🧠 Personal Memory Gateway (PMG)

The Privacy-First Memory Layer for AI.
Seamlessly bridge your local knowledge with any AI assistant through a secure, MCP-compatible gateway.

🚀 Quick Start

Get up and running in seconds with zero configuration:

npx @shubham-01-star/pmg init

✨ Overview

Personal Memory Gateway (PMG) is a local-first backend designed to store, manage, and serve your personal knowledge to AI models. It acts as a secure "VPN for your memory," ensuring that sensitive data is redacted and privacy is gated before any context is shared.

🛠️ Core Capabilities

• MCP Tool Integration: Seamlessly connects to Cursor, Claude Desktop, and other MCP clients via query_personal_memory and save_memory tools.
• Privacy-First Ingestion: Automatically watches local directories, chunks documents, and stores them in a local vector database (LanceDB).
• Intelligent Redaction: Applies a multi-stage pipeline to redact PII and sensitive information before retrieval.
• Archestra Integration: Optionally route responses through high-performance gateways like Archestra (supporting Gemini/OpenAI).
• Telemetry Dashboard: Monitor system health and manage your indexed data through a built-in web interface.

🔌 MCP Client Configuration

Add PMG to your mcpServers configuration:

{
  "mcpServers": {
    "pmg": {
      "command": "npx",
      "args": ["-y", "@shubham-01-star/pmg"],
      "env": {
        "INGEST_DIR": "/path/to/your/data",
        "LANCE_DB_PATH": "/path/to/lancedb/storage"
      }
    }
  }
}

⚙️ Environment Variables

| Variable | Description | Default | | :------------------- | :----------------------------------------------- | :-------- | | INGEST_DIR | Directory to watch for memory files | my_data | | ARCHESTRA_ENABLE | Enable Archestra integration (0 or 1) | 0 | | EMBEDDING_PROVIDER | Embedding model source (local, gemini, etc.) | local | | DASHBOARD_PORT | Port for the telemetry dashboard | 8787 | | PRIVACY_REDACT_PII | Enable PII redaction pipeline | 1 |

📊 Dashboard

Once running, access the telemetry dashboard at: 👉 http://localhost:8787/dashboard

• Monitor: Real-time events and memory retrieval stats.
• Manage: Upload new documents or clear existing memories.
• Status: Visual health probes for all internal services.

🧪 Testing & Verification

PMG includes a comprehensive suite of smoke tests and backend validations.
