Implementation Reference

• src/index.ts:306-335 (handler)

  Complete implementation of the get_price tool handler, including registration via server.tool(), Zod schema definition (symbol and symbols parameters), and the async handler function that calls Binance API /api/v3/ticker/price endpoint

  server.tool(
      "get_price",
      {
          symbol: z.string().optional().describe("Trading pair symbol, e.g. BTCUSDT"),
          symbols: z.array(z.string()).optional().describe("Array of multiple trading pair symbols")
      },
      async (args: { symbol?: string; symbols?: string[] }) => {
          try {
              let params = {};
              if (args.symbol) {
                  params = { symbol: args.symbol };
              } else if (args.symbols) {
                  params = { symbols: JSON.stringify(args.symbols) };
              }
  
              const response = await axios.get(`${BASE_URL}/api/v3/ticker/price`, {
                  params,
                  ...getProxyConfig(),
              });
              return {
                  content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
              };
          } catch (error: any) {
              return {
                  content: [{ type: "text", text: `Failed to get price ticker: ${error.message}` }],
                  isError: true
              };
          }
      }
  );

• src/index.ts:308-311 (schema)

  Zod schema definition for get_price tool parameters - validates optional 'symbol' (single trading pair) or 'symbols' (array of multiple trading pairs) input parameters

  {
      symbol: z.string().optional().describe("Trading pair symbol, e.g. BTCUSDT"),
      symbols: z.array(z.string()).optional().describe("Array of multiple trading pair symbols")
  },

• src/index.ts:406-433 (helper)

  Helper function getProxyConfig() used by the get_price handler to configure HTTP/SOCKS5 proxy settings for API requests based on environment variables

  function getProxyConfig(): any {
      // 优先使用SOCKS5代理
      if (socksProxyURL) {
          try {
              const agent = new SocksProxyAgent(socksProxyURL);
              return { httpsAgent: agent, httpAgent: agent };
          } catch (error) {
              console.error(`Failed to create SOCKS proxy agent: ${error}`);
          }
      }
      
      // 回退到HTTP代理
      if (httpProxyURL) {
          try {
              const urlInfo = new URL(httpProxyURL);
              return {
                  proxy: {
                      host: urlInfo.hostname,
                      port: parseInt(urlInfo.port) || (urlInfo.protocol === 'https:' ? 443 : 80),
                      protocol: urlInfo.protocol.replace(":", "")
                  }
              };
          } catch (error) {
              console.error(`Failed to parse HTTP proxy URL: ${error}`);
          }
      }
      
      return {};
