Delete a note by its ID
AI agents call delete_note to permanently remove resources in MCP HTTP Server Demo — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes notes without possibility of recovery. Even though the blast radius is limited to user notes (not system-critical data), deletion is an irreversible operation that destroys data. Destructive is the appropriate category as it ranks above Write and Execute.
From the tool's definition Tool name is 'delete_note' and description states 'Delete a note by its ID'. The verb 'delete' indicates irreversible removal of data.
Attacks that exploit this kind of access
Delete a note by its ID. It is categorised as a Destructive tool in the MCP HTTP Server Demo MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MCP HTTP Server Demo MCP server in PolicyLayer and add a rule for delete_note: 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 HTTP Server Demo. Nothing to install.
delete_note 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 delete_note 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 delete_note. 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.
delete_note is provided by the MCP HTTP Server Demo MCP server (mlvalidationdebug/mcp-server-http-demo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
