AI agents call sc_status to retrieve information from Unreal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the state of files in source control (e.g., committed, modified, untracked) and returns that information. It has no side effects, cannot execute operations, and cannot modify or delete data. It is a pure information retrieval function, clearly falling under the Read category with low severity since misuse would only expose source control metadata.
From the tool's definition Tool name 'sc_status' and description 'Query source control status of file(s)' indicates a read-only operation that retrieves status information without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Query source control status of file(s). It is categorised as a Read tool in the Unreal MCP Server, which means it retrieves data without modifying state.
Register the Unreal MCP server in PolicyLayer and add a rule for sc_status: 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_status is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the sc_status 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_status. 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_status is provided by the Unreal MCP server (sam-david/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
