Implementation Reference
- src/tools/market-tools.ts:20-46 (handler)The core handler function for the 'fetchMarkets' tool. It retrieves a public CCXT exchange instance, loads the markets, and returns the data as a JSON string or an error response.async ({ exchangeId }) => { try { // 공개 인스턴스 사용 const exchange = ccxtServer.getPublicExchangeInstance(exchangeId); const markets = await exchange.loadMarkets(); return { content: [ { type: "text", text: JSON.stringify(markets, null, 2) } ] }; } catch (error) { return { content: [ { type: "text", text: `Error fetching markets: ${(error as Error).message}` } ], isError: true }; } } );
- src/tools/market-tools.ts:17-19 (schema)Input schema using Zod for the 'fetchMarkets' tool, requiring an 'exchangeId' string parameter.{ exchangeId: z.string().describe("Exchange ID (e.g., 'binance', 'coinbase')") },
- src/tools/market-tools.ts:15-46 (registration)Direct registration of the 'fetchMarkets' tool on the MCP server using server.tool(), specifying name, description, input schema, and handler function."fetchMarkets", "Fetch markets from a cryptocurrency exchange", { exchangeId: z.string().describe("Exchange ID (e.g., 'binance', 'coinbase')") }, async ({ exchangeId }) => { try { // 공개 인스턴스 사용 const exchange = ccxtServer.getPublicExchangeInstance(exchangeId); const markets = await exchange.loadMarkets(); return { content: [ { type: "text", text: JSON.stringify(markets, null, 2) } ] }; } catch (error) { return { content: [ { type: "text", text: `Error fetching markets: ${(error as Error).message}` } ], isError: true }; } } );
- src/server.ts:372-372 (registration)Invocation of registerMarketTools in CcxtMcpServer's registerTools() method, which ultimately registers the 'fetchMarkets' tool.registerMarketTools(this.server, this);
