Why gitlab_delete_tag needs a policy

This tool permanently and irreversibly deletes a repository tag, which constitutes destruction of data. The description explicitly states 'Irreversible', confirming the operation cannot be undone. While the blast radius is limited to a single tag rather than an entire repository, the irreversible nature of deletion places this in the Destructive category rather than Write.

From the tool's definition Delete a repository tag permanently. Irreversible for tag_name.

POLICY

How to control gitlab_delete_tag

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

policy.json

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

gitlab_delete_tag 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 Gitlab — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
