Connect Claude Code, Cursor, Windsurf, Claude Desktop, VS Code (Copilot), Antigravity, OpenCode, or any MCP-compatible AI agent directly to the Unreal Engine 5.7 Editor.

The v4 release ships 378 editor tools across 54 categories, plus 15 context resources and 14 workflow prompts via JSON-RPC 2.0 over Streamable HTTP — turning your AI assistant into a true co-developer for level building, gameplay scripting, cinematics, VFX, audio, networking, animation, UI, source control, automated testing, runtime debugging, modeling, material layers, Chaos destruction, and MetaHumans.

Key Features

378 Editor Tools across 54 categories — Actors, Materials, Material Layers/Graph, Blueprints, Sequencer, Landscapes, Foliage, Niagara, Audio, MetaSounds, MetaSound Graph, Physics, Chaos, Navigation, PCG, GAS, Enhanced Input, Networking, AI Behavior Trees, AnimGraph, StateTree, Control Rig, CommonUI, AI 3D/Image gen, Source Control, Test Authoring, Runtime Debug, PIE, Modeling, MetaHuman, plus the v4 Meta/Tasks discovery layer.

Catalog Mode — progressive tool disclosure cuts a fresh session’s tool-definition cost ~95% (~3K vs ~60K tokens) while keeping all 378 tools callable.

Tool Presets — Full / Scene Building / Gameplay / Minimal / Catalog. Switch instantly to manage AI context cost.

Multi-step tool scripts — run_tool_script runs a sequence (with variables and loops) as ONE all-or-nothing editor transaction.

Full Undo Support — every mutating operation is its own named editor transaction; scripts collapse into one undo step.

Universal AI Compatibility — Claude Code, Claude Desktop, Cursor, VS Code (Copilot), Windsurf, Antigravity, OpenCode, and any MCP-compatible client. Streamable HTTP + SSE — no vendor lock-in.

15 Context Resources — project data, level hierarchy, selected actors, performance stats, capability detection, undo history, and more.

60 Blueprint Tools — components, variables, wire nodes, set properties, full graph read-back, exec-path tracing, and cleanup.

Source Control Aware — works against any provider Unreal supports (Perforce, Git LFS, Plastic, Subversion).

Production-grade safety — bearer-token auth, origin allow-list, scope gating, structured errors, cooperative cancellation, dry-run, request size limits, tool-call timeouts, exception guards, session GC, DNS-rebinding defense.
