Kobold MCP Server

Instructions

Implementation Reference

• src/index.ts:346-357 (handler)

  Handler logic for POST-based tools like kobold_generate: validates arguments using the tool's schema, then forwards the request via HTTP POST 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:18-28 (schema)

  Zod schema defining the input parameters for the kobold_generate tool, including prompt and various generation options.

  const GenerateSchema = BaseConfigSchema.extend({
      prompt: z.string(),
      max_length: z.number().optional(),
      max_context_length: z.number().optional(),
      temperature: z.number().optional(),
      top_p: z.number().optional(),
      top_k: z.number().optional(),
      repetition_penalty: z.number().optional(),
      stop_sequence: z.array(z.string()).optional(),
      seed: z.number().optional(),
  });

• src/index.ts:177-181 (registration)

  Tool registration in the listTools response, specifying name, description, and input schema.

  {
      name: "kobold_generate",
      description: "Generate text with KoboldAI",
      inputSchema: zodToJsonSchema(GenerateSchema),
  },

• src/index.ts:332-332 (registration)

  Endpoint mapping for kobold_generate in the POST dispatch table, linking tool name to API path and schema.

  kobold_generate: { endpoint: '/api/v1/generate', schema: GenerateSchema },

• src/index.ts:146-162 (helper)

  Helper function that performs HTTP requests to the KoboldAI API, used by the tool handlers.

  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();
  }
