Kobold MCP Server

Implementation Reference

• src/index.ts:346-357 (handler)

  Shared handler logic for all POST-endpoint tools like kobold_token_count: validates arguments using the tool's schema, proxies the request to the 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:46-48 (schema)

  Zod input schema for the kobold_token_count tool: optional apiUrl and required text string for token counting.

  const TokenCountSchema = BaseConfigSchema.extend({
      text: z.string(),
  });

• src/index.ts:198-202 (registration)

  Registration of kobold_token_count in the ListTools response, providing name, description, and input schema.

  {
      name: "kobold_token_count",
      description: "Count tokens in text",
      inputSchema: zodToJsonSchema(TokenCountSchema),
  },

• src/index.ts:333-333 (registration)

  Mapping of kobold_token_count to its KoboldAI API endpoint and schema in the tool dispatch handler.

  kobold_token_count: { endpoint: '/api/extra/tokencount', schema: TokenCountSchema },

• src/index.ts:146-162 (helper)

  Helper function used by all tool handlers to make HTTP requests to the KoboldAI backend API.

  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();
  }
