THE RISK

Critical Risk

Why delete_label needs a policy

Deleting a label is an irreversible action that removes metadata from a repository. While the blast radius is limited compared to deleting code or issues, it permanently removes the label and any associations, preventing undo. This qualifies as Destructive rather than Write (which is reversible) or Execute (which is contingent).

From the tool's definition Tool name is 'delete_label' and description states 'Delete a label from a repository'. The verb 'Delete' indicates irreversible removal of data.

POLICY

How to control delete_label

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

policy.json

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

delete_label 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 GitHub Repos Manager 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.
