What suspend_mysql_instance does on Linode MCP Server
AI agents call suspend_mysql_instance 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.
Why suspend_mysql_instance is rated Critical
Suspending a database instance makes it unavailable to applications, which is effectively an irreversible operational state change (until explicitly resumed) that can cause data access loss, service outages, and disruption to dependent applications. While not a permanent deletion, suspension of a production database has a high blast radius and the action is not trivially undone without additional steps.

The rule that runs suspend_mysql_instance safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Linode MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For suspend_mysql_instance, this is the rule to start with:
suspend_mysql_instance is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Linode MCP Server, apply this rule, and every suspend_mysql_instance call is checked against it from then on.
