Find all functions in the project that call the given function.
AI agents call find_project_callers to retrieve information from Unreal Project without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries a pre-built SQLite database of Unreal Engine project structure to retrieve call graph information. It is a read-only operation with no side effects—it searches and returns data about code relationships. No code is executed, no data is modified or deleted, and no external operations are triggered.
From the tool's definition Tool name 'find_project_callers' and description 'Find all functions in the project that call the given function' indicate a query operation that retrieves structural information from an indexed database without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Find all functions in the project that call the given function. It is categorised as a Read tool in the Unreal Project MCP Server, which means it retrieves data without modifying state.
Register the Unreal Project MCP server in PolicyLayer and add a rule for find_project_callers: 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 Project. Nothing to install.
find_project_callers 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 find_project_callers 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 find_project_callers. 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.
find_project_callers is provided by the Unreal Project MCP server (tumourlove/deprecated-unreal-project-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
