Implementation Reference
- src/index.ts:147-182 (handler)The main execution logic for the 'get_price' tool. It queries the OKX /market/ticker API, handles errors, extracts the ticker data, and returns a formatted JSON response with instrument details, prices, and timestamp.
if (request.params.name === 'get_price') { console.error(`[API] Fetching price for instrument: ${args.instrument}`); const response = await this.axiosInstance.get<OKXTickerResponse>( '/market/ticker', { params: { instId: args.instrument }, } ); if (response.data.code !== '0') { throw new Error(`OKX API error: ${response.data.msg}`); } if (!response.data.data || response.data.data.length === 0) { throw new Error('No data returned from OKX API'); } const ticker = response.data.data[0]; return { content: [ { type: 'text', text: JSON.stringify({ instrument: ticker.instId, lastPrice: ticker.last, bid: ticker.bidPx, ask: ticker.askPx, high24h: ticker.high24h, low24h: ticker.low24h, volume24h: ticker.vol24h, timestamp: new Date(parseInt(ticker.ts)).toISOString(), }, null, 2), }, ], }; } else { - src/index.ts:84-97 (registration)Registers the 'get_price' tool in the MCP listTools handler, specifying its name, description, and input schema requiring an 'instrument' parameter.
