voxel-plugin-tools

Voxel Plugin 2 for ue-mcp: 43 native actions in a voxel category covering worlds, stamps, sculpting, layer queries, voxel assets, voxel PCG nodes and graph authoring.

Install

ue-mcp plugin install voxel

This adds the plugin to ue-mcp.yml, copies the VoxelPluginTools C++ module into Plugins/, and installs three skills into .claude/skills/. Rebuild the project, then restart ue-mcp.

Requirements

ue-mcp 1.3.10-beta.13 or later (enforced by minServerVersion; prerelease servers included) with a bridge at ABI 2 or later (ue-mcp deploy)
Voxel Plugin 2 enabled in the .uproject; built and tested against the dev branch
Unreal Engine 5.8
Voxel's engine shader hooks applied, for Voxel materials to render (voxel_shader_hooks_status reports them and names the fix)

Usage

voxel(action="voxel_asset_create", type="height_graph", name="HG_Terrain", packagePath="/Game/Terrain")
voxel(action="voxel_asset_create", type="mega_material", name="MM_Terrain", packagePath="/Game/Terrain")
voxel(action="voxel_world_spawn", label="World", megaMaterial="/Game/Terrain/MM_Terrain")
voxel(action="voxel_actor_spawn", kind="stamp", label="Terrain")
voxel(action="voxel_stamp_set", actorPath="<from the spawn>", kind="height_graph", asset="/Game/Terrain/HG_Terrain")
voxel(action="voxel_query_layer", points=[{x: 0, y: 0}])

Each action's parameters are a typed contract declared next to its C++ registration; tools(action="describe", category="voxel", method=...) shows it, and calls that break it are refused.

Skills

Skill (installed name)	Covers
`voxel-plugin-tools-voxel-terrain`	Shader-hook preflight, layer stacks, the voxel world, height and volume stamps (spline points included), surfaces and the mega material, sculpting, verifying with layer queries
`voxel-plugin-tools-voxel-graphs`	Authoring voxel graphs: node types, wiring, parameters, functions and function libraries, graph instances, T3D copy, debugging graph output
`voxel-plugin-tools-voxel-pcg`	PCG on voxel terrain: the Voxel Sampler, surface-type scatter, partitioned and runtime-generated components, regeneration, stamps spawned from PCG

Conventions

Actors are addressed by actorPath (stable) or actorLabel, not both; stamp actors relabel themselves, so prefer the path.
Rotations are {pitch,yaw,roll}, vectors {x,y,z} in centimetres, every component given.
Content packages an action dirties are saved before it replies (autoSaved in the result; asset and graph edits also report saved); save: false skips it. Levels are left to you.
Existing assets are never overwritten.
Non-finite numbers in results are reported as null.

Develop

See CONTRIBUTING.md. npm run check validates the manifest against the host schema and matches it to the C++ registrations and their contracts; node scripts/live-test.mjs runs every action against a live editor.
