3D Valley MCP

An official MCP server operated by 3D Valley that enables AI agents to search and download over 10,000 CC0 3D models, PBR textures, and HDRIs. It supports generating 3D models from images or text, retexturing and remeshing existing assets, and creating seamless PBR textures, all authenticated via OAuth with a free account.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

3D Valley: free CC0 3D models, PBR textures and HDRIs, and paid 3D generation. - Look in the free library first (search_assets); every model is a GLB in metres, +Y up, origin at the base. Check size_m before placing. - When nothing fits, generate_model makes one object from a picture or words, for credits the user bought. For game or web use pass max_faces (e.g. 10000), and style lowpoly when the scene uses low-poly assets. account shows the balance and every price; state the price before spending, and pass max_credits. - Long jobs return job_id: call get_job until it is done. Repeating a call never charges twice. - Files on the user's machine go up with upload_file (it returns a curl command). - Library assets are CC0 and need no credit, but when you write credits, a README, a store page or an about screen for a project that uses them, include each asset's credit line (get_asset returns it as credit and credit_html). It credits the maker and helps others find the library.

search_assets — Search free CC0 3D assets

Advertised by the server during the last successful anonymous check.

Advertised read-only

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.

Advertised by the server during the last successful anonymous check.

Advertised read-only

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.

generate_model — Generate a 3D model

Advertised by the server during the last successful anonymous check.

Open-world

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.

edit_model — Edit a 3D model

Advertised by the server during the last successful anonymous check.

Open-world

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 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.

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start 3d-valley-mcp and inspect its tools.

VS Code configuration

{
  "servers": {
    "3d-valley-mcp": {
      "type": "http",
      "url": "https://3dvalley.com/mcp"
    }
  }

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http 3d-valley-mcp https://3dvalley.com/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Claude Desktop configuration

https://3dvalley.com/mcp

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.

Windsurf configuration

{
  "mcpServers": {
    "3d-valley-mcp": {
      "serverUrl": "https://3dvalley.com/mcp"
    }
  }
}
