Implementation Reference

• src/index.ts:244-266 (handler)

  The main handler function that executes the get_24hr_ticker tool. It accepts optional 'symbol' or 'symbols' parameters, constructs the appropriate request parameters, makes an HTTP GET request to Binance's /api/v3/ticker/24hr endpoint with proxy support, and returns the 24hr price statistics as formatted JSON or an error message.

  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/24hr`, {
              params,
              ...getProxyConfig(),
          });
          return {
              content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
          };
      } catch (error: any) {
          return {
              content: [{ type: "text", text: `Failed to get 24hr price statistics: ${error.message}` }],
              isError: true
          };
      }
  }

• src/index.ts:240-243 (schema)

  Zod schema definition for the get_24hr_ticker tool input parameters. Defines two optional parameters: 'symbol' for a single trading pair (e.g., BTCUSDT) and 'symbols' for an array of multiple trading pair symbols.

  {
      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:237-267 (registration)

  Complete registration of the get_24hr_ticker tool using server.tool() method. Includes the tool name, input validation schema, and the async handler function that makes the API call to Binance.

  // 24hr Price Change Statistics
  server.tool(
      "get_24hr_ticker",
      {
          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/24hr`, {
                  params,
                  ...getProxyConfig(),
              });
              return {
                  content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
              };
          } catch (error: any) {
              return {
                  content: [{ type: "text", text: `Failed to get 24hr price statistics: ${error.message}` }],
                  isError: true
              };
          }
      }
  );

• src/index.ts:406-434 (helper)

  Helper function getProxyConfig() that configures proxy settings for HTTP requests. It prioritizes SOCKS5 proxy (if SOCKS_PROXY or SOCKS5_PROXY env var is set), falls back to HTTP proxy (if HTTP_PROXY or HTTPS_PROXY env var is set), and returns an empty object if no proxy is configured.

  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 {};
  }

• src/index.ts:9-13 (helper)

  Base configuration constants used by the get_24hr_ticker handler: BASE_URL for the Binance API endpoint, and environment variable configurations for HTTP and SOCKS proxy support.

  const BASE_URL = "https://api.binance.com";
  
  // 支持多种代理类型
  const httpProxyURL = process.env.HTTP_PROXY || process.env.HTTPS_PROXY;
  const socksProxyURL = process.env.SOCKS_PROXY || process.env.SOCKS5_PROXY;
