Tanish Manku 0798f89312 mcp: the protected route — principal from props, stateless Streamable HTTP, revoke on dead session
src/mcp/handler.ts replaces the 501 stub. The provider's decrypted grant
props become a Principal (a grant this build cannot read → 403, never
guessed at); a read-use upstream client is bound to its credential; a
fresh McpServer and the SDK's web-standard Streamable HTTP transport
(stateless, JSON responses) serve the request; and when a tool reports
the upstream no longer accepts the credential, the grant is revoked via
unwrapToken + revokeGrant after the response, so the client's next
request meets a 401 and re-authorizes.

Only /mcp is protected: access tokens are audience-bound to it, so a
legacy /sse route could never be reached with one; the unprotected app
now answers /sse with a 405 pointing at /mcp.

Tests (6, the SDK's real Client + StreamableHTTPClientTransport routed
into worker.fetch, fake upstream in-process): initialize → list →
get_credit_balance with the seeded balances; empty list for a grant
without read:account; 401 unauthenticated; 403 for a grant with
unreadable props; revocation after the fake session is logged out (tool
error, then 401); /sse pointer. Earlier suites that asserted the stub
now assert a JSON-RPC initialize succeeds, with grant props recorded
the way consent records them.

pnpm check: typecheck, eslint, prettier, 181 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.

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)
