Struct AuditLayer 

pub struct AuditLayer { /* private fields */ }

Tower layer that adds structured audit logging to all MCP requests.

This layer emits one structured tracing event per request at completion, using target mcp::audit. Events contain the method, operation details, duration, status, and tool annotation hints when available.

use tower_mcp::middleware::AuditLayer;

let transport = HttpTransport::new(router)
    .layer(AuditLayer::new());
