postschedule · Revel Digital MCP Server MCP: Risk & Policy

WHAT IT DOES

What postschedule does on Revel Digital MCP Server

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

WHY IT NEEDS A POLICY

Why postschedule needs a policy

The tool creates a new schedule entry in the digital signage system. This is a reversible write operation (the schedule can be deleted later). Misuse could result in unauthorized content being scheduled for display, but it does not destroy existing data or involve financial transactions.

Verdict

postschedule Rate-limited

postschedule 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.
