THE RISK

Medium Risk

Why gitlab_create_group_wiki_page needs a policy

This tool creates (writes) a new wiki page within a GitLab group. Wiki pages are modifiable and deletable, making this a reversible write operation rather than destructive. The blast radius is medium because malicious wiki creation could spread misinformation or clutter the repository documentation, but the harm is containable through page deletion or rollback.

From the tool's definition Tool name 'gitlab_create_group_wiki_page' and description 'Create a group wiki page' indicate creation of new wiki content. The verb 'create' is characteristic of Write operations that modify data in a reversible manner.

How to control gitlab_create_group_wiki_page

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_create_group_wiki_page:

policy.json

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

gitlab_create_group_wiki_page 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.

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.
