Augmented Memory for AI Agents. Persistent memory and stronger recall across sessions and devices.

Overview

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.

User Flow

MemVault is designed around a low-friction flow:

1. install the plugin
2. start using the free tier immediately
3. connect your account later with {/mvstatus} when you need it
4. keep the same memory space across devices

What The Plugin Does

• Auto-recall before OpenClaw builds the next prompt
• Auto-capture after each agent run, preserving important content in full
• First-run migration for:
  • MEMORY.md
  • memory/*.md
  • OpenClaw session archives under active, reset, and deleted
• Cross-device continuity after account linking
• Explicit tools for search, store, and forget workflows
• Free-tier quota awareness with account-link and upgrade guidance

Installation

Recommended install path:

openclaw plugins install @mornlong/openclaw-memvault
bash ~/.openclaw/extensions/openclaw-memvault/scripts/setup.sh
openclaw gateway restart

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.

Commands And Tools

Slash command

• {/mvstatus}: show plan, usage, and current account connection state

Agent tools

• memvault_search
• memvault_store
• memvault_forget

Defaults

The plugin is optimized for install-first usage:

Option	Default	Purpose
apiUrl	https://api.mv.mornlong.com:8443	MemVault API endpoint
autoRecall	true	Recall memory before replies
autoCapture	true	Capture important conversation turns
maxRecallResults	5	Maximum recalled memories per turn
recallTimeoutMs	3500	Skip recall if lookup becomes too slow
scoreThreshold	0.4	Minimum similarity score
debug	false	Verbose plugin logging

Environment variable fallback:

Variable	Maps to
MEMVAULT_API_URL	apiUrl

Repository Layout

dist/ stays in the repository on purpose so local-path OpenClaw installs do not depend on a TypeScript build step.

Development

npm ci
npm run build
npm test
