List all files in workspace
AI agents call list_files to retrieve information from MCP File Manager without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays file metadata within the workspace directory. It performs no creation, modification, deletion, or execution of files—only enumeration. The operation is read-only and carries minimal risk even if invoked by an AI agent, as it cannot alter system state or access resources outside the designated workspace.
From the tool's definition Tool name 'list_files' and description 'List all files in workspace' indicates a query/retrieval operation with no data modification or side effects.

Attacks that exploit this kind of access
List all files in workspace. It is categorised as a Read tool in the MCP File Manager MCP Server, which means it retrieves data without modifying state.
Register the MCP File Manager MCP server in PolicyLayer and add a rule for list_files: 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 File Manager. Nothing to install.
list_files 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_files 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_files. 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_files is provided by the MCP File Manager MCP server (jantoebes/mcp-server-test). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
