WHAT IT DOES

What delete_tag does on Gitlab Mcp

AI agents call delete_tag to permanently remove resources in Gitlab Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_tag is rated Critical

Deleting a repository tag cannot be undone and removes important version markers that may be referenced by releases, deployments, or external systems. While not as critical as deleting entire repositories or code, it is destructive in nature and warrants a 'Destructive' classification with high severity due to the potential to disrupt CI/CD pipelines, release processes, and developer workflows that depend on those…

From the tool's definition Tool name is 'delete_tag' and description states 'Delete a repository tag' — this is an irreversible deletion operation on version control metadata.

RECOMMENDED RULE

The rule that runs delete_tag safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For delete_tag, this is the rule to start with:

delete_tag Hidden

delete_tag is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.

  "version": "1",
  "default": "deny",
  "hide": [
    "delete_tag"
  ]
}

RESTRICT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every delete_tag call is checked against it from then on.
