```


## 📋 Prerequisites

- Python 3.10 or higher
- Azure CLI installed and authenticated (`az login`)
- Access to Azure Data Explorer cluster(s)

## 🚀 One-Command Installation

### Quick Install (Recommended)

#### From Source

```bash
git clone https://github.com/4R9UN/mcp-kql-server.git && cd mcp-kql-server && pip install -e .
```
### Alternative Installation Methods

```bash
pip install mcp-kql-server
```

**That's it!** The server automatically:
- ✅ Sets up memory directories in `%APPDATA%\KQL_MCP` (Windows) or `~/.local/share/KQL_MCP` (Linux/Mac)
- ✅ Configures optimal defaults for production use
- ✅ Suppresses verbose Azure SDK logs
- ✅ No environment variables required


## 📱 MCP Client Configuration

### Claude Desktop

Add to your Claude Desktop MCP settings file (`mcp_settings.json`):

**Location:**
- **Windows**: `%APPDATA%\Claude\mcp_settings.json`
- **macOS**: `~/Library/Application Support/Claude/mcp_settings.json`
- **Linux**: `~/.config/Claude/mcp_settings.json`

```json
{
  "mcpServers": {
    "mcp-kql-server": {
      "command": "python",
      "args": ["-m", "mcp_kql_server"],
      "env": {}
    }
  }
}
```

### VSCode (with MCP Extension)

Add to your VSCode MCP configuration:

**Settings.json location:**
- **Windows**: `%APPDATA%\Code\User\settings.json`
- **macOS**: `~/Library/Application Support/Code/User/settings.json`
- **Linux**: `~/.config/Code/User/settings.json`

```json
{
  "mcp.servers": {
    "mcp-kql-server": {
      "command": "python",
      "args": ["-m", "mcp_kql_server"],
      "cwd": null,
      "env": {}
    }
  }
}
```

### Roo-code (Cline Extension)

Add to your Roo-code MCP settings:

**MCP Settings location:**
- **All platforms**: Through Roo-code extension settings or `mcp_settings.json`

```json
{
  "mcpServers": {
    "kql-server": {
      "command": "python",
      "args": ["-m", "mcp_kql_server"],
      "env": {},
      "description": "KQL Server for Azure Data Explorer queries with AI assistance"
    }
  }
}
```

### Generic MCP Client

For any MCP-compatible application:

```bash
# Command to run the server
python -m mcp_kql_server

# Server provides these tools:
# - kql_execute: Execute KQL queries with AI context
# - kql_schema_memory: Discover and cache cluster schemas
```

### Configuration with Environment Variables

You can customize the server behavior with environment variables:

```json
{
  "mcpServers": {
    "mcp-kql-server": {
      "command": "python",
      "args": ["-m", "mcp_kql_server"],
      "env": {
        
      }
    }
  }
}
```
## 🔧 Quick Start

### 1. Authenticate with Azure (One-time setup)

```bash
az login
```

### 2. Start the MCP Server (Zero configuration)

```bash
python -m mcp_kql_server
```

The server starts immediately with:
- 📁 **Auto-created memory path**: `%APPDATA%\KQL_MCP\cluster_memory`
- 🔧 **Optimized defaults**: No configuration files needed
- 🔐 **Secure setup**: Uses your existing Azure CLI credentials

### 3. Use via MCP Client

The server provides two main tools:

> #### `kql_execute` - Execute KQL Queries with AI Context
> #### `kql_schema_memory` - Discover and Cache Cluster Schemas


## 💡 Usage Examples

### Basic Query Execution

Ask your MCP client (like Claude):
> "Execute this KQL query against the help cluster: `cluster('help.kusto.windows.net').database('Samples').StormEvents | take 10` and summarize the result and give me high level insights "

### Complex Analytics Query

Ask your MCP client:
> "Query the Samples database in the help cluster to show me the top 10 states by storm event count, include visualization"

### Schema Discovery

Ask your MCP client:
> "Discover and cache the schema for the help.kusto.windows.net cluster, then tell me what databases and tables are available"

### Data Exploration with Context

Ask your MCP client:
> "Using the StormEvents table in the Samples database on help cluster, show me all tornado events from 2007 with damage estimates over $1M"

### Time-based Analysis

Ask your MCP client:
> "Analyze storm events by month for the year 2007 in the StormEvents table, group by event type and show as a visualization"

## 🚀 Advanced Usage

### Custom Memory Path

```python
{
    "tool": "kql_execute",
    "input": {
        "query": "...",
        "cluster_memory_path": "/custom/memory/path"
    }
}
```

### Force Schema Refresh

```python
{
    "tool": "kql_schema_memory",
    "input": {
        "cluster_uri": "mycluster",
        "force_refresh": true
    }
}
```

### Performance Optimization

```python
{
    "tool": "kql_execute",
    "input": {
        "query": "...",
        "use_schema_context": false,  # Disable for faster execution
        "visualize": false           # Disable for minimal response
    }
}
```

## 🔒 Security

- **Azure CLI Authentication**: Leverages your existing Azure device login
- **No Credential Storage**: Server doesn't store authentication tokens
- **Local Memory**: Schema cache stored locally, not transmitted

## 🐛 Troubleshooting

### Common Issues

1. **Authentication Errors**
   ```bash
   # Re-authenticate with Azure CLI
   az login --tenant your-tenant-id
   ```

2. **Memory Issues**
   ```bash
   # Clear schema cache if corrupted (automatic backup created)
   # Windows:
   del "%APPDATA%\KQL_MCP\schema_memory.json"
   
   # macOS/Linux:
   rm ~/.local/share/KQL_MCP/schema_memory.json
   ```

3. **Connection Timeouts**
   - Check cluster URI format
   - Verify network connectivity
   - Confirm Azure permissions

4. **Memory Path Issues**
   - Server automatically creates fallback directory in `~/.kql_mcp_memory` if default path fails
   - Check logs for memory path initialization messages
