AI agents call mcp_file_list_directory to retrieve information from ShowDoc MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs directory enumeration—a read-only query that retrieves file system metadata without modifying, executing, or deleting anything. It is analogous to 'ls' or 'dir' commands, which are informational only. Even in an AI agent context, misuse would be limited to information disclosure about directory structure.
From the tool's definition Tool name and description indicate it 'lists files and subdirectories in a directory' (mcp_file_list_directory / 列出目录中的文件和子目录), a pure retrieval operation with no side effects.

Yes. Add a rate_limit block to the mcp_file_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.
