unsave_item · Reddirect MCP: Risk & Policy

WHAT IT DOES

What unsave_item does on Reddirect

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

WHY IT NEEDS A POLICY

Why unsave_item needs a policy

Unsaving an item modifies the user's saved list (a reversible action — the item can be saved again), with no deletion of actual content. This is a Write operation with low blast radius since it only affects the user's personal saved collection.

Verdict

unsave_item Rate-limited

unsave_item 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.
