Implementation Reference

• src/index.ts:212-235 (registration)

  Tool registration for get_avg_price using server.tool() with zod schema definition and async handler function

  server.tool(
      "get_avg_price",
      {
          symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT")
      },
      async (args: { symbol: string }) => {
          try {
              const response = await axios.get(`${BASE_URL}/api/v3/avgPrice`, {
                  params: {
                      symbol: args.symbol
                  },
                  ...getProxyConfig(),
              });
              return {
                  content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
              };
          } catch (error: any) {
              return {
                  content: [{ type: "text", text: `Failed to get average price: ${error.message}` }],
                  isError: true
              };
          }
      }
  );

• src/index.ts:217-234 (handler)

  Handler function that executes get_avg_price by making a GET request to Binance API /api/v3/avgPrice endpoint with symbol parameter, handles errors and returns JSON response

  async (args: { symbol: string }) => {
      try {
          const response = await axios.get(`${BASE_URL}/api/v3/avgPrice`, {
              params: {
                  symbol: args.symbol
              },
              ...getProxyConfig(),
          });
          return {
              content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
          };
      } catch (error: any) {
          return {
              content: [{ type: "text", text: `Failed to get average price: ${error.message}` }],
              isError: true
          };
      }
  }

• src/index.ts:214-216 (schema)

  Zod schema definition for get_avg_price input parameters: symbol (string, required) describing trading pair symbol like BTCUSDT

  {
      symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT")
  },

• src/index.ts:406-434 (helper)

  getProxyConfig() helper function that configures SOCKS5 or HTTP proxy for axios 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 {};
  }
