Interface ToolRegistrar

Minimal registration interface implemented by ToolRegistrationAdapter.

Remarks

Tool modules depend on this interface so tests can register against a local adapter and createServer can filter or wrap callbacks consistently.

interface ToolRegistrar {
    hasTool(name: string): boolean;
    registerTool<TArgs = any>(
        name: string,
        config: ToolRegistrationConfig,
        cb: ToolCallback<TArgs>,
    ): void;
}
