Show which directories this server can access (security boundaries). No parameters required.
AI agents call list_allowed_directories to retrieve information from MCP Smart Filesystem Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about accessible directories—a read-only operation with no side effects. The blast radius of misuse is minimal since it only exposes information about security boundaries that are already enforced by the server's sandboxing mechanism. No data is created, modified, deleted, or executed.
From the tool's definition Tool name 'list_allowed_directories' and description 'Show which directories this server can access' indicate a query operation that retrieves security boundary information without modifying or executing anything.
Attacks that exploit this kind of access
Show which directories this server can access (security boundaries). No parameters required. It is categorised as a Read tool in the MCP Smart Filesystem Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Smart Filesystem Server MCP server in PolicyLayer and add a rule for list_allowed_directories: 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 Smart Filesystem Server. Nothing to install.
list_allowed_directories 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_allowed_directories 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_allowed_directories. 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_allowed_directories is provided by the MCP Smart Filesystem Server MCP server (lofcz/mcp-filesystem-smart). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
