hermes-mnemosyne — Configure, troubleshoot, and operate the Mnemosyne memory provider for Hermes Agent.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Hermes Mnemosyne Memory Provider Mnemosyne is Hermes' primary local-first memory engine — SQLite with vector + FTS5 hybrid search, 19+ tools, auto-consolidation, and a standalone CLI. It's a pip-installed plugin (not a built-in toolset) discovered via `$HERMES_HOME/plugins/mnemosyne/`. ## Quick Reference When comparing memory stacks for the user, use `references/memory-tool-selection-mem0-vs-mnemosyne.md`: Mnemosyne is preferred for Hermes local-first profile memory; Mem0 is the safer productized choice for external/customer-facing apps. For migrations from overlapping stacks such as LCM + built-in memory + gBrain, use `references/memory-stack-migration-pilot.md`. Prefer a staged simplification: preserve LCM, pilot Mnemosyne as the external memory provider, keep the incumbent system read-only for rollback, and retire redundant writers after measured acceptance. | What | How | |---|---| | Check if active | `hermes memory status` or check `memory.provider` in config.yaml | | Memory stats | `mnemosyne stats` (CLI) or `mnemosyne_stats` (tool) | | Manual consolidation | `mnemosyne sleep` (current session) or `mnemosyne sleep --all-sessions` | …

How to install
mdr add atlasomnia/hermes-custom-pack/hermes-mnemosyne@sha256:9650e20e9560433eThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
