Implementation Reference
- src/index.ts:346-357 (handler)Shared handler logic for all POST-based tools like kobold_img2img: validates arguments with the tool's schema, proxies the request to the specified KoboldAI API endpoint, and returns the JSON response.if (postEndpoints[name]) { const { endpoint, schema } = postEndpoints[name]; const parsed = schema.safeParse(args); if (!parsed.success) { throw new Error(`Invalid arguments: ${parsed.error}`); } const result = await makeRequest(`${apiUrl}${endpoint}`, 'POST', requestData); return { content: [{ type: "text", text: JSON.stringify(result, null, 2) }], isError: false, };
- src/index.ts:77-91 (schema)Zod schemas defining the input parameters for kobold_img2img (Img2ImgSchema extends Txt2ImgSchema, which extends BaseConfigSchema).const Txt2ImgSchema = BaseConfigSchema.extend({ prompt: z.string(), negative_prompt: z.string().optional(), width: z.number().optional(), height: z.number().optional(), steps: z.number().optional(), cfg_scale: z.number().optional(), sampler_name: z.string().optional(), seed: z.number().optional(), }); const Img2ImgSchema = Txt2ImgSchema.extend({ init_images: z.array(z.string()), denoising_strength: z.number().optional(), });
- src/index.ts:250-252 (registration)Registration of the kobold_img2img tool in the ListTools response, including its name, description, and input schema.name: "kobold_img2img", description: "Transform existing image using prompt", inputSchema: zodToJsonSchema(Img2ImgSchema),
- src/index.ts:341-341 (registration)Internal registration of the kobold_img2img tool's endpoint and schema in the postEndpoints routing map used by the handler.kobold_img2img: { endpoint: '/sdapi/v1/img2img', schema: Img2ImgSchema },
- src/index.ts:146-162 (helper)Helper function for making HTTP requests to the KoboldAI API, used by the tool handler.async function makeRequest(url: string, method = 'GET', body: Record<string, unknown> | null = null) { const options: RequestInit = { method, headers: body ? { 'Content-Type': 'application/json' } : undefined, }; if (body && method !== 'GET') { options.body = JSON.stringify(body); } const response = await fetch(url, options); if (!response.ok) { throw new Error(`KoboldAI API error: ${response.statusText}`); } return response.json(); }
