mcp_call_mac_system_profiler
AI agents call mcp_call_mac_system_profiler to retrieve information from Mcp My Mac without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
System profiler tools retrieve hardware and software configuration data without modifying anything. This is a Read operation. Severity is medium rather than low because system profiler output can reveal sensitive information (serial numbers, hardware identifiers, installed software versions) that could aid in reconnaissance or supply chain attacks, though the tool itself performs no destructive or executable actions.
From the tool's definition Tool name 'mac_system_profiler' indicates it calls macOS system profiler to retrieve system information; description is empty but sibling tools (conda_info, gpu_available) suggest diagnostic/informational purpose rather than modification or execution.
Attacks that exploit this kind of access
mcp_call_mac_system_profiler. It is categorised as a Read tool in the Mcp My Mac MCP Server, which means it retrieves data without modifying state.
Register the Mcp My Mac MCP server in PolicyLayer and add a rule for mcp_call_mac_system_profiler: 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 Mcp My Mac. Nothing to install.
mcp_call_mac_system_profiler 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 mcp_call_mac_system_profiler 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 mcp_call_mac_system_profiler. 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.
mcp_call_mac_system_profiler is provided by the Mcp My Mac MCP server (zhongmingyuan/mcp-my-mac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
