List files in the shared workspace
AI agents call list_workspace_files to retrieve information from MCP Developer Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a directory listing operation with no side effects. It retrieves information about files in the workspace but does not create, modify, delete, or execute anything. The blast radius of misuse is minimal—an agent could enumerate files but cannot alter them. This is a classic Read category tool.
From the tool's definition Tool name 'list_workspace_files' and description 'List files in the shared workspace' indicate a read-only operation that retrieves file listing without modification.
Attacks that exploit this kind of access
List files in the shared workspace. It is categorised as a Read tool in the MCP Developer Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Developer Server MCP server in PolicyLayer and add a rule for list_workspace_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 Developer Server. Nothing to install.
list_workspace_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_workspace_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_workspace_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_workspace_files is provided by the MCP Developer Server MCP server (ra86-dev/mcpdockershell). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
