Jutsu Unreal MCP
Jutsu Unreal MCP connects AI coding agents directly to Unreal Engine through the Model Context Protocol (MCP), providing structured local access to Unreal Editor authoring, inspection, and testing workflows.
Instead of exposing hundreds of MCP tools and schemas at once, Jutsu uses only 5 stable MCP tools backed by a searchable registry of 530 Unreal capabilities. Agents discover relevant operations through natural-language search, inspect exact contracts only when needed, execute changes, batch operations, and verify results.
The capability registry combines 527 dedicated Unreal capabilities with 3 generic reflection capabilities, extending access to reflected Unreal types, properties, metadata, and supported function calls while keeping specialized capabilities as the preferred path for complex operations.
Tested with Codex, Claude, and OpenCode.

Features
530 capabilities - 527 dedicated Unreal capabilities plus 3 generic reflection capabilities
Only 5 MCP tools exposed to the agent, keeping the MCP interface compact as functionality grows
Natural-language capability search with on-demand schema and contract discovery
Hybrid dedicated + reflection architecture for broad Unreal API coverage without replacing specialized workflows
Reflection-based discovery of native Unreal types and Blueprint-generated types
Structured inspection of classes, objects, properties, functions, structs, enums, metadata, parameters, and supported value shapes
Controlled reflected function invocation with Editor and PIE safety policies
Blueprint and graph authoring
Broad support across Materials, Animation, Control Rig, IK Rig, Niagara, PCG, UMG, Sequencer, MetaSound, GAS, StateTree, Enhanced Input, Smart Objects, Gameplay Interactions, AI, Navigation, Physics, Localization, Audio, World, Assets, and other Unreal systems
Native Unreal validation for types, graphs, pins, assets, ownership, compatibility, and editor state
Asset creation, editing, compilation, saving, reloading, and persistence verification
Ordered batch execution of up to 100 operations, including references to results from previous steps
Structured errors with expected/actual values, retryability, recovery information, related capabilities, and mutation state
Explicit safeguards for destructive and potentially unsafe operations
Stable asset, actor, world, graph, node, and pin identities instead of relying on editor selection
PIE lifecycle, diagnostics, and placed Functional Test support
Fully local MCP server running inside Unreal Editor
No API key, cloud service, Python environment, or paid external dependency required

Important Notes
Jutsu Unreal MCP is an editor development tool and does not add runtime functionality to packaged games.
The MCP server is intended for local use on the same trusted machine and is not designed to be exposed as a remote network service.
A compatible MCP client supporting Streamable HTTP is required and is not included with the plugin.
Generic reflection is intentionally controlled and does not provide unrestricted execution of arbitrary Unreal functions, Python, console commands, or C++ code.
