Delete a highlight permanently. This action cannot be undone.
AI agents call highlight_delete to permanently remove resources in Raindrop Io MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently deletes highlights without any recovery option. Even though highlights are typically lower-value data compared to full bookmarks, the permanent and irreversible nature of the deletion classifies this as Destructive rather than Write. An AI agent with this capability could irreversibly destroy user content, justifying high severity.
From the tool's definition Tool description explicitly states: 'Delete a highlight permanently. This action cannot be undone.' The words 'Delete' and 'permanently' combined with 'cannot be undone' clearly indicate irreversible data destruction.

Register the Raindrop Io MCP Server MCP server in PolicyLayer and add a rule for highlight_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 Raindrop Io MCP Server. Nothing to install.
highlight_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 highlight_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.
