Delete a note by id.
AI agents call note_delete to permanently remove resources in MCP Object-Authz Lab — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes data without the ability to undo the operation. In a multi-tenant vulnerable-by-design lab environment (BOLA/IDOR focus), this becomes critical because authorization bypass could allow attackers to delete other users' notes.
From the tool's definition Tool name 'note_delete' and description 'Delete a note by id' directly indicate irreversible deletion of data.
Attacks that exploit this kind of access
Delete a note by id. It is categorised as a Destructive tool in the MCP Object-Authz Lab MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP Object-Authz Lab MCP server in PolicyLayer and add a rule for note_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Object-Authz Lab. Nothing to install.
note_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the note_delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for note_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
note_delete is provided by the MCP Object-Authz Lab MCP server (wrg-11/mcp-objauthz-lab). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
