Tanish Manku 0ec3d93437 mcp: prove the guardrails fire, test the misconfigured entry path, single-target fake config
Whole-pass audit of the scaffold found three gaps and closes them:

- Guardrail tests only ever passed. The wrangler.toml mapping and the
  MCP_ENVIRONMENT isolation checks are now pure functions
  (test/helpers/) tested against mutated input: preview→production,
  production→fake, local→production, mislabelled env, shared KV id,
  extra "staging" env, changed entry point, a file reading the binding,
  a file branching on the environment name.
- src/index.ts's misconfiguration path had no test. Added: 500 with the
  exact mismatch message, memoized failure across requests, missing
  bindings reported, sound bindings still serve.
- fake-upstream had an [env.preview] block it did not need (one deploy
  target) which made wrangler warn; now top-level only, script `deploy`.

Also verified out-of-band and recorded in CLAUDE.md as rules 4–6 of the
working method: `pnpm install --frozen-lockfile`, `wrangler deploy
--dry-run` for both Workers (production bundle contains no fake code),
the eslint boundary rejects a server→fake import, and both Workers boot
under `wrangler dev` and answer over HTTP.

pnpm check: typecheck, eslint, prettier, 37 tests passing.

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.

Feature Demo + Explanation
Image to Location Video Placing virtual actors into physical environments establishes single-location consistency. You can film multiple shots within a room without having things disappear.
3D Image Compositing Video Use images (backdrops, foreground elements, props, etc.) in scenes with depth and blend them naturally together. Just a couple of images usually leads to great compositions.
2D Image Compositing Video Use images, background removal, layers, and simple drawing tools to precisely compose a scene.
Image to 3D Mesh Video It's almost impossible to lay out complicated objects or block complicated scenes; turning images into 3D helps position elements exactingly and intentionally.
Character Posing Video You can dynamically pose your characters to achieve the precise character, scene, and camera blocking before calling "action".
Scene Blocking w/ Kit Bashing Video Use 3D asset kits to precisely block out your scene: get the correct angles, object positions, and rich depth layering you can't with text prompting.
Character Identity Transfer Video Use mannequins as simple 3D ControlNets for posing any character.
Background Removal Video Remove backgrounds from images to make them useful in 2D or 3D compositing. They can be props, layers, or backdrops.
Mixed Asset Crafting Video You can use image cutouts, worlds, and simple 3D meshes all together to precisely and intentionally lay out your scenes.

Canvas Editing (preview coming soon)
Scene Relighting (preview coming soon)

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.

Feature Demo + Explanation
Text to Image Video Text prompt over a dozen different image models.
Image Editing Video Edit with Nano Banana Pro and GPT Image 1.5.
Image Editing Video Use inpainting, drawing, masking, etc. to edit images.
Image to Video Video Image to video with lots of different options and controls.
Image Inpainting (preview coming soon)
Image Ingredients (preview coming soon)
