list_files
AI agents call list_files to retrieve information from ERPNext MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to list or enumerate files, which is a read-only query operation with no side effects. While confidence is moderate due to the empty description, the name and context of sibling tools strongly indicate retrieval functionality. Even if it exposes file metadata or paths, this remains a Read operation with low blast radius unless it reveals highly sensitive data structures.
From the tool's definition Tool name 'list_files' indicates a retrieval operation. The server description mentions 'retrieval' and 'query' as read operations.
Attacks that exploit this kind of access
list_files. It is categorised as a Read tool in the ERPNext MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ERPNext 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 ERPNext 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 ERPNext MCP Server MCP server (yazelin/erpnext-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
