Documentation
Editor Automation RPC Gateway is an Unreal Editor plugin that runs a local MCP server, so AI agents can author Blueprints, materials, widgets, Niagara and more. These pages cover setup, the core model, and troubleshooting.
Looking for the RPC reference? The full ~1,200-RPC catalog is self-documenting and meant
for your agent, not this site — the agent browses it live through the
call tool
(call() for the index, call("namespace") for a page). See
Concepts for how that works.
Install & connect
Enable the plugin and point Claude Code, Cursor, Codex, Gemini or VS Code at it.
Quickstart
Your agent's first call() in five minutes.
Concepts
The single call tool, the three call modes, ports, jobs, and security.
Troubleshooting & FAQ
Connection problems, port conflicts, data privacy, engine-version questions.
Requirements
- An Unreal Engine 5.3–5.8 editor build with C++ plugin support.
- An MCP-capable AI agent (Claude Code, Cursor, Codex CLI, Gemini CLI, VS Code Copilot, Windsurf, Cline).
- The plugin is editor-only — it is not used in packaged game builds.
