Implementation Reference
- src/mcp.ts:15-36 (handler)Core handler function that proxies the tool call to the remote API at https://mcp.xiaobenyang.com/api, passing toolName 'get_brent_rub_rate' and arguments, and formats the response as MCP text content.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 }] }; };
- src/mcp.ts:39-48 (helper)Helper function that prepares arguments by adding toolName and calls the core proxy handler.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:50-65 (registration)Registers a tool on the MCP server with the given name, description, input schema, and the shared handler passing the name.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:90-132 (registration)Dynamically registers all tools (including get_brent_rub_rate) by fetching the tool list from https://mcp.xiaobenyang.com/getMcpDesc?mcpId=1777316659852291, parsing JSON schemas to Zod, and calling addToolXiaoBenYangApi for each.for (const apiDesc of apiDescList) { let inputSchema = JSON.parse(apiDesc.inputSchema); 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(); } }); addToolXiaoBenYangApi( apiDesc.name, apiDesc.description ? apiDesc.description : apiDesc.name, zodDict); }
- src/mcp.ts:94-125 (schema)Builds Zod input schema dynamically from the remote tool's JSON schema properties and required fields.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(); } });
