Removes a slide by its 1-based index from the frontmost presentation.
AI agents call delete_slide to permanently remove resources in Keynote MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This action destroys data (slide content) that cannot be automatically restored by the tool itself. While users can manually undo in Keynote, the tool performs a destructive operation that permanently modifies the presentation structure. The severity is high rather than critical because it affects one presentation's content rather than system-wide or financial impacts.
From the tool's definition The tool 'delete_slide' irreversibly removes a slide from a presentation. The description states it 'Removes a slide by its 1-based index' with no undo capability mentioned, making this an unrecoverable deletion of content.
Attacks that exploit this kind of access
Removes a slide by its 1-based index from the frontmost presentation. It is categorised as a Destructive tool in the Keynote MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Keynote MCP Server MCP server in PolicyLayer and add a rule for delete_slide: 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 Keynote MCP Server. Nothing to install.
delete_slide 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_slide 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_slide. 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_slide is provided by the Keynote MCP Server MCP server (superdwayne/keynotemp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
