Please join the conversation if you have concerns around the current auth specification. - Servers **MUST**: - Validate all tool inputs - Implement proper access controls - Rate limit tool invocations - Sanitize tool outputs - Clients **SHOULD**: - Prompt for user confirmation on sensitive operations - Show tool inputs to the user before calling the server, to avoid malicious or accidental data exfiltration - Validate tool results before passing to LLM - Implement timeouts for tool calls - Log tool usage for audit purposes > [!WARNING] > For trust & safety and security, clients **MUST** consider tool annotations to be untrusted unless they come from trusted servers. > [!WARNING] > For trust & safety and security, there **SHOULD** always be a human in the loop* with the ability to deny tool invocations. > > Applications **SHOULD**: > > - Provide UI that makes clear which tools are being exposed to the AI model. > - Insert clear visual indicators when tools are invoked. > - Present confirmation prompts to the user for operations, to ensure a human is in the loop. > [!NOTE] > *Human-in-the-Loop (HITL) means that user help monitor and guide automated tasks, like deciding whether to accept tool requests in Cursor. ## 📃 Papers -
