Documentation

AI-powered 3D modeling tools for Unity ProBuilder. Enables AI assistants to create and manipulate editable meshes through natural language commands. Create primitive shapes, extrude faces, bevel edges, apply materials, merge objects, and perform advanced mesh operations like bridging and subdivision. Supports semantic face selection by direction (up, down, left, right) for intuitive editing. Perfect for rapid level prototyping and procedural geometry generation. Built on top of the AI Game Developer platform.

RQL (no extension tools)

Since Unity-MCP 1.0.0 this package adds no MCP tools: it contributes an RQL module, so agents use rql-query / rql-mutate (the unity-rql skill carries the full "ProBuilder" guide with examples). M below stands for probuilder | get meshes | where gameObject.name == "Crate".

Former tool	RQL
`probuilder-create-shape`	`probuilder \| call CreateShape("Cube", "Crate", "(2, 1, 2)", "(0, 0.5, 0)")` (type, name, size, position, rotation, parent)
`probuilder-create-poly-shape`	`probuilder \| call CreatePolyShape(["(0, 0)", "(4, 0)", "(4, 3)"], 0.5, "Floor")` (points, height, name, position, flipNormals, parent)
`probuilder-get-mesh-info`	`M \| select faceCount vertexCount edgeCount bounds directions materials`, `M \| get faces \| select index direction center edges`, `probuilder.vertices($, start, count)`
`probuilder-extrude`	`M \| call Extrude(probuilder.facing($, "Up"), 0.5)` (faces, distance, method)
`probuilder-delete-faces`	`M \| call DeleteFaces([0, 2])`
`probuilder-set-face-material`	`M \| call SetFaceMaterial(probuilder.facing($, "Up"), "Assets/Materials/Grass.mat")`
`probuilder-flip-normals`	`M \| call FlipNormals([0])` (all faces when omitted)
`probuilder-bevel`	`M \| call Bevel(probuilder.edges($, [4]), 0.1)`
`probuilder-bridge`	`M \| call Bridge(probuilder.openEdges($)[0], probuilder.openEdges($)[2])`
`probuilder-connect-edges`	`M \| call ConnectEdges(probuilder.edges($, [4]))`
`probuilder-subdivide-edges`	`M \| call SubdivideEdges([[0, 1]], 2)`
`probuilder-set-pivot`	`M \| call SetPivot("Center")` / `SetPivot("FirstVertex")` / `SetPivotAt("(0, 0, 0)")`
`probuilder-merge-objects`	`probuilder \| call Merge([ref("ProBuilderMesh#…"), ref("GameObject#…")], true)`

Faces are index lists ([0, 1]), edges vertex index pairs ([[0, 1]]); probuilder.facing($, "Up") replaces the former faceDirection parameter. Every call validates its input first and is undoable.
