Binance Cryptocurrency MCP

Implementation Reference

• src/index.ts:51-69 (handler)

  Handler function that executes get_recent_trades - makes an API call to Binance's /api/v3/trades endpoint with symbol and limit parameters, returns formatted JSON response or error

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

• src/index.ts:47-50 (schema)

  Schema definition for get_recent_trades tool - defines required symbol parameter and optional limit parameter with zod validation

  {
      symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT"),
      limit: z.number().optional().describe("Number of trades to return, default 500, max 1000")
  },

• src/index.ts:45-70 (registration)

  Tool registration for get_recent_trades - registers the tool with the MCP server including name, schema, and async handler function

  server.tool(
      "get_recent_trades",
      {
          symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT"),
          limit: z.number().optional().describe("Number of trades to return, default 500, max 1000")
      },
      async (args: { symbol: string; limit?: number }) => {
          try {
              const response = await axios.get(`${BASE_URL}/api/v3/trades`, {
                  params: {
                      symbol: args.symbol,
                      limit: args.limit
                  },
                  ...getProxyConfig(),
              });
              return {
                  content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }]
              };
          } catch (error: any) {
              return {
                  content: [{ type: "text", text: `Failed to get recent trades: ${error.message}` }],
                  isError: true
              };
          }
      }
  );
