AI agents call drive_folder_tree to retrieve information from TrekMail MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns folder information (ids, names, parent relationships, colors) with no side effects—no creation, modification, deletion, or execution of code. It is a straightforward read operation for building folder hierarchies or navigation structures. The low severity reflects minimal risk from misuse, as it only exposes folder metadata, not sensitive content within folders.
From the tool's definition Tool name 'drive_folder_tree' and description 'Flat list of every folder in the space (id + name + parent_id + color)' indicates a retrieval operation that returns structural metadata about folders without modification.

Register the TrekMail MCP Server MCP server in PolicyLayer and add a rule for drive_folder_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 TrekMail MCP Server. Nothing to install.
drive_folder_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 drive_folder_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 drive_folder_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.
drive_folder_tree is provided by the TrekMail MCP Server MCP server (trekmail/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
