list_file_paths
AI agents call list_file_paths to retrieve information from File Search Tool without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs directory listing and path enumeration, which are read-only operations with no side effects. No data is created, modified, deleted, or executed. The blast radius if misused is limited to information disclosure.
From the tool's definition Tool is part of a 'File Search Tool' server described as enabling 'file system search and inspection, including directory listing'.
Attacks that exploit this kind of access
list_file_paths. It is categorised as a Read tool in the File Search Tool MCP Server, which means it retrieves data without modifying state.
Register the File Search Tool MCP server in PolicyLayer and add a rule for list_file_paths: 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 File Search Tool. Nothing to install.
list_file_paths 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_file_paths 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_file_paths. 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_file_paths is provided by the File Search Tool MCP server (rjtpp/mcp-server-file-search-tool). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
