Augmented Memory for AI Agents. Persistent memory and stronger recall across sessions and devices.
The MemVault plugin is OpenClaw's long-term memory layer. Context compression is a critical weakness for AI Agents, and MemVault makes it easy to fix.
It gives OpenClaw a durable, cloud-backed memory space that survives:
- new conversations
- process restarts
- device changes
- account linking after first install
The current public repository is focused on the OpenClaw plugin only. OpenClaw is the first production client, and more Agent clients will follow later.
MemVault is designed around a low-friction flow:
- install the plugin
- start using the free tier immediately
- connect your account later with
{/mvstatus}when you need it - keep the same memory space across devices
- Auto-recall before OpenClaw builds the next prompt
- Auto-capture after each agent run, preserving important content in full
- First-run migration for:
MEMORY.mdmemory/*.md- OpenClaw session archives under
active,reset, anddeleted
- Cross-device continuity after account linking
- Explicit tools for search, store, and forget workflows
- Free-tier quota awareness with account-link and upgrade guidance
- Recover project details after long conversations are compressed
- Remember local ports, config paths, deployment notes, and previous decisions
- Continue an OpenClaw project from another device after account linking
- Search old context with semantic recall and explicit keyword-like prompts
Recommended install path:
# Option A (ClawHub)
openclaw plugins install clawhub:@mornlong/openclaw-memvault
# Option B (npm)
openclaw plugins install @mornlong/openclaw-memvault
# Then (required once after either install option)
bash ~/.openclaw/extensions/openclaw-memvault/scripts/setup.sh
openclaw gateway restartVerify in ~60 seconds:
- In OpenClaw chat, run
{/mvstatus}(you should see plan/usage/status). - Tell the agent one project detail (port/path/decision).
- After a few turns (or a restart), ask it to recall that detail.
Note: If ClawHub shows Legacy ZIP under Artifact, the plugin still works.
It only means the package has not shipped a ClawPack artifact yet. See
FAQ.
What happens after install:
- the plugin creates a device identity locally
- the free tier is available immediately
- account linking stays optional until you want cross-device continuity or more capacity
{/mvstatus}shows plan, usage, and connection status
scripts/setup.sh adds the plugin to both plugins.allow and
tools.alsoAllow, so the explicit MemVault tools are visible to the model.
For a step-by-step verification flow, see MemVault Quickstart for OpenClaw.
