What sc_revert does on Unreal
AI agents use sc_revert to create or update resources in Unreal, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Unreal environment.
| Parameter | Type | Required | Description |

paths | array | Yes | File paths to revert |
Parameters from the server's own tool schema.
Why sc_revert is rated Medium
Reverting files in source control modifies the current state by restoring previous versions—a reversible Write operation rather than irreversible deletion. The blast radius depends on how many files and which files are reverted; an agent could revert critical files unintentionally, causing development disruption, but the action can be undone by reverting again or committing new changes.
From the tool's definition Tool name 'sc_revert' and description 'Revert file(s) in source control' indicate the tool reverts files to previous versions in a source control system.
Attacks that exploit this kind of access
The rule that runs sc_revert safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Unreal, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For sc_revert, this is the rule to start with:
sc_revert 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Unreal, apply this rule, and every sc_revert call is checked against it from then on.
Questions about sc_revert
Revert file(s) in source control. It is categorised as a Write tool in the Unreal MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
sc_revert accepts 1 parameter: paths. Required: paths. The full parameter table on this page comes from the server's own tool schema.
Register the Unreal MCP server in PolicyLayer and add a rule for sc_revert: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Unreal. Nothing to install.
sc_revert is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the sc_revert rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for sc_revert. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
sc_revert is provided by the Unreal MCP server (@jjpxdev/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
