This tool retrieves/downloads existing release assets without modifying, deleting, or executing anything. It is a pure read operation analogous to fetching or getting published data. No destructive, financial, or code execution capability is involved. The low severity reflects minimal blast radius—downloading public or authorized artifacts poses no risk of unintended data loss, financial impact, or system compromise.

From the tool's definition Tool name contains 'download' and description states 'Download a release asset' — a retrieval operation with no side effects. Release assets are immutable, published artifacts.

POLICY

How to control gitlab_download_release_asset

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_download_release_asset:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gitlab_download_release_asset": {}
  }
}

gitlab_download_release_asset is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
