Implementation Reference

• src/mcp.ts:39-48 (handler)

  Shared handler function for all dynamically registered tools, including "get_user_info". It receives arguments and toolName, merges them, and delegates to the API proxy helper. Note: Has a misleading error message referencing 'aid' instead of toolName.

  const handleXiaoBenYangApi = async (args: Record<string, any>, toolName: string) => {
      // 校验aid是否存在
      if (toolName === undefined || toolName === null) {
          throw new Error("缺少必要参数 'aid'");
      }
      // 合并参数
      const fullArgs = {...args, toolName: toolName};
      // 调用API
      return calcXiaoBenYangApi(fullArgs);
  };

• src/mcp.ts:92-126 (schema)

  Dynamically constructs Zod input schema for each tool based on remote JSON schema description (parsed at line 91). Maps JSON types to Zod types and handles required/optional fields. Used for all tools including "get_user_info".

  const zodDict: Record<string, z.ZodTypeAny> = {};
  
  Object.entries(inputSchema.properties).forEach(([name, propConfig]) => {
      let zodType;
      let pt = (propConfig as { type: string }).type;
      switch (pt) {
          case 'string':
              zodType = z.string();
              break;
          case 'number':
              zodType = z.number();
              break;
          case 'boolean':
              zodType = z.boolean();
              break;
          case 'integer':
              zodType = z.int32();
              break;
          case 'array':
              zodType = z.array(z.any());
              break;
          case 'object':
              zodType = z.object(z.any());
              break;
          default:
              zodType = z.any();
      }
  
      if (inputSchema.required?.includes(name)) {
          zodDict[name] = zodType;
      } else {
          zodDict[name] = zodType.optional();
      }
  });

• src/mcp.ts:50-65 (registration)

  Registers a tool on the MCP server with given name (e.g., "get_user_info"), description, Zod inputSchema, and a closure over the shared handler passing the tool name. Called dynamically for each remote tool description.

  const addToolXiaoBenYangApi = function (
      name: string,
      desc: string,
      params: Record<string, ZodType>
  ) {
      server.registerTool(
          name,
          {
              title: name,
              description: desc,
              inputSchema: params,
          }
          ,
          async (args: Record<string, any>) => handleXiaoBenYangApi(args, name)
      )
  };

• src/mcp.ts:15-36 (helper)

  Core helper that proxies the tool execution to the remote service at https://mcp.xiaobenyang.com/api, sending toolName as 'func', API key, MCP ID, and arguments as form data. Formats response as MCP content block.

  const calcXiaoBenYangApi = async function (fullArgs: Record<string, any>) {
      // 发起 POST 请求
      let response = await fetch('https://mcp.xiaobenyang.com/api', {
          method: 'POST',
          headers: {
              'XBY-APIKEY': apiKey,
              'func': fullArgs.toolName,
              'mcpid': mcpID
          },
          body: new URLSearchParams(fullArgs)
      });
      const apiResult = await response.text();
  
      return {
          content: [
              {
                  type: "text",
                  text: apiResult // 将字符串结果放入 content 中
              }
          ]
      } as { [x: string]: unknown; content: [{ type: "text"; text: string }] };
  };
