Implementation Reference
- src/index.ts:183-205 (handler)Handler function for the 'get_ui_klines' tool. Fetches UI K-line (candlestick) data from the Binance API endpoint '/api/v3/uiKlines' using axios, with parameters passed from input args, and returns the JSON response or error message.async (args: { symbol: string; interval: string; startTime?: number; endTime?: number; timeZone?: string; limit?: number }) => { try { const response = await axios.get(`${BASE_URL}/api/v3/uiKlines`, { params: { symbol: args.symbol, interval: args.interval, startTime: args.startTime, endTime: args.endTime, timeZone: args.timeZone, limit: args.limit }, proxy: getProxy(), }); return { content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }] }; } catch (error: any) { return { content: [{ type: "text", text: `Failed to get UI K-line data: ${error.message}` }], isError: true }; } }
- src/index.ts:175-182 (schema)Zod input schema defining parameters for the 'get_ui_klines' tool: symbol, interval, optional startTime, endTime, timeZone, and limit.{ symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT"), interval: z.string().describe("K-line interval, e.g. 1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 6h, 8h, 12h, 1d, 3d, 1w, 1M"), startTime: z.number().optional().describe("Start timestamp (milliseconds)"), endTime: z.number().optional().describe("End timestamp (milliseconds)"), timeZone: z.string().optional().describe("Time zone, default UTC"), limit: z.number().optional().describe("Number of K-lines to return, default 500, max 1000") },
- src/index.ts:173-206 (registration)Registration of the 'get_ui_klines' tool on the MCP server using server.tool(name, schema, handler), within the registerTools function.server.tool( "get_ui_klines", { symbol: z.string().describe("Trading pair symbol, e.g. BTCUSDT"), interval: z.string().describe("K-line interval, e.g. 1m, 3m, 5m, 15m, 30m, 1h, 2h, 4h, 6h, 8h, 12h, 1d, 3d, 1w, 1M"), startTime: z.number().optional().describe("Start timestamp (milliseconds)"), endTime: z.number().optional().describe("End timestamp (milliseconds)"), timeZone: z.string().optional().describe("Time zone, default UTC"), limit: z.number().optional().describe("Number of K-lines to return, default 500, max 1000") }, async (args: { symbol: string; interval: string; startTime?: number; endTime?: number; timeZone?: string; limit?: number }) => { try { const response = await axios.get(`${BASE_URL}/api/v3/uiKlines`, { params: { symbol: args.symbol, interval: args.interval, startTime: args.startTime, endTime: args.endTime, timeZone: args.timeZone, limit: args.limit }, proxy: getProxy(), }); return { content: [{ type: "text", text: JSON.stringify(response.data, null, 2) }] }; } catch (error: any) { return { content: [{ type: "text", text: `Failed to get UI K-line data: ${error.message}` }], isError: true }; } } );
- src/index.ts:403-412 (helper)Utility function getProxy() that configures proxy settings from proxyURL environment variable, used in the axios requests for all tools including get_ui_klines.function getProxy():any { const proxy: any = {} if (proxyURL) { const urlInfo = new URL(proxyURL); proxy.host = urlInfo.hostname; proxy.port = urlInfo.port; proxy.protocol = urlInfo.protocol.replace(":", ""); } return proxy }
