SelfHub MCP Server

Your Personal AI Memory Hub - Store and retrieve your personal data from any MCP-enabled AI assistant.

🎯 What is SelfHub?

SelfHub is a Model Context Protocol (MCP) server that acts as your personal digital memory. Store notes, preferences, code snippets, tasks, and any information you want - then access them seamlessly from any AI assistant that supports MCP (Claude Desktop, VS Code Copilot, etc.).

Think of it as your personal knowledge base that travels with you across all AI conversations.

🚀 Setup with Claude Desktop

Step 1: Install and Build

git clone https://github.com/Sagargupta16/SelfHub.git
cd SelfHub
pnpm install
cp .env.example .env   # set MONGODB_URI to your MongoDB connection string
pnpm build

# Optional: load sample data
pnpm seed

Step 2: Configure Claude Desktop

Open the Claude Desktop configuration file:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

Add this configuration (replace with your actual path):

{
  "mcpServers": {
    "selfhub": {
      "command": "node",
      "args": ["C:\\absolute\\path\\to\\SelfHub\\build\\index.js"]
    }
  }
}

Important for Windows: Use double backslashes (\\) in the path!

Step 3: Restart Claude Desktop

Completely quit and restart Claude Desktop.

Step 4: Test It!

In Claude, try:

• "List all my memories"
• "Search my memories for typescript"
• "Store that I prefer dark mode in all applications"

💻 Setup with VS Code

Step 1: Build the Server

pnpm build

Step 2: Configure VS Code

Create .vscode/mcp.json in your workspace (replace with your actual path):

{
  "servers": {
    "selfhub": {
      "type": "stdio",
      "command": "node",
      "args": ["C:\\absolute\\path\\to\\SelfHub\\build\\index.js"]
    }
  }
}

Then reload VS Code: Press Ctrl+Shift+P (or Cmd+Shift+P on Mac) → Type "Reload Window" → Press Enter

Step 3: Test in Copilot Chat

Open GitHub Copilot Chat (Ctrl+Alt+I) and try:

@workspace list my memories
@workspace search my memories for "typescript"
@workspace store in my memory: I love using pnpm for package management

Note: You need GitHub Copilot extension installed and enabled.

9. get_stats

Get usage statistics and insights.

Example:

• Most used tags

📚 Example Usage Scenarios

Personal Knowledge Management

Store that I prefer dark mode in all applications
Store my favorite TypeScript coding conventions
Remember that I use pnpm for package management
Search my memories for "preferences"

Project Development

Create a new context called "SelfHub Development" for project type
Store in SelfHub context: Database schema uses Drizzle ORM
Activate the SelfHub Development context
List all memories in the SelfHub context

Learning & Notes

Store as learning: Vector embeddings represent text as numerical arrays
Tag with "machine-learning" and "embeddings"
Search my learning memories for "embeddings"
List all my learning-related memories

Code Snippets

Store this code snippet: const sum = (a, b) => a + b
Category: code, Tags: javascript, utility
Search my code for "utility functions"

🗂️ Sample Data

Run pnpm seed to load 6 sample memories into your database:

1. mem_sample_001 - Dark mode UI preference (personal)
2. mem_sample_002 - TypeScript best practice (professional)
3. mem_sample_003 - MongoDB basics (learning)
4. mem_sample_004 - Documentation update task (tasks)
5. mem_sample_005 - NPM commands quick reference (code)
6. mem_sample_006 - SelfHub project overview (projects)

And 2 sample contexts:

1. ctx_sample_001 - SelfHub Development (project)
2. ctx_sample_002 - Personal Preferences (topic)

🔧 Development

Available Scripts

# Development mode (auto-reload with tsx)
pnpm dev

# Type checking
pnpm typecheck

# Build for production
pnpm build

# Clean build directory
rm -rf build

How It Works

1. MCP Server (src/index.ts) - Implements the MCP protocol, defines 9 tools
2. Services Layer - Business logic for memory and context operations
3. Storage Layer - MongoDB persistent storage via Mongoose (set MONGODB_URI in .env)
4. Models - TypeScript interfaces for type safety

Testing Locally

# Start the server
pnpm dev

# You should see:
# 🚀 SelfHub MCP Server running with MongoDB!
# 💾 Database: Connected and ready
# 🛠️  Available tools: 9 (store, retrieve, search, list, delete, contexts, stats)

The server runs on stdio (standard input/output) and waits for MCP protocol messages. You cannot interact with it directly - it needs an MCP client like Claude Desktop or VS Code.

🐛 Troubleshooting

Server Not Showing in Claude Desktop

1. Check the config path:

   • Make sure you're editing the correct config file
   • Use absolute path, not relative

2. Verify build exists:

   ls build/index.js

3. Check for typos:

   • Windows paths need double backslashes: C:\\path\\to\\
   • JSON syntax must be valid

4. Restart Claude completely:

   • Quit from system tray
   • Wait a few seconds
   • Start again

5. Check Claude logs:

   • Windows: %APPDATA%\Claude\logs
   • macOS: ~/Library/Logs/Claude

VS Code Not Showing Tools

1. Make sure GitHub Copilot is installed:

   • Press Ctrl+Shift+X
   • Search "GitHub Copilot"
   • Install both "GitHub Copilot" and "GitHub Copilot Chat"

2. Reload VS Code window:

   • Ctrl+Shift+P → "Reload Window"

3. Check the build:

   pnpm build

Build Errors

# Clean and rebuild
rm -rf build node_modules
pnpm install
pnpm build

Data Not Persisting

SelfHub uses MongoDB persistent storage - your data survives server restarts. If data isn't persisting:

1. Check your .env file:

   • Make sure MONGODB_URI points to your MongoDB instance
   • Copy from the template if missing: cp .env.example .env

2. Verify the connection:

   • The server logs ✅ Connected to MongoDB on startup
   • Without MONGODB_URI, it falls back to mongodb://localhost:27017/selfhub
