WHAT IT DOES

What stage_hide_message does on Propresenter

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

RISK

Why stage_hide_message is rated Medium

This tool hides a stage message in ProPresenter 7, which is a reversible UI state change (the message can be shown again). It modifies display state but does not delete data or execute arbitrary code, making Write the appropriate category. Severity is low as it only affects presentation display.

From the tool's definition Hide the current stage message

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs stage_hide_message safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Propresenter, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For stage_hide_message, this is the rule to start with:

stage_hide_message Rate-limited

stage_hide_message 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.

        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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