List files and directories in a Replit workspace
AI agents call list_files to retrieve information from Replit MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the file structure within a Replit workspace. It performs a query operation that reads data without creating, modifying, deleting, or executing anything. The blast radius of misuse is minimal—an AI agent listing files can at worst discover what files exist in a workspace, which is a reconnaissance-level read operation. No data is changed and no code is executed.
From the tool's definition Tool name 'list_files' and description 'List files and directories in a Replit workspace' indicate retrieval/enumeration of data with no modification or side effects.
Attacks that exploit this kind of access
List files and directories in a Replit workspace. It is categorised as a Read tool in the Replit MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Replit MCP Server 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 Replit MCP Server. 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 Replit MCP Server MCP server (nova-3951/replit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
