Clear all bookmarks and groups. This is a destructive operation that requires explicit confirmation.
AI agents call clear_all_bookmarks to permanently remove resources in MCP Bookmarks — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes all bookmarks and groups, which cannot be undone. It affects all stored code annotations and organizational metadata within the codebase. While not directly affecting code or financial systems, the loss of all bookmark data represents a significant destructive operation with high blast radius if invoked by an AI agent without proper safeguards.

clear_all_bookmarks 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 clear_all_bookmarks 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 clear_all_bookmarks. 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.
