WHAT IT DOES

What resume_postgresql_instance does on Linode MCP Server

AI agents use resume_postgresql_instance to create or update resources in Linode MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Linode MCP Server environment.

RISK

Why resume_postgresql_instance is rated Medium

Resuming a suspended database instance restarts/reactivates it, which is a state change that modifies the resource. This is reversible (it can be suspended again), so it falls under Write rather than Execute or Destructive. However, it has high severity because reactivating a database instance can incur costs and affect infrastructure state.

resume_postgresql_instance stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
