WHAT IT DOES

What mark_event_as_seen does on Linode MCP Server

RISK

Why mark_event_as_seen is rated Medium

This operation modifies metadata associated with an event (marking it as 'seen' rather than 'unseen'), which constitutes a write operation. The severity is low because marking events as seen has minimal blast radius—it only affects visibility/notification state and carries no risk to infrastructure, data integrity, or financial systems.

From the tool's definition The tool marks an event as seen, which updates the state of an event record without deleting or destroying data. The action is reversible (can be unmarked or re-marked).
