### Schema Memory Discovery Flow

The schema memory flow is integrated into query execution, but it now reuses existing cached schema before attempting live discovery. If a table schema is already available in CAG/schema memory, the server will use that cached schema instead of re-indexing it.

```


## 📋 Prerequisites

- Python 3.10 or higher
- [Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli-windows?view=azure-cli-latest&pivots=msi) 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

> **One-time install (any platform):**
> ```bash
> pip install --upgrade mcp-kql-server
> ```
> After install, configure your MCP client to launch the server via the Python module entry point: `python -m mcp_kql_server`. This works on every platform where Python is on `PATH` and does not depend on the location of the `mcp-kql-server` console script. (The console script is still installed by `pip` and remains supported for backward compatibility — see the alternative snippets below.)

### 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": {
    "mcpKqlServer": {
      "type": "stdio",
      "command": "python",
      "args": ["-m", "mcp_kql_server"]
    }
  }
}
```

<details>
<summary>Alternatives: platform-stable launchers or the installed console script</summary>

Windows (the `py` launcher is commonly available as `py`; use `Get-Command py` if you need its full path):
```json
{
  "mcpServers": {
    "mcpKqlServer": {
      "type": "stdio",
      "command": "py",
      "args": ["-3", "-m", "mcp_kql_server"]
    }
  }
}
```
On macOS / Linux replace `"py"` with `"python3"` and drop the `"-3"` arg.

</details>

### VSCode (with MCP Extension)

Add to your VSCode MCP configuration:

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

```json
{
  "servers": {
    "mcpKqlServer": {
      "type": "stdio",
      "command": "py",
      "args": ["-3", "-m", "mcp_kql_server", "--transport", "stdio"],
      "timeout": 300000,
      "env": {
        "FASTMCP_TRANSPORT": "stdio",
        "MCP_KQL_AUTH_ON_STARTUP": "false",
        "MCP_KQL_CHECK_FOR_UPDATES": "false",
        "MCP_KQL_DEFER_AUTH": "1",
        "MCP_KQL_SKIP_STARTUP_VERSION_CHECK": "1",
        "MCP_KQL_AUTH_CHECK_TIMEOUT_SECONDS": "10",
        "MCP_KQL_AUTH_LOGIN_TIMEOUT_SECONDS": "120",
        "MCP_KQL_SQLITE_BUSY_TIMEOUT_MS": "30000"
      }
    }
  }
}
```

> **If VS Code logs `spawn ...PythonNNN/python.exe ENOENT`**, the Python extension is substituting a cached interpreter path for `"python"`. Switch to `"py"` (Windows) / `"python3"` (macOS/Linux), or to the `"mcp-kql-server"` console script that `pip install` drops on `PATH`. See [docs/troubleshooting.md](docs/troubleshooting.md#8-mcp-integration-issues) for full details.

> **Windows tip**: use `py -3 -m mcp_kql_server` so VS Code does not need a user-specific Python path. If you must use a full path locally, keep it in your private `mcp.json`, not in shared documentation.

> **If the server starts but VS Code still shows no tools**, run `MCP: Reset Cached Tools`, then `MCP: Reset Trust`, and restart the server from `MCP: List Servers`. VS Code stores trust and cached tools separately from `mcp.json`, so a previous failed launch can keep the old empty state until you reset it.

### Shared HTTP Mode for Multiple MCP Clients

Use shared HTTP when VS Code, GitHub Copilot CLI, agents, or other MCP clients should connect to one persistent MCP KQL server process.

Start the server:

```bash
python -m mcp_kql_server --transport http --host 127.0.0.1 --port 8000 --http-path /mcp --stateless-http
```

Client configuration:

```json
{
  "servers": {
    "mcpKqlServer": {
      "type": "http",
      "url": "http://127.0.0.1:8000/mcp"
    }
  }
}
```

### Runtime Settings Added in v2.1.3

| Option or environment variable | Purpose | Default |
| --- | --- | --- |
| `--transport`, `FASTMCP_TRANSPORT` | `stdio`, `http`, `streamable-http`, or `sse` | `stdio` |
| `--host`, `FASTMCP_HOST` | HTTP bind host | `127.0.0.1` |
| `--port`, `FASTMCP_PORT` | HTTP bind port | `8000` |
| `--http-path`, `FASTMCP_STREAMABLE_HTTP_PATH` | Streamable HTTP endpoint path | `/mcp` |
| `--stateless-http`, `FASTMCP_STATELESS_HTTP` | Stateless HTTP mode for shared deployments | `false` |
| `--auth-on-startup`, `MCP_KQL_AUTH_ON_STARTUP` | Check Azure CLI auth before startup | `false` |
| `--check-updates`, `MCP_KQL_CHECK_FOR_UPDATES` | Check PyPI for package updates before startup | `false` |
| `MCP_KQL_AUTH_CHECK_TIMEOUT_SECONDS` | Azure CLI auth check timeout | `10` |
| `MCP_KQL_AUTH_LOGIN_TIMEOUT_SECONDS` | Interactive Azure login timeout | `120` |
| `MCP_KQL_SQLITE_BUSY_TIMEOUT_MS` | SQLite busy timeout for concurrent local MCP instances | `30000` |

### Roo-code Or Cline (VS-code Extentions)

Ask or Add to your Roo-code Or Cline MCP settings:

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

```json
{
  "mcp-kql-server": {
    "type": "stdio",
    "command": "python",
    "args": ["-m", "mcp_kql_server"],
    "alwaysAllow": []
  }
}
```

### Generic MCP Client

For any MCP-compatible application:

```bash
# Preferred: invoke as a Python module (cross-platform)
python -m mcp_kql_server

# Platform-stable launchers (recommended if `python` is ambiguous on PATH)
py -3 -m mcp_kql_server     # Windows
python3 -m mcp_kql_server   # macOS / Linux

# Equivalent console script installed by pip
mcp-kql-server

# Shared HTTP mode for multiple clients
python -m mcp_kql_server --transport http --host 127.0.0.1 --port 8000 --http-path /mcp --stateless-http

# Server provides these tools:
# - execute_kql_query: Execute KQL or generate KQL from natural language
# - kql_schema_memory: Discover, cache, and inspect cluster schemas
```
## 🔧 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
```

To inspect the installed server version and runtime defaults:

```bash
python -m mcp_kql_server --info --json
```

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
- ⚡ **Fast startup**: Auth and update checks are deferred unless explicitly enabled

### 3. Use via MCP Client

The server provides two main tools:

> #### `execute_kql_query` - Execute KQL queries or generate KQL from natural language
> #### `kql_schema_memory` - Discover, refresh, and inspect cached 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"

## 🔒 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
   # The memory cache is now managed automatically. If you suspect issues,
   # you can clear the cache directory, and it will be rebuilt on the next query.
   # Windows:
   rmdir /s /q "%APPDATA%\KQL_MCP\unified_memory.json"
   
   # macOS/Linux:
   rm -rf ~/.local/share/KQL_MCP/cluster_memory
   ```

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