Kusto MCP Server for VS Code + GitHub Copilot

Connect your Kusto database to GitHub Copilot in VS Code for intelligent data querying!

🚀 Quick Setup

1. Install Dependencies

# Activate virtual environment
venv\Scripts\activate

# Install all required packages from requirements.txt
pip install -r requirements.txt

2. Configure Your Cluster

Edit config/config.json with your Kusto cluster details:

{
  "clusters": {
    "production": {
      "url": "${KUSTO_CLUSTER_URL}",
      "database": "${KUSTO_DATABASE}"
    }
  },
  "logging": {
    "level": "INFO",
    "file": "logs/mcp-kusto-server.log"
  },
  "settings": {
    "default_limit": 1000,
    "timeout_seconds": 30
  }
}

put in the kusto information in .env file

3. Pre-Authenticate

python pre_auth.py

• Choose Option 2 (Interactive Browser)
• Your browser will open for Microsoft authentication
• Sign in with your account
• This caches your credentials for VS Code

4. Configure VS Code MCP Settings

1. Open Command Palette (Ctrl+Shift+P)
2. Type: "MCP: Open MCP Settings"
3. Navigate to .vscode/mcp.json
4. Add your server configuration:

{
    "servers": {
        "kusto": {
            "command": "your-location/mcp-kusto-server/venv/Scripts/python.exe",
            "args": ["your-location/mcp-kusto-server/mcp_server_cached_auth.py"],
            "env": {
                "KUSTO_CONFIG_FILE": "your-location/mcp-kusto-server/config/config.json"
            }
        }
    }
}

⚠️ Update the paths to match your actual file locations!

5. Start the MCP Server in VS Code

1. Go to .vscode/mcp.json (or wherever your MCP settings are)
2. Find your "kusto" server in the list
3. Click "Start" to start the server
4. Verify it shows as "Running"

6. Enable Copilot Agent Mode

1. Open GitHub Copilot Chat (sidebar or Ctrl+Shift+I)
2. Enable Agent Mode (toggle switch in chat interface)
3. Verify Copilot can see your MCP tools

🎯 Usage Examples

Once everything is running, ask Copilot:

"List all tables in my Kusto database"

"Show me the schema of the Users table" 

"Query the Events table for errors in the last hour"

"Find the top 10 most active users in the UserActivity table"

"Analyze trends in the LogEntries table over the past week"

🔧 Available Tools

Your Copilot now has access to:

• execute_kql - Run any KQL query
• list_tables - Show available tables
• get_table_schema - Get table structure
