WHAT IT DOES

What rollback-element-version does on Mcp Dev

AI agents use rollback-element-version 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 rollback-element-version is rated Medium

Rolling back to a previous version is a write/update operation that overwrites current state with a prior version. It is reversible in principle (you can roll back again or re-apply changes), so it falls under Write rather than Destructive. However, it does overwrite the current state, which could cause unintended data loss if misused, warranting a medium severity.

From the tool's definition 'Rollback an element to a specific version' - restores a previous state

RECOMMENDED RULE

The rule that runs rollback-element-version 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 rollback-element-version, this is the rule to start with:

rollback-element-version Rate-limited

rollback-element-version 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.
