RISK

Why gitlab_mr_create is rated Medium

Creating a merge request is a write operation that modifies repository metadata and state. It is reversible (MRs can be closed/deleted), so it does not qualify as Destructive. It does not execute arbitrary code or delete data.

From the tool's definition Tool name 'gitlab_mr_create' and description 'Open a GitLab merge request' indicate the tool creates a merge request, which is a reversible write operation that modifies repository state by proposing code changes.

RECOMMENDED RULE

The rule that runs gitlab_mr_create safely

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

gitlab_mr_create Rate-limited

gitlab_mr_create stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gitlab_mr_create": {
      "limits": [
        {
          "counter": "gitlab_mr_create_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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