Set up reusable style presets in the SD WebUI so the MCP server can reference them by name.

Why

Currently every generation requires crafting a full prompt from scratch. Saved styles allow consistent results with minimal input — e.g. the MCP server could accept style: "architectural-maquette" and automatically prepend the right prompt tokens and negative prompt.

Steps

Create styles.csv entries for key styles:
- architectural-maquette — white model, green trees, clean geometric buildings
- isometric-game — colorful isometric citybuilder aesthetic
- concept-art — cinematic game key art style
Each style should define both positive and negative prompt additions
Update the MCP server on alcatraz to expose a list_styles tool and accept a style parameter in generate_image

Set up reusable style presets in the SD WebUI so the MCP server can reference them by name. ## Why Currently every generation requires crafting a full prompt from scratch. Saved styles allow consistent results with minimal input — e.g. the MCP server could accept `style: "architectural-maquette"` and automatically prepend the right prompt tokens and negative prompt. ## Steps 1. Create `styles.csv` entries for key styles: - `architectural-maquette` — white model, green trees, clean geometric buildings - `isometric-game` — colorful isometric citybuilder aesthetic - `concept-art` — cinematic game key art style 2. Each style should define both positive and negative prompt additions 3. Update the MCP server on alcatraz to expose a `list_styles` tool and accept a `style` parameter in `generate_image`

Update from caymans session

\ has been created on caymans with three presets:

Style name	Description
\	White scale model / diorama with green trees, tilt-shift, studio lighting
\	Colorful city builder game art, low-poly, clean vector style
\	Cinematic game key art, dramatic lighting, matte painting

All styles use \ placeholder so the user prompt gets inserted into the template. Each has a matching negative prompt.

The file is gitignored (upstream .gitignore excludes /styles.csv), so it lives only on disk at C:/AI/stable-diffusion-webui/styles.csv.

Remaining work (alcatraz side)

Update /srv/services/sd-mcp/index.js to add a \ tool that queries - [ ] Add a \ parameter to the \ tool that passes the style name in the API request
The WebUI API accepts styles via the \ array field in txt2img/img2img requests

MCP server updated on alcatraz to support style and lora parameters in generate_image, plus new list_styles and list_loras tools.

Styles are defined in the SD WebUI styles.csv and can be referenced by name. LoRAs are referenced by filename and appended as <lora:name:weight> to the prompt.

Test with architectural-maquette style confirmed working.
