Overview of the latest build: error count, warning count, duration.
AI agents call get_build_summary to retrieve information from Unreal Editor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns aggregated build statistics (error count, warning count, duration) without creating, modifying, executing, or deleting any data. It is a read-only diagnostic tool that retrieves existing build information. The low severity reflects that misuse would only expose non-sensitive build metadata with no blast radius for system state or data integrity.
From the tool's definition Tool name 'get_build_summary' and description 'Overview of the latest build: error count, warning count, duration' indicate retrieval of build status metrics with no modification or execution capability.
Attacks that exploit this kind of access
Overview of the latest build: error count, warning count, duration. It is categorised as a Read tool in the Unreal Editor MCP Server, which means it retrieves data without modifying state.
Register the Unreal Editor MCP server in PolicyLayer and add a rule for get_build_summary: 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 Editor. Nothing to install.
get_build_summary 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 get_build_summary 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 get_build_summary. 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.
get_build_summary is provided by the Unreal Editor MCP server (tumourlove/deprecated-unreal-editor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
