
MNEMO_DEFAULT_VAULTOptional | 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_VAULTSOptional | Comma-separated list of vaults this server may reach. Narrow it: a vault left out here cannot be read even by mistake. |
MNEMO_SDK_PORTOptional | Port of the local Mnemosyne OS SDK server the desktop app listens on. |
