WHAT IT DOES

What messages_get does on Propresenter

AI agents call messages_get to retrieve information from Propresenter without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why messages_get is rated Low

This tool retrieves or queries message details with no side effects. It performs a read-only operation typical of data lookup functions. The low severity reflects minimal risk if misused by an AI agent, as retrieving message details cannot cause damage or unintended state changes.

From the tool's definition Tool name 'messages_get' and description 'Get details of a specific message' indicate data retrieval without modification. The verb 'Get' and the context within a presentation software (ProPresenter 7) suggest querying existing message data.

messages_get Allowed
