AI agents call get_system_info to retrieve information from Mcp Wsl Exec without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns system information about the WSL environment (such as OS version, hardware details, or configuration). It performs no side effects, makes no modifications, and executes no external operations. It is purely informational and read-only, making it a Read category tool with low severity.
From the tool's definition The tool name 'get_system_info' and description 'Get WSL system information' indicate a query operation that retrieves system metadata without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access get_system_info gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Wsl Exec, and nothing reaches the server without passing your rules. This is the rule we recommend for get_system_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_system_info": {}
}
}get_system_info is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Get WSL system information. It is categorised as a Read tool in the Mcp Wsl Exec MCP Server, which means it retrieves data without modifying state.
Register the Mcp Wsl Exec MCP server in PolicyLayer and add a rule for get_system_info: 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 Wsl Exec. Nothing to install.
get_system_info 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 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. 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 is provided by the Mcp Wsl Exec MCP server (spences10/mcp-wsl-exec). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Mcp Wsl Exec, 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.
