Delete a GitLab project
AI agents call delete_repository 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.
Deleting a repository is a destructive action that cannot be undone—it permanently removes all code, history, issues, merge requests, and associated data. This is more severe than individual file or branch deletions because it eliminates an entire project.
From the tool's definition Tool name 'delete_repository' and description 'Delete a GitLab project' indicate irreversible deletion of an entire repository and all its contents.
Attacks that exploit this kind of access
Delete a GitLab project. 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 delete_repository: 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.
delete_repository 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 delete_repository 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 delete_repository. 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.
delete_repository is provided by the GitLab MCP Server MCP server (lucky-dersan/gitlab-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
