+
+### File Watching for Development
+
+The `--watch` flag enables automatic server reloading when project files change, making development more efficient:
+
+```bash
+# Enable file watching with HTTP transport
+php artisan mcp:serve --transport=http --watch
 ```
 
+**What gets watched:**
+- MCP discovery directories (configured in `mcp.discovery.directories`)
+- MCP configuration files (`config/mcp.php`)
+- MCP route definitions (`routes/mcp.php`)
+
+**Features:**
+- Automatic server restart when PHP files in watched directories change
+- Preserves server configuration and transport options
+- Real-time feedback on file changes
+- Development-friendly error handling
+
+> ⚠️ **Note**: File watching is only supported with HTTP transport. STDIO transport cannot be reloaded automatically as it requires process restart. If you need to use the STDIO transport, consider using `npx mcp-remote`.
+
 **Command Options:**
 - `--transport`: Choose transport type (`stdio` or `http`)
 - `--host`: Host address for HTTP transport
-- `--port`: Port number for HTTP transport  
+- `--port`: Port number for HTTP transport
 - `--path-prefix`: URL path prefix for HTTP transport
+- `--watch`: Watch for file changes and automatically reload the server (HTTP transport only)
