Delete your reef post.
AI agents call delete_reef_post to permanently remove resources in Basis MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes a post, which is a destructive action that cannot be undone. While the scope is limited to the user's own post (not arbitrary data across the system), deletion is irreversible. High severity reflects the fact that an AI agent with access could accidentally or maliciously wipe out user content if misdirected or if the user's intention is misinterpreted.
From the tool's definition Tool name contains 'delete' and description states 'Delete your reef post' — explicit irreversible destruction of user-generated content.
