AI agents call list_sharegroup_tokens 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 token data associated with sharegroups. Although the description is incomplete ('List a user\'), the 'list_' prefix combined with the context of a token management function indicates this is a data retrieval operation with no side effects.
From the tool's definition Tool name contains 'list_' prefix and description indicates it retrieves sharegroup tokens for a user without modification. The term 'list' is a typical Read operation pattern.
Documented attack patterns abuse exactly the kind of access list_sharegroup_tokens 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_sharegroup_tokens:
{
"version": "1",
"default": "deny",
"tools": {
"list_sharegroup_tokens": {}
}
}list_sharegroup_tokens is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List a user\. 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_sharegroup_tokens: 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_sharegroup_tokens 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_sharegroup_tokens 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_sharegroup_tokens. 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_sharegroup_tokens 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.
