Implementation Reference
- mcp-server/src/server.ts:531-548 (handler)Handler for generate_icon tool: constructs a specialized prompt using buildIconPrompt and calls the shared image generator.
case "generate_icon": { const prompt = this.buildIconPrompt(args); const imageRequest: ImageGenerationRequest = { prompt, outputCount: Array.isArray(args?.sizes) && args?.sizes.length > 0 ? args.sizes.length : 1, mode: "generate", preview: args?.preview as boolean, noPreview: (args?.noPreview as boolean) || (args?.["no-preview"] as boolean), }; response = await this.imageGenerator.generateTextToImage(imageRequest); break; } - mcp-server/src/types.ts:47-53 (schema)TypeScript interface defining the arguments for the generate_icon tool.
export interface IconPromptArgs { prompt?: string; type?: string; style?: string; background?: string; corners?: string; } - mcp-server/src/server.ts:222-279 (registration)Registration of the generate_icon tool in the list of available tools, including detailed input schema.
