AI agents call search_concepts to retrieve information from Unreal Engine Knowledge Graph MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though search_concepts only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access

Register the Unreal Engine Knowledge Graph MCP Server MCP server in PolicyLayer and add a rule for search_concepts: 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 Engine Knowledge Graph MCP Server. Nothing to install.
search_concepts 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 search_concepts 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 search_concepts. 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.
search_concepts is provided by the Unreal Engine Knowledge Graph MCP Server MCP server (yarnovo/unreal-engine-knowledge-graph-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
