3D Valley MCP Server

Make one 3D object (never a scene) as a textured GLB, from a picture (image) or a description (prompt). Costs credits, which the user bought: image models trellis-2 5, trellis-2-pro 15, hunyuan-3d-3-1-pro 90, tripo-3-1 50, tripo-3-1-detailed 100; from a prompt add the picture model (flux-2-klein 1). Pass max_credits to refuse anything dearer. For a game or the web pass max_faces (5000-20000; the default is 200,000 triangles), and from a prompt style lowpoly to match low-poly kits. The GLB stands on its base at the origin, like library models. Waits about 45 s, then returns job_id for get_job if it is not done. Calling again with the same arguments resumes the same job and never charges twice; pass a new idempotency_key to make another one.

A seamless PBR texture set (base colour, normal, height, roughness, metallic at 2048 px) from a description, for flux-2-klein-material 2, muse-image-material 5, gpt-image-2-5-material 8 credits.

The credit balance, the price of every tool and model in credits (1 credit = $0.01), the rate limits and this key's daily spending cap. Check before spending.

Full details for one library asset: download URLs per format and resolution, size in metres, up axis and origin, texture maps, a credit line (credit, credit_html), related assets, and import notes for Godot, Unity, three.js and Blender. When you write credits or a README for a project using the asset, include its credit line. Read-only, free.

Search the free CC0 library of 3D models, PBR textures and HDRIs by meaning and filters. Every model is a GLB measured in metres, +Y up, origin at the base. Check size_m before placing an asset; use min_size_m >= 2 for floors and walls. previews (max 6) attaches thumbnails, which is cheaper than downloading the wrong asset. Each result has match (strong, good or weak); when none is better than weak the answer says so, and generate_model is the way to get the object. Read-only, free with a free account.

Change a model you have: retexture (new PBR textures from a picture or words; trellis-2-texture 5, trellis-2-texture-pro 10, tripo-texture 20, tripo-texture-detailed 40, meshy-texture 50 credits) or remesh (new, clean topology at a face count; tripo-remesh 50 credits). The mesh is an https URL, an upload id from upload_file, a library id (ph:wooden_barrel_01) or a job id, so steps chain without downloading. Waits about 45 s, then returns job_id for get_job. To reduce, compress, convert or repair a file, use gltf-transform or Blender locally.

Waits up to about 45 s for a job to finish, or reads where it stands. Safe to call again and again; never charges. When done: download URLs for every file, a preview picture, the model's size in metres and triangle count, and an asset id usable as input to the next step.

Give a humanoid character a skeleton and skin weights, as a GLB ready to pose and animate (tripo-rig 45, meshy-rig 35 credits). Humanoids only: two arms, two legs, standing. tripo-rig (default) takes bone_names (mixamo, unity, unreal, vrm) so the engine's own animations play on it; animations adds up to 5 of Tripo's presets in the same job (17 credits each), all in the GLB. meshy-rig returns an FBX, a walk and a run as well. Best on one closed model standing in a T-pose or A-pose; remesh a generated model first, never after. The mesh is a URL, an upload id, a library id or a job id. Waits about 45 s, then returns job_id for get_job.

The server cannot read the user's disk. This returns an upload id and the exact curl command that sends a local file (a mesh or picture) to it; run that command, then pass the id as the image or mesh of another tool. Uploads last 24 hours.
