WHAT IT DOES

What suspend_postgresql_instance does on Linode MCP Server

AI agents invoke suspend_postgresql_instance to trigger actions in Linode MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

RISK

Why suspend_postgresql_instance is rated High

Suspending a database instance triggers an external operational state change that interrupts service availability. It is not purely destructive (data is not deleted) but it executes a significant operational action on infrastructure that can cause downtime and service disruption, making it Execute with high severity due to the blast radius of taking a production database offline.

RECOMMENDED RULE

The rule that runs suspend_postgresql_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_postgresql_instance, this is the rule to start with:

suspend_postgresql_instance Rate-limited

suspend_postgresql_instance stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

RATE-LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Linode MCP Server, apply this rule, and every suspend_postgresql_instance call is checked against it from then on.
