Make a 3D model animation-ready — add a humanoid skeleton and skin weights to an existing GLB, or generate a rigged avatar from text/images in one call. Use when you or the user want to rig a mesh, auto-rig a GLB, make a model animatable, get a character that plays idle/walk animations, or go from prompt straight to a rigged avatar. Covers "rig this GLB", "make it animatable", "text to rigged avatar". Paid lane ($0.20 / $0.45 USDC via x402).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Auto-Rig — skeleton + skin weights for animation Two paths, depending on whether you already have a mesh. ## Tools Both on the three.ws MCP server (`@three-ws/mcp-server`). ### `rig_mesh` — rig an existing GLB ($0.20 USDC) Auto-rig a static GLB: adds a humanoid skeleton and per-vertex skin weights via the three.ws rig pipeline (Make-It-Animatable by default). | Param | Required | Notes | | --- | --- | --- | | `glb_url` | yes | http(s) URL to the static GLB to rig — e.g. the `glbUrl` returned by `forge-3d` (`forge_free`), `mesh-forge`, or `text-to-avatar`. | Returns the **rigged** `glbUrl` and a three.ws pose-studio link (`https://three.ws/forge?action=rig...`) where the model plays the canonical idle/walk clip library. ### `forge_avatar` — text/image → rigged avatar in one call ($0.45 USDC) Chains the whole pipeline: Granite prompt director → FLUX + TRELLIS/Hunyuan3D mesh → Make-It-Animatable auto-rig, so the model loads straight into the pose studio. | Param | Required | Notes | | --- | --- | --- | | `prompt` | one of prompt/images | A single humanoid character, e.g. `"a friendly cartoon astronaut in a glossy white suit"`. | …

How to install
mdr add nirholas/three.ws/auto-rig@sha256:7168a88577d8fe9eThe line at the top of this page pins the label git:20260811.87b7066, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
