AI agents call get_security_questions to retrieve information from Linode MCP Server 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 a list of available security questions from the Linode account. It performs a read-only operation that does not modify, execute, delete, or create any resources. The blast radius if misused is minimal—it only exposes the questions themselves, not answers or sensitive data.
From the tool's definition Tool name is 'get_security_questions' and description states 'Get available security questions', which is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access get_security_questions gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Linode MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_security_questions:
{
"version": "1",
"default": "deny",
"tools": {
"get_security_questions": {}
}
}get_security_questions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get available security questions. It is categorised as a Read tool in the Linode MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for get_security_questions: 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 Linode MCP Server. Nothing to install.
get_security_questions 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_security_questions 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_security_questions. 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_security_questions is provided by the Linode MCP Server MCP server (takashito/linode-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Linode MCP Server, 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.
