Gamedev All-in-One MCP

One server that drives Roblox Studio, Unity, Unreal and Blender at once — create the object in one engine, then replicate it in the others without switching tools.

LABSCO SUMMARY

Four engines, one vocabulary.

The physics tools are deliberately parallel across engines — gravity, rigid bodies, constraints, raycast and force appear in the same shape for all four — which is what makes "build it here, replicate it there" a single request rather than four translations. It is alpha and AGPL-3.0, both worth knowing before it goes near a commercial project.

What it is

An MCP server with four engine connectors behind it, each talking to a plugin running inside the editor: a Luau plugin for Roblox over HTTP, a C# EditorWindow for Unity, a C++ plugin for Unreal, and a Python addon for Blender, all over TCP. The connectors auto-reconnect, and a dashboard on port 3100 shows what is currently attached.

What you get

  • Foundation — project_init, inspect_project, doctor to validate the environment and connectors, list_capabilities for tools and connector status
  • Roblox, 20 tools — roblox_run_code, roblox_create_workspace_part, script work with roblox_get_script_source, roblox_set_script_source, roblox_edit_script_lines and roblox_grep_scripts, instance CRUD with roblox_create_instance, roblox_delete_instance, roblox_set_property, roblox_clone_instance, roblox_reparent_instance, and queries via roblox_search_instances and roblox_get_file_tree
  • Unity, 15 tools — unity_get_hierarchy, unity_create_gameobject, unity_add_component, unity_set_component_property, unity_set_transform, unity_play_mode, unity_execute_menu_item and the rest
  • Unreal, 15 tools — unreal_get_world_outliner, unreal_spawn_actor, unreal_set_actor_transform, unreal_get_blueprint, unreal_run_python, unreal_play_mode, unreal_get_viewport_screenshot
  • Blender, 13 tools — blender_get_scene, blender_create_object, blender_set_material, blender_set_transform, blender_run_python, blender_export
  • Physics in every engine, with the same shape each time: gravity, rigid bodies, constraints, raycasting and applied force — unity_apply_force, unreal_raycast, blender_bake_physics, roblox_simulate_physics and their siblings
  • 67 tools in total across 12 modules, plus a web dashboard with real-time SSE monitoring

Requirements

No account and no key, but each engine needs its plugin installed and its editor open — the server talks to a live editor, not to project files. Node.js 20+; clone the repository, npm install, npm run build, then point the client at dist/index.js. Ports are fixed per engine: Roblox on 3002, Unity on 7890, Unreal on 55557, Blender on 9876, and the dashboard on 3100. Run the environment check first if a connector is silent. Package gamedev-all-in-one at 0.1.0, AGPL-3.0, and the project marks itself alpha.

Setup effort

Build from source — git clone https://github.com/dmae97/gamedev-all-in-one-mcp.git
