Struct VisibilitySessionGuard 

pub struct VisibilitySessionGuard { /* private fields */ }

Progressive disclosure through component visibility control. RAII guard that automatically cleans up session visibility state when dropped.

This is the recommended way to manage session visibility lifetime. Create a guard at the start of a session and let it clean up automatically when the session ends.

Example

use turbomcp_server::visibility::VisibilityLayer;

async fn handle_connection<H: McpHandler>(layer: &VisibilityLayer<H>, session_id: &str) {
    let _guard = layer.session_guard(session_id);

    // Enable admin tools for this session
    layer.enable_for_session(session_id, &["admin".to_string()]);

    // ... handle requests ...

} // State automatically cleaned up here
