🦞 Enhanced OpenClaw with MemOS Plugin

🦞 Your lobster now has a working memory system — choose Cloud or Local to get started.

☁️ Cloud Plugin — Hosted Memory Service

• 72% lower token usage — intelligent memory retrieval instead of loading full chat history
• Multi-agent memory sharing — multi-instance agents share memory via same user_id, automatic context handoff

📌 MemOS: Memory Operating System for AI Agents

MemOS is a Memory Operating System for LLMs and AI agents that unifies store / retrieve / manage for long-term memory, enabling context-aware and personalized interactions with KB, multi-modal, tool memory, and enterprise-grade optimizations built in.

Key Features

• Unified Memory API: A single API to add, retrieve, edit, and delete memory—structured as a graph, inspectable and editable by design, not a black-box embedding store.
• Multi-Modal Memory: Natively supports text, images, tool traces, and personas, retrieved and reasoned together in one memory system.
• Multi-Cube Knowledge Base Management: Manage multiple knowledge bases as composable memory cubes, enabling isolation, controlled sharing, and dynamic composition across users, projects, and agents.
• Asynchronous Ingestion via MemScheduler: Run memory operations asynchronously with millisecond-level latency for production stability under high concurrency.
• Memory Feedback & Correction: Refine memory with natural-language feedback—correcting, supplementing, or replacing existing memories over time.

🖥️ 2、Self-Hosted (Local/Private)

1. Get the repository.

   git clone https://github.com/MemTensor/MemOS.git
   cd MemOS
   pip install -r ./docker/requirements.txt
   

2. Configure docker/.env.example and copy to MemOS/.env
