AI agents call list_ipv6_ranges 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 lists IPv6 ranges from Linode infrastructure without creating, modifying, or deleting any resources. It is a simple informational query with no side effects, making it a Read category risk with low severity since misuse would only expose existing configuration data rather than enabling destructive or financial actions.
From the tool's definition Tool name 'list_ipv6_ranges' and description 'List all IPv6 ranges' indicate a read-only query operation that retrieves information without modification.
Documented attack patterns abuse exactly the kind of access list_ipv6_ranges 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_ipv6_ranges:
{
"version": "1",
"default": "deny",
"tools": {
"list_ipv6_ranges": {}
}
}list_ipv6_ranges 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 all IPv6 ranges. 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_ipv6_ranges: 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_ipv6_ranges 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_ipv6_ranges 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_ipv6_ranges. 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_ipv6_ranges 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.
