MCP SERVERGenerate an image and then keep working on it — background cut out or relit, canvas extended, an object swapped or recoloured, resolution raised — in one conversation.
LABSCO SUMMARY
Every editing tool takes an imageFileUri and writes a new named file, so a generated image feeds background removal, then outpainting, then an upscale, with no round trip through a desktop editor. stability-ai-0-list-resources exists for the moment the chain gets long enough that the assistant has lost track of what it already produced.
A Stability AI client covering generation and the editing passes that follow it. Images are addressed by file URI, and a listing tool returns the ones already available so an earlier output becomes the next input.
A Stability AI account with its API key in STABILITY_AI_API_KEY, and npx on your PATH.

USE CASES
Cut the subject out of its background, put it against one that matches the lighting you want, and raise the resolution — three calls against the same image URI rather than a round trip through an editor.
The sketch drives the composition and the prompt fills in the rendering, with control strength deciding how closely the result holds to what you drew.
Both edits are described rather than masked: name what to find and what it should become, and the rest of the frame is left as it was.
Outpainting extends the canvas in whichever directions you need rather than cropping the subject, so a square asset becomes a banner without losing what was at the edges.
One approved image becomes the style reference for everything that follows, and the resource listing is how the assistant finds the earlier outputs to reference rather than asking you for paths.
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
stability-ai-0-list-resourcesUse this to check for files before deciding you don't have access to a file or image or resource. It pulls in a list of all of user's available Resources (i.e. image files and their URI's) so we can reference pre-existing images to manipulate or upload to Stability AI.
stability-ai-control-sketchTranslate hand-drawn sketches to production-grade images.
stability-ai-control-structureGenerate a new image while maintaining the structure of a reference image
stability-ai-control-styleGenerate a new image in the style of a reference image
stability-ai-generate-imageGenerate an image of anything based on a provided prompt.
stability-ai-generate-image-sd35Generate an image using Stable Diffusion 3.5 models with advanced configuration options.
stability-ai-outpaintExtends an image in any direction while maintaining visual consistency.
stability-ai-remove-backgroundRemove the background from an image.
stability-ai-replace-background-and-relightReplace background and adjust lighting of an image
stability-ai-search-and-recolorSearch and recolor object(s) in an image
stability-ai-search-and-replaceReplace objects or elements in an image by describing what to replace and what to replace it with.
stability-ai-upscale-creativeEnhance image resolution up to 4K using AI with creative interpretation. This tool works best on highly degraded images and performs heavy reimagining. In general, don't use this (expensive) tool unless specifically asked to do so, usually after trying stability-ai-upscale-fast first.
stability-ai-upscale-fastCheap and fast tool to enhance image resolution by 4x.
BEFORE YOU INSTALL
13 tools when we connected. Every tool is registered with a stability-ai- prefix, so bare names from the documentation will not resolve. inpaint is on the roadmap, not available. Each call costs Stability credits, from $0.01 to $0.25.
CONTEXT COST
Rated by the size of the 13 tool definitions that ride along on every turn, not by how many there are
