Unreal AI Connection

Drive Unreal Engine 5.7 from any MCP-compliant client over a local TCP socket.

151 tools total. Zero pixel-clicking. ~50ms round-trip.

Live demo: an MCP client procedurally builds a city in Unreal Engine 5.7, places Niagara FX, and orbits a camera

Live capture — an MCP client builds the scene, places Niagara FX (spawn_niagara_at_location), and orbits a camera, entirely over the local TCP socket. Reproduce with scripts/capture_demo_gif.py.

Native C++ handlers — not Python Remote Execution. ~50 ms round-trips across 149 tools · 637 tests · MIT · works with any MCP-compliant client (Claude Code, Cursor, Cline, Codex, Gemini, Continue, Windsurf, Zed, …).

The suite now spans inspection and authoring — read existing assets and create them: actors, levels, data tables/assets, Blueprints (incl. K2 graph nodes), material graphs, Niagara FX, Level Sequence cinematics (camera cuts, audio, visibility), and Movie Render Queue renders — all over the same socket.

⭐ If this saves you time, a star helps other devs find it.

Authoring high-quality assets: see docs/ASSET-PIPELINE-BLENDER.md.

Install (one paste, any client)

Every route below only wires the stdio bridge. You must separately install the UE 5.7 plugin into your project's Plugins/ folder and launch the editor (it binds 127.0.0.1:18888). See docs/setup/README.md for the prerequisite, and docs/DISTRIBUTION.md for how this is published.

Claude Code — paste the owner/repo, no clone needed:

/plugin marketplace add NAJEMWEHBE/unreal-ai-connection
/plugin install unreal-ai-connection@unreal-ai-connection

Cursor — one-click deeplink. Base64-encode your machine's bridge path into this template:

cursor://anysphere.cursor-deeplink/mcp/install?name=unreal-ai-connection&config=<BASE64>

where <BASE64> is base64 of {"command":"python3","args":["/ABSOLUTE/PATH/TO/bridge/unreal_ai_connection_bridge.py"]} (on Windows use "command":"py" if python3 is not on PATH). Manual fallback — .cursor/mcp.json:

{ "mcpServers": { "unreal-ai-connection": { "command": "python3", "args": ["/ABSOLUTE/PATH/TO/bridge/unreal_ai_connection_bridge.py"] } } }

VS Code — install deeplink (URL-encode the JSON for your path):

vscode:mcp/install?<URL-ENCODED {"name":"unreal-ai-connection","command":"python3","args":["/ABSOLUTE/PATH/.../bridge/unreal_ai_connection_bridge.py"]}>

Windows: all snippets use python3; if that's not on PATH use the py launcher instead ("command": "py"). The .claude-plugin/mcp-config.json marketplace path uses python3 for cross-platform consistency — Windows users without python3 should use the manual per-client recipe in docs/setup/ with py.

Every other client — copy-paste recipe per client:

unreal-ai-connection
