Delete keys from the workspace color palette and return the resulting palette.
AI agents call palette_delete to permanently remove resources in Whiteboard — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool explicitly deletes keys from the color palette. Deletion is irreversible, matching the Destructive category. Severity is medium since it only affects color palette configuration, not core canvas content, but the action cannot be undone.

Attacks that exploit this kind of access
Delete keys from the workspace color palette and return the resulting palette. It is categorised as a Destructive tool in the Whiteboard MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Whiteboard MCP server in PolicyLayer and add a rule for palette_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 Whiteboard. Nothing to install.
palette_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 palette_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 palette_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.
palette_delete is provided by the Whiteboard MCP server (kamiazya/whiteboard). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
