# MCPBlueprint

## Documentation

https://github.com/MZSH-UEPlugins/UEPluginDocs/blob/main/MCPBlueprint/README.md

---

MCPBlueprint is a self-contained Unreal Editor plugin that lets MCP-compatible AI clients inspect and edit Blueprints through a local HTTP endpoint.

## Highlights

- 55 tools for Blueprint discovery, members, functions, events, graphs, components, class defaults, User Defined Structs and Enums, asset lifecycle, compilation, and graph capture.

- Registry-backed node discovery and atomic declarative graph patches with preview, read-back, compilation, rollback, and automatic layout.

- Safety gates for high-impact member, signature, asset, Struct, and Enum changes.

- Explicit save behavior: editing tools do not silently persist assets.

- Version-matched Win64 Editor packages for Unreal Engine 5.2–5.8.

## Installation

Install the package that matches the exact Unreal Engine minor version under:

```text

<UE_5.x>/Engine/Plugins/Marketplace/MCPBlueprint/

```

After installation, restart the editor. MCPBlueprint is enabled automatically and starts its local MCP server by default. No project-side plugin entry or manual enable step is required.
