 "title": "Let Codex or Claude Code edit an Unreal project via MCP",
 "page_title": "How to let Codex or Claude Code edit an Unreal project via MCP with Uebox",
 "summary": "Connect an external coding agent to a running Unreal Editor so it can call engine tools.",
 "who": "An Unreal developer who already uses Codex, Claude Code, or Cursor and wants that agent to change levels, Blueprints, or C++ in the open project.",
 "problem": "Switching between an AI coding assistant and the Unreal Editor means copying work by hand, and the assistant cannot see or edit engine assets.",
 "outcome": "The external agent reads and writes engine assets through UE Box tools, and UE Box lists every new, changed, or deleted item for the round.",
 "steps": [
  "Download the installer from the Releases page of the repo and install UE Box on Windows.",
  "In UE Box, go to 项目库 (project library), choose 导入项目, select your .uproject, install the UnrealAgentLink plugin when asked, then click 打开项目.",
  "Follow the MCP guide at https://uebox.ai/guide/mcp and copy the local token it requires.",
  "Add UE Box as an MCP server in Codex, Claude Code, or Cursor using that token. The MCP connection is writable by default.",
  "Ask the agent for one small change, then check the change list in UE Box and use the re-read option to compare the editor state."
 ],
 "agent_prompt": "Using the UE Box MCP server in the ueboxai/uebox repo, count the light actors in the level <level name> and report the count. Then list the tool calls used and confirm the editor project is still open with no unexpected changes.",
 "agents": [
  "codex",
  "claude-code",
  "cursor"
 ],
 "difficulty": "Intermediate",
 "time": "45 minutes",
 "basis": "readme",
 "caveat": "The README says MCP only connects from the local machine and needs a token, so a remote or cloud agent cannot reach the editor this way.",
 "category": "Software and DevOps",
 "tags": [
  "Software and DevOps"
 ],
 "lang": "typescript",
 "requirements": [
  "A Windows PC for the installer, with Unreal Engine 5.0 to 5.8 and a .uproject file",
  "An API key from a model provider that supports tool calling, or a local model such as Ollama or LM Studio",
  "Permission to install the UnrealAgentLink plugin into your Unreal project"
