Check if Go is installed and get its version
AI agents call check_go_installation to retrieve information from Hugo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a diagnostic check to retrieve the installation status and version of Go. It reads system state (presence of Go binary and its version output) without creating, modifying, deleting, executing arbitrary code, or causing side effects. This is a straightforward Read operation with minimal security risk.
From the tool's definition Tool name 'check_go_installation' and description 'Check if Go is installed and get its version' indicate a query operation that retrieves system information without modifying anything.
Documented attack patterns abuse exactly the kind of access check_go_installation gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Hugo, and nothing reaches the server without passing your rules. This is the rule we recommend for check_go_installation:
{
"version": "1",
"default": "deny",
"tools": {
"check_go_installation": {}
}
}check_go_installation is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check if Go is installed and get its version. It is categorised as a Read tool in the Hugo MCP Server, which means it retrieves data without modifying state.
Register the Hugo MCP server in PolicyLayer and add a rule for check_go_installation: 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 Hugo. Nothing to install.
check_go_installation 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 check_go_installation 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 check_go_installation. 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.
check_go_installation is provided by the Hugo MCP server (sunnycloudyang/hugo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Hugo, 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.
