Manage file and directory permissions on macOS. Get/set POSIX permissions (chmod), ownership (chown), ACL entries, check current-user access, and find world-writable files.
AI agents invoke pilotgentic_file_permissions_manager to trigger actions in PilotGentic. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool modifies file system permissions and ownership (chmod/chown), which are privileged system operations. While not purely destructive (data isn't deleted), changing permissions can make files world-writable, remove access controls, or enable privilege escalation — making it an Execute-class tool with high severity.

Attacks that exploit this kind of access
Manage file and directory permissions on macOS. Get/set POSIX permissions (chmod), ownership (chown), ACL entries, check current-user access, and find world-writable files. It is categorised as a Execute tool in the PilotGentic MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the PilotGentic MCP server in PolicyLayer and add a rule for pilotgentic_file_permissions_manager: 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 PilotGentic. Nothing to install.
pilotgentic_file_permissions_manager is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the pilotgentic_file_permissions_manager 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 pilotgentic_file_permissions_manager. 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.
pilotgentic_file_permissions_manager is provided by the PilotGentic MCP server (@pilotgentic/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
