list_files
AI agents call list_files to retrieve information from Synology MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_files' tool retrieves or queries file listing data from the Synology NAS without modifying, deleting, or executing anything. This is a standard Read operation. The empty description lowers confidence slightly, but the tool name is unambiguous. Severity is low because file listing access is typically the least privileged information disclosure on a NAS.
From the tool's definition Tool name 'list_files' indicates retrieval/enumeration of file system data. No description provided, but naming convention and context within a NAS management server clearly suggests a query operation with no side effects.
Attacks that exploit this kind of access
list_files. It is categorised as a Read tool in the Synology MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Synology 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 Synology 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 Synology MCP Server MCP server (rafalr100/synology-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
