AI agents call list_recent_files to retrieve information from Allcanuse without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves file metadata without modification, qualifying it as Read. Severity is medium because listing recent files exposes filesystem activity patterns and file locations, potentially leaking sensitive information about user workflows, but does not directly access file contents or modify data. Confidence is 0.75 due to missing tool description, though the name is sufficiently explicit.
From the tool's definition Tool name 'list_recent_files' indicates retrieval of file system metadata. Server description confirms it provides 'system probing' capabilities. No description provided but the name clearly suggests a query operation.
Documented attack patterns abuse exactly the kind of access list_recent_files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Allcanuse, and nothing reaches the server without passing your rules. This is the rule we recommend for list_recent_files:
{
"version": "1",
"default": "deny",
"tools": {
"list_recent_files": {}
}
}list_recent_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_recent_files. It is categorised as a Read tool in the Allcanuse MCP Server, which means it retrieves data without modifying state.
Register the Allcanuse MCP server in PolicyLayer and add a rule for list_recent_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 Allcanuse. Nothing to install.
list_recent_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_recent_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_recent_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_recent_files is provided by the Allcanuse MCP server (ra1nyxin/allcanuse-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Allcanuse, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
