Turn a natural-language prompt into a textured, downloadable GLB model on the free three.ws text→3D lane (NVIDIA NIM / Microsoft TRELLIS). No API key and no account — the platform's server-side keys cover provider cost.
The result is always two things: a durable glbUrl (download / import into any 3D tool) and a viewer link that renders the model in the browser.
| Goal | Use |
|---|---|
| A single object / prop / creature from text | this skill (free lane) |
| A posable humanoid character with a skeleton | create-3d-avatar |
| Add a skeleton to a GLB you already have | rig-a-model |
If the three.ws MCP server is connected, call the free tool directly:
forge_free{ "prompt": "<description>", "tier": "draft" }- prompt — 3–1000 chars. Lead with the subject, then its key materials and colors. The free lane conditions on ~77 characters, so front-load what matters: "a friendly round robot mascot, glossy white plastic, big blue eyes". - tier — draft (fast, default), standard, or high. All free; higher tiers only take longer.
glbUrl, viewerUrl, tier, backend, durationMs.This is text-only (the free TRELLIS preview does not accept uploaded photos). For image / multi-view → 3D, use the art-directed lanes described in [reference.md](reference.md).
No MCP client required. The same free lane is a public JSON-RPC endpoint at https://three.ws/api/mcp-studio (no auth, no account):
curl -s -X POST https://three.ws/api/mcp-studio \
-H 'content-type: application/json' \
-d '{

glbUrl for download / import into Blender, Unity, three.js, etc.glbUrl into the rig-a-model skill.The full three.ws MCP server also exposes art-directed and image→3D lanes (mesh_forge) and paid lanes with denser geometry. Those, the tier trade-offs, the raw POST /api/forge REST shape, and full error handling are in [reference.md](reference.md) — load it only when you need more than the free text→3D path above.
The free lane is shared and protected by per-IP rate limits and a global capacity breaker. Handle these and retry rather than failing:
rate_limited / busy — honor retryAfter (seconds) and try again.not_configured — the durable lane is momentarily cold; retry shortly.lane_degraded — a result was produced but its URL was unreachable; retry.Never report a dead or empty link as success — only return a glbUrl the call actually produced.
