Memory OS AI

Adaptive memory system for AI agents — universal MCP server for Claude Code, Codex CLI, VS Code Copilot, ChatGPT, and any MCP-compatible client.

What's new in 4.0 — Memory OS v4

pip install memory-os-ai now ships two engines:

memory-os-ai --selfcheck                         # exercise every tool once
memory-os-ai                                     # stdio MCP server
memory-os-ai --transport http --port 8765 --warm # one shared HTTP server for all clients

Data lives in MEMORY_V4_DIR (default ~/.memory-os-v4). Existing v3 memories can be imported with the memory_migrate_v3 tool. LoCoMo Recall@10 (model-free benchmark, v4/bench): v3 0.175 → v4 0.538 with production defaults, 0.815 with offline LLM enrichment and reranking. Details: v4/README.md, v4/docs/ARCHITECTURE.md, v4/RESULTS.md.

Upgrading from 3.x: the memory-os-ai command now starts v4. To keep v3, point your MCP config at memory-os-ai-v3.

Concept

Memory OS AI transforms your local documents (PDF, DOCX, images, audio) into a semantic memory queryable by any AI model through the MCP (Model Context Protocol).

Features

• 21 MCP tools for memory management, search, chat persistence, project linking, and cloud storage
• Semantic search with FAISS + SentenceTransformers (all-MiniLM-L6-v2)
• Multi-format ingestion: PDF, DOCX, TXT, images (OCR), audio (Whisper), PPTX
• Chat extraction: auto-detects Claude, ChatGPT, Copilot, and terminal history
• Cross-project linking: share memory across multiple workspaces
• Cloud storage overflow: auto-backup to Google Drive, iCloud, Dropbox, OneDrive, S3, Azure, Box, B2
• 3 transports: stdio (default), SSE (--sse), Streamable HTTP (--http)
• MCP Resources: memory://documents/*, memory://logs/conversation, memory://linked/*
• Local-first: all data on your machine by default, cloud only when disk runs low

21 MCP Tools

Quick Start

Prerequisites

• Python 3.10+
• Optional: tesseract (OCR), ffmpeg (audio), antiword (legacy .doc)

# macOS
brew install tesseract ffmpeg antiword

# Ubuntu/Debian
sudo apt-get install tesseract-ocr ffmpeg antiword

Install

git clone https://github.com/romainsantoli-web/Memory-os-ai.git
cd Memory-os-ai
pip install -e ".[dev,audio]"

Auto-Setup (recommended)

# Setup for your AI client:
memory-os-ai setup claude-code    # Claude Code
memory-os-ai setup codex          # Codex CLI
memory-os-ai setup vscode         # VS Code Copilot
memory-os-ai setup claude-desktop # Claude Desktop
memory-os-ai setup chatgpt        # ChatGPT (manual bridge)
memory-os-ai setup all            # All of the above

# Check status:
memory-os-ai setup status

Manual Start

# stdio (default — Claude Code, VS Code, Codex)
memory-os-ai

# SSE transport (port 8765)
memory-os-ai --sse

# Streamable HTTP (port 8765)
memory-os-ai --http

Cloud Storage (v3.1.0)

When local disk runs low (< 500 MB free by default), memory data automatically overflows to a configured cloud backend.

Supported Providers

Usage

# Configure via environment (auto-activates on server start)
export MEMORY_CLOUD_PROVIDER=icloud
export MEMORY_CLOUD_CONFIG='{"container": "memory-os-ai"}'
memory-os-ai

# Or configure at runtime via MCP tool:
#   memory_cloud_configure(provider="s3", credentials={"bucket": "my-bucket", ...})
#   memory_cloud_status()       → local disk + cloud usage
#   memory_cloud_sync("push")   → backup to cloud
#   memory_cloud_sync("pull")   → restore from cloud
#   memory_cloud_sync("auto")   → offload if disk low

Configuration

Environment Variables

Development

# Install dev dependencies
pip install -e ".[dev]"

# Run tests
python -m pytest tests/ -v

# Run with coverage
python -m pytest tests/ --cov=memory_os_ai --cov-report=term-missing

# Coverage threshold: 80% (enforced in pyproject.toml)

Part of the OpenClaw Ecosystem

Memory OS AI is designed to work alongside the OpenClaw agent infrastructure:

Together they form a complete stack: memory (this repo) → skills & souls (setup-vs-agent-firm) → security & orchestration (mcp-openclaw-extensions).
