List Drive spaces this token can enumerate. Returns up to two kinds:
AI agents call drive_spaces_list 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 is a read-only operation that queries and returns information about available Drive spaces. While it poses informational disclosure risk (an attacker could enumerate storage infrastructure), it does not modify, delete, execute, or commit financial transactions.
From the tool's definition Tool name 'drive_spaces_list' and description 'List Drive spaces this token can enumerate' indicate retrieval/enumeration of data with no modification.
Attacks that exploit this kind of access
List Drive spaces this token can enumerate. Returns up to two kinds:. It is categorised as a Read tool in the TrekMail MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TrekMail MCP Server MCP server in PolicyLayer and add a rule for drive_spaces_list: 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_spaces_list 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_spaces_list 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_spaces_list. 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_spaces_list 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.
