fake-upstream/src/catalogue.ts ports infra/fake-storyteller-web's catalogue: the real model ids, creators and display names for image, video, audio, mesh and splat, with one representative capability profile per kind. The image and video endpoints' own `provider` filter (OmniGen*ModelsProvider: "artcraft" — the default — or "all") is mirrored, including a 400 for other values; audio, mesh and splat declare no filter and list everything. All five catalogues validate against the spec. src/mcp/tools/list-models.ts always asks upstream for "all" so the catalogue is complete, applies the caller's GenerationProvider filter client-side via the providers block, and passes each model's capability fields through verbatim — what lets a client build a valid estimate_cost call from one source of truth. Typecheck caught the contract mismatch on the way: the tool first sent GenerationProvider values as the endpoint's query, which the fake accepted and production would reject; the generated types refused it. Tests (5 tool + 8 fake): normalisation and pass-through, "all" query for image/video, client-side provider filtering for every kind, every kind served; spec-valid catalogues, upstream's default and enum, no-filter kinds listing everything. Server and handler suites list the tool under read:catalog. Claude-Session: https://claude.ai/code/session_01H3gfN2NCx3hBXSrZXYHUQ3
The IDE for artists.
ArtCraft
ArtCraft is the IDE for interactive AI image and video creation. We turn prompting into crafting, so your ideas become a form of tangible expression and computing. This is Adobe Photoshop for everyone, and we're giving away the source code!
Show, Don't Tell: Advanced Crafting Features
Text-to-image is great, but artists need control. It's important to know what your image will look like before you generate it, and it's vitally important to achieve consistency and repeatability.
Note: all of the above videos were generated for free with Grok Video; the cost to build this README was negligible.
Quick and Easy Prompting
We haven't abandoned text-to-asset generation for quick prototyping and ideation. We support every popular workflow in a first class fashion.
