Implementation Reference

• src/tools.ts:160-215 (handler)

  The handler function that performs the actual API call to the YCloud WhatsApp endpoint for wa_inbound_mark and all similar tools. It constructs the URL, sends the axios request, and formats the response or error.
  async (args: Record<string, any>) => { try { // 解析URL中的路径参数 let url = `${apiBaseUrl}${path}`; Object.keys(args).forEach(key => { if (path.includes(`{${key}}`)) { url = url.replace(`{${key}}`, encodeURIComponent(String(args[key]))); delete args[key]; } }); // 提取请求体和查询参数 const { body, ...queryParams } = args as Record<string, any>; // 设置请求选项 const requestOptions: any = { url, method: method.toUpperCase(), headers: { 'Content-Type': 'application/json', ...headers }, params: Object.keys(queryParams).length > 0 ? queryParams : undefined, data: body, }; // 发送请求 const response = await axios(requestOptions); return { content: [{ type: 'text' as const, text: JSON.stringify(response.data, null, 2) }] }; } catch (error: unknown) { if (axios.isAxiosError(error) && error.response) { return { content: [{ type: 'text' as const, text: JSON.stringify({ error: true, status: error.response.status, message: error.response.data?.message || error.message, data: error.response.data }, null, 2) }] }; } return { content: [{ type: 'text' as const, text: JSON.stringify({ error: true, message: error instanceof Error ? error.message : String(error) }, null, 2) }] }; } }
• src/tools.ts:105-108 (registration)

  Specific logic that generates the tool name 'wa_inbound_mark' by extracting the action 'mark' from OpenAPI operationIds containing 'whatsapp_inbound_message-mark'.
  } else if (operationId.includes('whatsapp_inbound_message')) { // 从operationId中提取动作部分 const action = operationId.split('-')[1] || ''; operationId = `wa_inbound_${action}`;
• src/tools.ts:156-219 (registration)

  The dynamic registration of the tool using McpServer.tool(), where toolName will be 'wa_inbound_mark' for the matching OpenAPI operation.
  server.tool( toolName, description, paramsSchema, async (args: Record<string, any>) => { try { // 解析URL中的路径参数 let url = `${apiBaseUrl}${path}`; Object.keys(args).forEach(key => { if (path.includes(`{${key}}`)) { url = url.replace(`{${key}}`, encodeURIComponent(String(args[key]))); delete args[key]; } }); // 提取请求体和查询参数 const { body, ...queryParams } = args as Record<string, any>; // 设置请求选项 const requestOptions: any = { url, method: method.toUpperCase(), headers: { 'Content-Type': 'application/json', ...headers }, params: Object.keys(queryParams).length > 0 ? queryParams : undefined, data: body, }; // 发送请求 const response = await axios(requestOptions); return { content: [{ type: 'text' as const, text: JSON.stringify(response.data, null, 2) }] }; } catch (error: unknown) { if (axios.isAxiosError(error) && error.response) { return { content: [{ type: 'text' as const, text: JSON.stringify({ error: true, status: error.response.status, message: error.response.data?.message || error.message, data: error.response.data }, null, 2) }] }; } return { content: [{ type: 'text' as const, text: JSON.stringify({ error: true, message: error instanceof Error ? error.message : String(error) }, null, 2) }] }; } } ); registeredTools.add(toolName); registeredToolsCount++; }
• src/tools.ts:9-50 (schema)

  Helper function that extracts and creates Zod schemas for tool parameters from the OpenAPI operation's parameters and requestBody.
  function extractParamsSchema(operation: any): any { const properties: Record<string, any> = {}; const required: string[] = []; // 处理路径参数 if (operation.parameters) { operation.parameters.forEach((param: any) => { if (param.in === 'path' || param.in === 'query') { let schema; switch (param.schema?.type) { case 'string': schema = z.string(); break; case 'integer': schema = z.number().int(); break; case 'number': schema = z.number(); break; case 'boolean': schema = z.boolean(); break; default: schema = z.any(); } properties[param.name] = schema; if (param.required) { required.push(param.name); } } }); } // 处理请求体 if (operation.requestBody) { properties['body'] = z.any(); required.push('body'); } return properties; }
