THE RISK

Critical Risk

Why neowiki-delete-subject needs a policy

The tool irreversibly removes data (a NeoWiki Subject) from a wiki page. While it requires edit permissions, the deletion operation cannot be undone without restore/recovery mechanisms external to this tool. This qualifies as Destructive rather than Write.

From the tool's definition Tool name contains 'delete' and description explicitly states 'Deletes one NeoWiki Subject by ID from its page'. This is an irreversible deletion operation.

POLICY

How to control neowiki-delete-subject

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "neowiki-delete-subject"
  ]
}

neowiki-delete-subject 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.
