Blueprint Graph Builder lets Python scripts create, read, lint and refactor Blueprints and UMG screens — from the editor, or headless in a build pipeline. The assets it produces are ordinary Blueprints with no runtime dependency on the plugin.
Open Tools › Blueprint Assistant in the editor, or drive the same engine from a script or your coding agent.
Pick a Blueprint and say what you want: “add an OpenAngle variable and print it on BeginPlay”. Or ask a question about how an existing Blueprint works.
See exactly what will change before anything is touched. Nothing runs until you press Apply.
The asset is backed up, the change is made, compiled and linted, and you get a diff of the graph. If something fails, it is corrected and shown to you again.
Eight areas, all available from Python, from the command line, and to your coding agent.
Variables, components, functions, events, dispatchers, macros, casts, Enhanced Input, comments and wires. Type specs cover structs, enums, classes and arrays.
Replicated and RepNotify variables with lifetime conditions; Server, Client and Multicast events, reliable or not.
Dump any Blueprint to readable text: every graph, node, pin, default value and link. Find nodes by title or GUID.
Insert nodes into an existing chain without losing what followed it, remove nodes and links, and rename variables everywhere they are used.
Unused variables, events with nothing connected, nodes that never run, casts and expensive calls on Tick, per-frame UMG bindings — written to a Markdown report.
Create Widget Blueprints; add, move and remove widgets; set widget and slot properties; expose widgets to the graph as variables.
A built-in MCP server lets Claude Code, Codex, Cursor and other MCP clients read, lint and build Blueprints in the open editor. Local only, nothing to install.
Describe a change in plain language and get a script that is run, checked and corrected. Connect your own Claude, OpenAI or OpenRouter key, or a local model through Ollama or LM Studio.
The assistant is optional. The plugin is complete without it.

| Engine | Status |
|---|---|
| UE 5.7 | Supported |
Supported platform: Windows 64-bit. Other engine versions are not claimed. The plugin needs the Python Editor Script Plugin, which it enables itself, and checks your subscription online once per editor session; after a successful check it keeps working offline for 7 days.
Email info@pedestel.com with your Unreal Engine version, the script you ran and the exact error text. Replies are sent in English or Turkish. Please do not send API keys or license keys you have not been asked for.
