Kobold MCP Server

Implementation Reference

• src/index.ts:307-324 (handler)

  Handler for kobold_sd_models and other GET tools: maps to '/sdapi/v1/sd-models' endpoint and proxies the request via makeRequest, returning the JSON response.

  const getEndpoints: Record<string, string> = {
      kobold_max_context_length: '/api/v1/config/max_context_length',
      kobold_max_length: '/api/v1/config/max_length',
      kobold_generate_check: '/api/extra/generate/check',
      kobold_model_info: '/api/v1/model',
      kobold_version: '/api/v1/info/version',
      kobold_perf_info: '/api/extra/perf',
      kobold_sd_models: '/sdapi/v1/sd-models',
      kobold_sd_samplers: '/sdapi/v1/samplers',
  };
  
  if (getEndpoints[name]) {
      const result = await makeRequest(`${apiUrl}${getEndpoints[name]}`);
      return {
          content: [{ type: "text", text: JSON.stringify(result, null, 2) }],
          isError: false,
      };
  }

• src/index.ts:235-238 (registration)

  Tool registration in ListTools response, specifying name, description, and inputSchema.

      name: "kobold_sd_models",
      description: "List available Stable Diffusion models",
      inputSchema: zodToJsonSchema(SDModelsSchema),
  },

• src/index.ts:97-97 (schema)

  Input schema for kobold_sd_models tool, equivalent to BaseConfigSchema (optional apiUrl).

  const SDModelsSchema = BaseConfigSchema;

• src/index.ts:11-13 (schema)

  BaseConfigSchema used by SDModelsSchema and all tools, allowing optional apiUrl override.

  const BaseConfigSchema = z.object({
      apiUrl: z.string().default('http://localhost:5001'),
  });

• src/index.ts:146-162 (helper)

  Shared helper function makeRequest used to proxy all API calls, including for kobold_sd_models.

  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();
  }
