Remove project sharing with a group.
AI agents call unshare_project_with_group to permanently remove resources in GitLab MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Removing project sharing revokes access for an entire group irreversibly (or at least requires deliberate re-sharing to undo), affecting all group members' ability to access the project. This is a destructive access-control operation with a potentially large blast radius if misused, as it can cut off access for many users at once.

Attacks that exploit this kind of access
Remove project sharing with a group. It is categorised as a Destructive tool in the GitLab MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the GitLab MCP Server MCP server in PolicyLayer and add a rule for unshare_project_with_group: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches GitLab MCP Server. Nothing to install.
unshare_project_with_group is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the unshare_project_with_group rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for unshare_project_with_group. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
unshare_project_with_group is provided by the GitLab MCP Server MCP server (skmprb/gitlab-clone-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
