+## Selective Restart Capability
+
+The Gateway supports **selective restart** functionality, allowing individual MCP servers to be managed without requiring a full gateway restart. This feature dramatically improves configuration update performance and eliminates downtime for unchanged servers.
+
+### Key Features
+
+- **Individual Server Control**: Add, remove, or restart specific MCP servers via HTTP API
+- **Change Detection**: Automatically detects added, removed, and modified server configurations
+- **Fallback Safety**: Falls back to full restart if selective operations fail
+- **Zero Downtime**: Unchanged servers continue running during configuration updates
+
+### API Endpoints
+
+The Gateway exposes HTTP endpoints for selective server management:
+
+- `POST /api/mcp/servers` - Add new MCP servers to running gateway
+- `DELETE /api/mcp/servers/:serverName` - Remove specific servers
+- `POST /api/mcp/servers/:serverName/restart` - Restart individual servers
+
+### Implementation Services
+
+- **Selective Restart Service**: Handles HTTP communication with running gateway processes
+- **Configuration Change Service**: Detects configuration differences and orchestrates selective operations
+- **Process Manager Integration**: Provides individual server lifecycle control capabilities

+## Transport-Specific Session Handling
+
+### SSE Transport Sessions
+SSE transport requires persistent sessions for connection management:
+
+- **Mandatory Sessions**: All SSE connections must have associated sessions
+- **Stream Binding**: Sessions are bound to specific SSE streams
+- **Real-time Communication**: Messages sent via SSE events in real-time
+- **Connection Lifecycle**: Session lifecycle tied to SSE connection state

+### Streamable HTTP Transport Sessions
+Streamable HTTP transport supports optional sessions for enhanced functionality:

+- **Optional Sessions**: Sessions can be used but are not required
+- **Stateless Operation**: Supports both stateless and session-based operation
+- **Header-Based**: Session IDs passed via `Mcp-Session-Id` header
