Run it locally

Release access for v2.23.2 is temporarily paused.

Perseus Vault v2.23.2 release assets are unavailable while repository access is being restored. The local data boundary and API reference remain documented; use the status page before installing.

Repository and release links are temporarily unavailable. We removed dead links while source access is being restored. See the source access status →

Storage and keys

Know what is encrypted.

Fresh installs encrypt stored entity bodies with AES-256-GCM. The FTS5 search index and metadata stay in plaintext. You control the key file, file permissions, backups, and disk encryption.

Vault security model access status →
Default connection
Local MCP stdio. No network or telemetry is required.
Optional connection
HTTP/SSE is opt-in and must be authenticated and protected by the deployment.
Search index
FTS5 content and metadata need OS-level disk protection when file opacity matters.
