AI agents call delete_sharegroup_token to permanently remove resources in Linode MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible deletion of an authentication/access token. Once deleted, the token is no longer valid and must be recreated, making this a destructive action. The impact is high because token deletion could disrupt active integrations or access permissions for team members sharing resources, though it is not as critical as deleting entire infrastructure or data.
From the tool's definition delete_sharegroup_token — irreversibly deletes a sharegroup token, removing access credentials that cannot be easily restored without regeneration.
Documented attack patterns abuse exactly the kind of access delete_sharegroup_token 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 delete_sharegroup_token:
{
"version": "1",
"default": "deny",
"hide": [
"delete_sharegroup_token"
]
}delete_sharegroup_token disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a sharegroup token. It is categorised as a Destructive tool in the Linode MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Linode MCP Server MCP server in PolicyLayer and add a rule for delete_sharegroup_token: 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.
delete_sharegroup_token is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_sharegroup_token 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 delete_sharegroup_token. 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.
delete_sharegroup_token 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.
