v1.6.0 — Low-poly character tools

• Mesh painting: paint_texture, paint_faces and get_texture now target mesh faces too. The UV
  polygon is clipped pixel-exact, and space: "world" gradients are computed per texel. On meshes, a
  direction name ("up") selects every face pointing that way. inspect_uv reports mesh UV problems
  and texel density.
• unwrap_mesh: connected mesh faces merge into islands. Seam control, per-part density
  (density_scale), and existing paint carried over to the new layout.
• edit_mesh: Blockbench's extrude, inset, solidify, loop cut, merge, dissolve, create/invert face
  and split tools, plus subdivide, bevel, delete and merge_meshes. Steps chain with
  select: "previous".
• add_loft: box, round or custom-profile limbs and tubes from rings. transform_mesh: taper, bend,
  twist, scale, rotate, move, smooth, jitter.
• bake_texture: light direction, ray-traced ambient occlusion, convex edge highlights and concave
  crease shadows, height gradient and grain. The result snaps to a hue-shifted pixel-art ramp derived
  from each texel's own color.
• palette: hue-shifted ramps, color extraction, locking to auto / fixed palettes / ramps (with
  dithering).
• compare_reference: silhouette IoU against a reference image, aspect ratio and per-band width
  difference, overlay image. project_reference: projects the reference onto visible, unoccluded
  texels.
• record_build: captures a frame from a fixed camera on every edit and writes an animated GIF at
  the end.
• Fix: add_mesh_primitive generated cylinders, cones, pyramids, tori and planes inside out, which
  made extrude go inward. Cylinder and cone caps with more than 4 sides (n-gons) also failed; they are
  now generated as triangle fans.

Installation

1. Download blockbench_mcp.js and mcp-server.js (or unzip the archive). No npm install needed: the server is bundled with its dependencies.
2. Blockbench → File → Plugins → Load Plugin from File → blockbench_mcp.js.
3. Add it to Claude:

claude mcp add --scope user blockbench -- node /path/to/mcp-server.js

Requires Node.js 18+.
