 ## Configuration Management
 
-### Automatic Updates
+### Automatic Token Refresh
+
+The MCP Gateway includes an [Automated Token Refresh Service](token-refresh-service.md) that provides continuous token management:
+
+```bash
+# Start the token refresh service (runs in background)
+./start_token_refresher.sh
+
+# Service automatically:
+# - Monitors token expiration (1-hour buffer by default)
+# - Refreshes tokens before they expire
+# - Updates all MCP client configurations
+# - Generates fresh configs for all AI assistants
+```
+
+**Key Benefits:**
+- **Zero Downtime**: Tokens refresh automatically before expiration
+- **Continuous Operation**: AI assistants never lose access due to expired tokens
+- **Multiple Client Support**: Updates configurations for VS Code, Roo Code, Claude Code, etc.
+- **Background Operation**: Runs as a service with comprehensive logging
