Implementation Reference
- src/server.ts:314-325 (handler)MCP tool handler for getPrice that parses input arguments using the schema and delegates execution to the BitgetRestClient's getPrice method, returning formatted result.
case 'getPrice': { const { symbol } = GetPriceSchema.parse(args); const price = await this.bitgetClient.getPrice(symbol); return { content: [ { type: 'text', text: `Current price for ${symbol}: $${price}`, }, ], } as CallToolResult; } - src/types/mcp.ts:9-11 (schema)Zod schema defining the input parameters for the getPrice tool (symbol string). Used for validation in the handler.
export const GetPriceSchema = z.object({ symbol: z.string().describe('Trading pair symbol (e.g., BTCUSDT for spot, BTCUSDT_UMCBL for futures)') }); - src/server.ts:103-113 (registration)Registration of the getPrice tool in the listTools handler, providing name, description, and input schema for MCP discovery.

Handles caching, spot vs futures logic, API requests to Bitget, and error handling.
