12 tools

• search_assets

  Search the Polyfork catalogue of low-poly 3D assets for three.js. Use this whenever the user needs a model for a scene, game or site. Filter by triangle budget when the target is mobile or performance-sensitive. Results mix FREE and PRO assets: each carries `free` and `plan`…

• get_asset

  Full detail for one asset: real-world size in metres, triangle count, palette, animatable parts, renders you can open to SEE it, and the correct download URLs for the caller. A model with has_ik true also returns a measured `gait` or `arm` block: segment lengths, foot offsets…

• find_matching

  Given one asset, return assets that BELONG IN A SCENE WITH IT: same kit first, then shared palette, then compatible real-world scale, spread across classes so you get a house, a tree and a barrel rather than eight houses. Use this to turn a single pick into a scene. Returns a…

• get_variant

  Turn a plain-words request ("oak cask", "taller", "five sails") into a ready call. `want` is matched against this asset's KNOB NAMES and OPTION VALUES, not against colour vocabulary: use the words from its -params.json into a ready createAsset() call for a remixable asset, plus…

• preview_scene

  Compose assets into a scene and return a URL the user can OPEN and orbit. Use it instead of handing over a block of three.js the user cannot run. Works with paid assets too: they render from a public preview, so the scene looks finished whether or not the user owns them. The…

• list_kits

  Kits are coherent sets built to one palette and one grid. Reach for a kit when the user is building a whole environment rather than looking for one object. Each carries a status: "published" means every planned part is built, "filling-up" means parts are still landing — and the…

• get_kit

  Every published part of one kit, with the same detail get_asset gives, so you can compose a whole scene from one call. Works on a kit that is still FILLING UP: you get the parts that exist today. NO kit is sold as a bundle, at any status, so recommend its parts rather than the…

• get_terrain

  AT WHAT HEIGHT DO I PLACE THIS, and where can I build. Every kit ships a procedural TERRAIN program for its own ground, and the ground is no longer flat, so a y of 0 is wrong almost everywhere. Pass `at` with the x/z you want to place at and you get the ground height there; set…

• who_am_i

  What this connection can currently do: whether a key is attached, which assets and kits it owns, and therefore which downloads will work. Call it before promising the user a paid file, and when a download 404s, rather than guessing whether the problem is the key or the asset.

• buy_plan

  Buy a Polyfork plan: Pro (monthly or yearly) or a one-payment lifetime seat. This tool NEVER charges anything itself. It returns a Stripe Checkout link and the exact amount; the payment happens on that page (cards and Link), and only with the user's approval of the amount. Call…

• get_help

  How to use this server: what the metadata means, the rules that are easy to get wrong (real-world metres, one material, never rescale to fake a fit), and worked recipes for building a scene. Call it when a tool did not behave as you expected, or before a multi-step build…

• report_need

  Report a gap. Four kinds, and the last three are about THIS SERVER rather than the catalogue: kind=asset, we do not model what the user asked for (offer this whenever a search is empty or thin); kind=capability, you needed the server to do something it cannot; kind=output, a…
