Update group wiki page by slug.
AI agents use gitlab_update_group_wiki_page to create or update resources in Gitlab — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab environment.
This tool modifies wiki page content, which is reversible (can be edited again or reverted via GitLab's history). It does not delete data permanently or execute arbitrary code, so it falls under Write rather than Destructive or Execute.
From the tool's definition Tool name 'gitlab_update_group_wiki_page' and description 'Update group wiki page by slug' indicate modification of existing wiki content.

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_update_group_wiki_page:
{
"version": "1",
"default": "deny",
"tools": {
"gitlab_update_group_wiki_page": {
"limits": [
{
"counter": "gitlab_update_group_wiki_page_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}gitlab_update_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.
