AI agents call fm_list_directory to retrieve information from K-Personal MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves directory contents without side effects. It performs a simple read operation analogous to 'ls' or 'dir' commands. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal—an agent could enumerate files but cannot modify, delete, or execute them. Classified as Read with low severity.
From the tool's definition Tool name 'fm_list_directory' and description translated from Korean: 'Shows a list of files/subfolders in the specified folder.' This is a directory listing operation with no modification or execution capability.

Register the K-Personal MCP server in PolicyLayer and add a rule for fm_list_directory: 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 K-Personal MCP. Nothing to install.
fm_list_directory 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 fm_list_directory 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.
