Perseus Vault — persistent, encrypted memory for AI agents

Perseus Vault gives AI agents persistent, encrypted, deterministic memory, running locally as a Docker-based stdio server with a large tool set.

What you can do

• Provides persistent memory storage for agents, so context can be kept across sessions.
• Encrypts stored memory locally, according to the description.
• Offers deterministic memory behavior and a large set of 173 canonical tools, though the individual tools are not listed in the manifest.
• Runs as a local process on the user's machine over stdio, launched with Docker.

When to use it

Worth considering when an assistant needs memory that survives between sessions and should stay on the user's own machine rather than in a hosted service. Also relevant if you want encrypted, reproducible memory behavior for agent workflows.

Requirements

A local runtime with Docker, since the server is distributed as an OCI image and runs as a local stdio process. No authentication, environment variables or headers are declared. Desktop use only; not available as a web executable.
