3dCMS MCP server

• Registry nameinfo.3dcms/mcpverified in the MCP registry

The registry name sits under 3dcms.info. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-10-24 the server answered initialize and tools/list without a sign-in. First answer in 101 ms.

• Its tools do publish a crawlable 3D site at its own URL, but not generate 3D models and materials from text prompts.
• Checked on 3 of the 7 days it takes to judge reliability.

Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (30%), doing the product's job (25%), definitions (20%), context (10%) and use (15%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →

• list_scenes

  Use this first when the user mentions their 3dCMS scenes, a site they built with 3dCMS, or wants to edit, publish or check something they made. Lists the 3D scenes saved in their 3dCMS account (editable "sources"), newest first, 40 at a…

• probe_lighting

  For one world point, the contribution of EVERY light in the scene, computed from the saved scene (no render, instant): each light node in reach with its value (three's falloff and spot cone, from the node's WORLD position and aim), the…

• probe_framing

  Read a saved camera (cameraId), or an exact pose, as a visitor sees it at the screen shapes they actually have (16:9 desktop and 9:16 phone by default), against the rules a photographer and a web designer use. A PAGE shot (a page's own…

• design_review

  A designer's critique of a scene (or one page with pageId) against its BRIEF: what it is for (settings.design, or, when none is declared, what it reads as and why), its palette (dominant, secondary, accent, harmony, temperature, key, and…

• upload_asset

  Put a file into the account's asset library and get back its /assets url to use in apply_ops (a glb on a geometry node as data {primitive:"imported", assetUrl}, an image in materialMaps or a webImage src, an mp3 in an audioClip…

• compose_surface

  Make a flat surface that looks PRINTED ON a real material: a quote on a stretched canvas, a poster, a shop sign, a label, a plaque, a book cover. Start from a `base`: a texture set from the library (`setId` from list_assets; tiled at…

• measure

  Measure nodes in a saved scene (analytic, instant, no render). For each node in nodeIds: its world centre, its size along its own axes after every scale above it, its world bounding box, and `clearance`: the nearest visible thing in each…

• get_scene

  Read a compact, high-signal summary of one scene: its nodes (id, type, name, parent, position, rotation [euler radians], scale, primitive, real `size` under the keys `data` takes (width/height/depth, radius, height, tube: write it back as…

• create_scene

  Use this when the user wants a 3D website, a walkable portfolio, a product showcase, a gallery, an exhibit, an event page or any interactive space they can share as a link. Creates the scene in their 3dCMS account and returns its id; then…

• apply_ops

  Use this to build or change a 3D scene: add rooms, text, pictures, links, models, lights, pages. Edit a scene by applying a batch of operations ATOMICALLY (all-or-nothing). Call this for any add / move / edit / delete / duplicate / group…

• list_assets

  Search the images, models and sounds in the account AND the shared public library (frames, props, texture sets; `scope` mine|shared|all, default all). A row with shared:true is copied in first with upload_asset {assetId}: place the url…

• get_scene_screenshot

  Render the scene server-side (real WebGL, headless) and return screenshot image(s) — your EYES on the scene. Use it after apply_ops batches and after probe_framing, and judge each image as a photographer and a web designer would: one…

• publish_scene

  Use this when the user wants their scene live as a public link to share, or to update one already live. Publish a saved scene to a PUBLIC, shareable URL so anyone can view it in 3D in a browser — no login required. PUBLISHING IS PARTLY…
