Get a detailed listing of all files and directories in a specified path.
AI agents call list_directory to retrieve information from Server Sequential Thinking without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation on the file system. It retrieves information about files and directories (similar to 'ls' or 'dir' commands) without creating, modifying, deleting, or executing anything. The blast radius is minimal since it only exposes existing directory structure metadata. Confidence is high due to the clear read-only nature of directory listing operations.
From the tool's definition Tool description states 'Get a detailed listing of all files and directories in a specified path' — a query operation that retrieves and lists directory contents without modification.

Attacks that exploit this kind of access
Get a detailed listing of all files and directories in a specified path. It is categorised as a Read tool in the Server Sequential Thinking MCP Server, which means it retrieves data without modifying state.
Register the Server Sequential Thinking MCP server in PolicyLayer and add a rule for 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 Server Sequential Thinking. Nothing to install.
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 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.
Set action: deny in the PolicyLayer policy for list_directory. 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_directory is provided by the Server Sequential Thinking MCP server (@modelcontextprotocol/server-sequential-thinking). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
