DESTRUCTIVE AND IRREVERSIBLE: Permanently deletes ALL bookmarks one by one. This cannot be undone. Always confirm explicitly with the user before calling this tool.
AI agents call delete_all_bookmarks to permanently remove resources in X (Twitter) MCP server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool removes data that cannot be recovered. Although the blast radius is limited to a user's bookmarks (not system-wide data), the irreversible nature and the scale ('ALL bookmarks') make it a destructive operation. The explicit warning in the description confirms the risk severity is high rather than medium.
From the tool's definition Tool description explicitly states 'DESTRUCTIVE AND IRREVERSIBLE: Permanently deletes ALL bookmarks one by one. This cannot be undone.' The verb 'deletes' combined with 'IRREVERSIBLE' and 'cannot be undone' are unambiguous markers of destructive operations.
Documented attack patterns abuse exactly the kind of access delete_all_bookmarks gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and X (Twitter) MCP server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_all_bookmarks:
{
"version": "1",
"default": "deny",
"hide": [
"delete_all_bookmarks"
]
}delete_all_bookmarks disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
