Instructions

Implementation Reference

• src/interface/controllers/GeneralToolsController.ts:39-51 (registration)

  Registers the 'get-historical-price' MCP tool with input schema (date: YYYY-MM-DD) and thin handler that delegates to GeneralService.getHistoricalPrice.
  private registerGetHistoricalPriceHandler(): void { this.server.tool( "get-historical-price", "Returns the BTC price for a specific date (YYYY-MM-DD)", { date: z.string().regex(/^\d{4}-\d{2}-\d{2}$/).describe("The date in YYYY-MM-DD format") }, async ({ date }) => { const text = await this.generalService.getHistoricalPrice(date); return { content: [{ type: "text", text }] }; } ); }
• src/infrastructure/services/requests/GeneralRequestService.ts:14-17 (handler)

  Core handler implementation: performs the API request to fetch historical BTC price for the given date.
  async getHistoricalPrice(date: string): Promise<any | null> { // date format: YYYY-MM-DD return this.client.makeRequest<any>(`historical-price/${date}`); }
• src/application/services/GeneralService.ts:17-20 (helper)

  Application service helper that delegates to infrastructure request service and formats the response.
  async getHistoricalPrice(date: string): Promise<string> { const data = await this.requestService.getHistoricalPrice(date); return formatResponse<any>("Historical Price", data); }
