AI agents call list_files to retrieve information from Ruflo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs only a read operation on a virtual filesystem, retrieving and listing file metadata. There are no capabilities to modify, execute, or delete data. The blast radius is minimal—an agent could learn about available files but cannot act upon them through this tool alone. Classified as Read with low severity.
From the tool's definition Tool is named 'list_files' with description stating it 'List[s] all files in the virtual filesystem' and 'Returns file paths.' The action is purely informational—querying/retrieving file paths with no side effects.

Attacks that exploit this kind of access
List all files in the virtual filesystem. No parameters needed. Returns file paths. It is categorised as a Read tool in the Ruflo MCP Server, which means it retrieves data without modifying state.
Register the Ruflo 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 Ruflo. 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 Ruflo MCP server (ruvnet/ruflo). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_files is one line of Ruflo's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
