putplaylist · Revel Digital MCP Server MCP: Risk & Policy

WHAT IT DOES

What putplaylist does on Revel Digital MCP Server

AI agents use putplaylist 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 putplaylist needs a policy

This tool replaces an existing playlist with new data. While it modifies/overwrites content, it is a reversible write operation (the playlist can be replaced again with the original). However, replacing a playlist could disrupt active digital signage displays, giving it a high severity. It falls under Write rather than Destructive because the playlist record still exists — it is updated/replaced, not deleted.

From the tool's definition 'Put a playlist. Replaces a playlist with the one provided.'

putplaylist Rate-limited

putplaylist 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.
