AI agents call list_account_logins 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 historical login information from an account, which is a query operation with no side effects. While login history could be sensitive information, the tool itself performs only data retrieval. The blast radius of misuse is limited to unauthorized visibility of login records, not infrastructure changes or data loss.
From the tool's definition Tool is named 'list_account_logins' with description 'List account logins'. The verb 'list' indicates a read-only operation that retrieves and displays login history without modifying, executing, or deleting anything.

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_account_logins:
{
"version": "1",
"default": "deny",
"tools": {
"list_account_logins": {}
}
}list_account_logins is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List account logins. 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_account_logins: 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_account_logins 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_account_logins 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_account_logins. 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_account_logins 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.
