WHAT IT DOES

What unpublish-element does on Mcp Dev

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

RISK

Why unpublish-element is rated Medium

Unpublishing content removes it from public visibility but is typically reversible (the content can be republished), so it falls under Write rather than Destructive. However, the blast radius is high because unpublishing content makes it immediately unavailable to end users, which could impact live production websites significantly if misused by an AI agent.

RECOMMENDED RULE

The rule that runs unpublish-element safely

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

unpublish-element Rate-limited

unpublish-element 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.
