AI agents call list_maintenance_policies 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 retrieves or queries existing maintenance policy data from Linode's infrastructure without creating, modifying, deleting, or executing any operations. It is a pure read operation, classified as low severity since unauthorized access to maintenance policy information poses minimal risk compared to write, execute, or destructive actions.
From the tool's definition Tool name is 'list_maintenance_policies' and description states 'List maintenance policies' — this is a query/retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_maintenance_policies 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 list_maintenance_policies:
{
"version": "1",
"default": "deny",
"tools": {
"list_maintenance_policies": {}
}
}list_maintenance_policies 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.
List maintenance policies. 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 list_maintenance_policies: 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.
list_maintenance_policies 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 list_maintenance_policies 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 list_maintenance_policies. 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.
list_maintenance_policies 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.
