List files and directories in a project repository.
AI agents call list_repository_tree to retrieve information from Mcp Gitlab without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves repository structure information without creating, modifying, deleting, executing, or moving money. It is a standard read-only operation on version control metadata, presenting minimal risk even if invoked by an AI agent.
From the tool's definition Tool name 'list_repository_tree' and description 'List files and directories in a project repository' indicate a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
List files and directories in a project repository. It is categorised as a Read tool in the Mcp Gitlab MCP Server, which means it retrieves data without modifying state.
Register the Mcp Gitlab MCP server in PolicyLayer and add a rule for list_repository_tree: 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 Mcp Gitlab. Nothing to install.
list_repository_tree is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_repository_tree 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 list_repository_tree. 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.
list_repository_tree is provided by the Mcp Gitlab MCP server (wanadev/gitlab-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
