What delete_group_wiki_page does on Gitlab Mcp
AI agents call delete_group_wiki_page 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.
Why delete_group_wiki_page is rated Critical
This tool irreversibly removes data (a wiki page) from a group workspace. Deletion is a destructive operation that cannot be undone through normal tool operations, making it more severe than Write (which is reversible). The impact is localized to a single wiki page rather than cascading across an entire group, preventing classification as 'critical', but it remains 'high' due to permanent data loss potential.
From the tool's definition Tool name contains 'delete'; description states 'Delete a wiki page from a group'. The action is irreversible—once a wiki page is deleted, it cannot be recovered without version control restoration.
Attacks that exploit this kind of access
The rule that runs delete_group_wiki_page 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_group_wiki_page, this is the rule to start with:
delete_group_wiki_page is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab Mcp, apply this rule, and every delete_group_wiki_page call is checked against it from then on.
