AI agents call get_system_info_tool to retrieve information from Memory Shell Detector MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves system information without side effects. It is a read-only diagnostic operation typical of security scanning tools that need to understand the host environment. While it runs on a security-sensitive server (memory shell detector), the tool itself only gathers passive system data.
From the tool's definition Tool name 'get_system_info_tool' and description 'get current system environment info' (translated from Chinese) indicate retrieval of system metadata. No modification, deletion, code execution, or financial operations are described.
Documented attack patterns abuse exactly the kind of access get_system_info_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memory Shell Detector MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_system_info_tool:
{
"version": "1",
"default": "deny",
"tools": {
"get_system_info_tool": {}
}
}get_system_info_tool is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

获取当前系统环境信息. It is categorised as a Read tool in the Memory Shell Detector MCP MCP Server, which means it retrieves data without modifying state.
Register the Memory Shell Detector MCP server in PolicyLayer and add a rule for get_system_info_tool: 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 Memory Shell Detector MCP. Nothing to install.
get_system_info_tool 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 get_system_info_tool 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 get_system_info_tool. 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.
get_system_info_tool is provided by the Memory Shell Detector MCP server (ruoji6/memory-shell-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Memory Shell Detector MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
