What fs_list_allowed_directories does on LocalAnt
AI agents call fs_list_allowed_directories to retrieve information from LocalAnt without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why fs_list_allowed_directories is rated Low
This tool queries and returns filesystem access policies—a metadata/configuration read operation. It has no side effects, cannot modify files or execute commands, and cannot delete or move data. It carries minimal risk as it merely exposes already-approved access rules. Confidence is high because the name and function are unambiguous.
From the tool's definition Tool name 'fs_list_allowed_directories' and description 'List filesystem access policy' indicate retrieval of policy information without modification or execution. The verb 'list' is a read-only operation.
Attacks that exploit this kind of access
The rule that runs fs_list_allowed_directories safely
PolicyLayer is an MCP gateway: it sits between your AI agents and LocalAnt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fs_list_allowed_directories, this is the rule to start with:
fs_list_allowed_directories is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect LocalAnt, apply this rule, and every fs_list_allowed_directories call is checked against it from then on.
