List directory contents with business file classification
AI agents call filesystem_list to retrieve information from Chicken Business Management MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays directory information without creating, modifying, deleting, or executing anything. It is purely informational. Severity is low because directory listing has minimal blast radius—it may expose file structure but does not alter data or trigger external operations. Confidence is high due to the explicit 'list' verb and clear read-only semantics.
From the tool's definition Tool name is 'filesystem_list' and description states 'List directory contents with business file classification'. The verb 'list' and action of reading directory contents without modification indicates a read-only operation.
Attacks that exploit this kind of access
List directory contents with business file classification. It is categorised as a Read tool in the Chicken Business Management MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Chicken Business Management MCP Server MCP server in PolicyLayer and add a rule for filesystem_list: 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 Chicken Business Management MCP Server. Nothing to install.
filesystem_list 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 filesystem_list 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 filesystem_list. 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.
filesystem_list is provided by the Chicken Business Management MCP Server MCP server (psyger02/mcpserver). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
