WHAT IT DOES

What read_blueprint_content does on Unreal-MCP

AI agents call read_blueprint_content to retrieve information from Unreal-MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why read_blueprint_content is rated Low

This tool retrieves and queries Blueprint data structures without side effects. The explicit 'read' verb and list of read-only data elements (event graph, functions, variables, components) clearly indicate information retrieval only. No creation, modification, deletion, or execution of game logic occurs. This is a straightforward Read category tool with minimal risk if an AI agent misuses it.

From the tool's definition Tool name explicitly includes 'read_' prefix and description states 'Read complete Blueprint content' with operations limited to retrieval: 'event graph, functions, variables, components' — all passive data inspection with no modification, deletion, or…

RECOMMENDED RULE

The rule that runs read_blueprint_content safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Unreal-MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For read_blueprint_content, this is the rule to start with:

read_blueprint_content Allowed

read_blueprint_content is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "read_blueprint_content": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Unreal-MCP, apply this rule, and every read_blueprint_content call is checked against it from then on.
