List devices trusted for two-factor authentication
AI agents call list_trusted_devices 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 information about devices already configured for 2FA authentication. It has no side effects, does not modify any data, and does not execute commands or trigger external operations. It is a straightforward Read operation with minimal risk—unauthorized listing of trusted devices could expose security configuration details but does not directly compromise account access or resources.
From the tool's definition Tool name 'list_trusted_devices' and description 'List devices trusted for two-factor authentication' indicate a retrieval operation with no modification or execution of external systems. The verb 'list' is a query operation that only retrieves existing data.
Documented attack patterns abuse exactly the kind of access list_trusted_devices 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_trusted_devices:
{
"version": "1",
"default": "deny",
"tools": {
"list_trusted_devices": {}
}
}list_trusted_devices 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 devices trusted for two-factor authentication. 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_trusted_devices: 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_trusted_devices 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_trusted_devices 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_trusted_devices. 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_trusted_devices 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.
