THE RISK

Critical Risk

Why meta_delete_comment needs a policy

This tool permanently deletes user-generated content (comments) from Facebook Pages with no undo capability. Deletion is irreversible and fits the Destructive category definition. Severity is high because an AI agent with misuse could delete large volumes of comments, damage community discourse, suppress user feedback, or cause reputational harm to page administrators.

From the tool's definition Tool name is 'meta_delete_comment' and description states 'Deletes a comment on a Facebook Page post. Permanent action.' The word 'Deletes' and 'Permanent action' explicitly indicate irreversible removal of data.

POLICY

How to control meta_delete_comment

PolicyLayer is an MCP gateway — it sits between your AI agents and Meta MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meta_delete_comment:

policy.json

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

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

Create a free account and register Meta MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
