WHAT LINE_DELETE_AUDIENCE ON LINE OA MCP ULTIMATE DOES

AI agents call line_delete_audience to permanently remove resources in Line Oa Mcp Ultimate — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

THE RISK

Critical Risk

This tool permanently deletes data (an audience group) with no ability to recover it. Deletion is irreversible, placing it squarely in the Destructive category. While the confirm=true safeguard mitigates some risk, an AI agent with access could still cause significant business impact by removing marketing segments or customer groups.

From the tool's definition Tool name 'line_delete_audience' and description states 'Delete an audience group. Irreversible — requires confirm=true.' The description explicitly confirms the action cannot be undone and requires explicit confirmation.

HOW TO CONTROL LINE_DELETE_AUDIENCE

PolicyLayer is an MCP gateway — it sits between your AI agents and Line Oa Mcp Ultimate, and nothing reaches the server without passing your rules. This is the rule we recommend for line_delete_audience:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "line_delete_audience"
  ]
}

line_delete_audience disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
