MCP Local Memory Service is a high-performance Model Context Protocol (MCP) server that provides long-term, high-signal memory for AI Agents (such as Claude Desktop, Cursor, or Windsurf).

Built with a Local-First philosophy, this service stores architectural decisions, code patterns, and critical facts locally on your machine using SQLite and AI-powered Semantic Search.

🚀 Key Features

• 🧠 Semantic Search (V2): Find memories based on meaning, not just keywords, using the all-MiniLM-L6-v2 model locally.
• 🔄 Tech-Stack Affinity: Share knowledge across repositories intelligently based on technology tags (e.g., Filament memories in Repo A are accessible in Repo B).
• 🛡️ Anti-Hallucination Guard: Prevents Agents from hallucinating with strict similarity thresholds and decision conflict detection.
• 📉 Automatic Memory Decay: Automatically archives obsolete memories to keep the context clean and relevant.
• 📊 Glassy Dashboard: Visualize memories, usage statistics, and audit interaction logs through a modern web interface.

🔌 MCP Usage & Configuration

Add this service to your AI Agent (Claude Desktop, Cursor, Windsurf, etc.) using one of the methods below.

💡 Recommendation: If your MCP runs frequently (agents, CI, automation), avoid npx and use a global or local install instead. It reduces unnecessary NPM downloads and speeds up Agent startup.

🚀 Quick Start (Zero Setup)

Best for first-time users or quick testing. This uses npx to run the server without any permanent setup.

"local-memory": {
  "command": "npx",
  "args": ["-y", "@vheins/local-memory-mcp"],
  "type": "stdio"
}

• Uses npx: Automatically handles the execution.
• Tradeoff: May re-download the package in some environments and is not optimal for frequent execution.

⚡ Recommended for Production / Frequent Usage

This method ensures the fastest startup times and maximum reliability for daily use.

1. Install globally:

   npm install -g @vheins/local-memory-mcp

2. Add to your configuration:

   "local-memory": {
     "command": "local-memory-mcp",
     "type": "stdio"
   }

• Faster startup: No network checks required on every start.
• No repeated downloads: Saves bandwidth and avoids NPM registry dependency.
• Better for automation: More stable for heavy-duty Agent workflows.

🧠 How It Works (Important Insight)

• npx usage: When you use npx, it often performs a network request to check for the latest version or re-downloads the package if it's not in the cache. Since MCP clients start and stop tools frequently, this can lead to hundreds of unnecessary downloads.
• Installed binary: By installing the package, you keep a permanent copy on your disk. The Agent reuses this local version instantly, providing a much smoother experience.

How to Run

local-memory-mcp dashboard

If not installed globally, use: npx @vheins/local-memory-mcp dashboard

Developer Workflow (Dashboard UI)

The dashboard UI is built with Svelte 5 + Vite. Source files live in src/dashboard/ui/.

# Start the API server (port 3456)
npm run dashboard

# In a separate terminal, start the Svelte dev server (port 5173)
npm run dashboard:dev
# → Open http://localhost:5173 (proxies /api to :3456)

# Build Svelte UI for production (output → dist/dashboard/public/)
npm run dashboard:build

# Full production build (Svelte + TypeScript)
npm run build

The server serves the compiled Svelte build from dist/dashboard/public/ in production.

Auto-launch in VS Code

Add this to your .vscode/tasks.json to have the dashboard start automatically:

{
  "version": "2.0.0",
  "tasks": [
    {
      "label": "Launch Memory Dashboard",
      "type": "shell",
      "command": "npx -y @vheins/local-memory-mcp dashboard",
      "isBackground": true,
      "runOptions": { "runOn": "folderOpen" }
    }
  ]
}
