Instructions

Implementation Reference

• src/interface/controllers/MempoolToolsController.ts:16-25 (registration)

  Registers the 'get-mempool-info' tool on the MCP server with a handler that calls MempoolService to get info and returns formatted text content.
  private registerGetMempoolHandler(): void { this.server.tool( "get-mempool-info", "Returns mempool info", async () => { const text = await this.mempoolService.getMempoolInfo(); return { content: [{ type: "text", text }] }; } ); }
• src/interface/controllers/MempoolToolsController.ts:20-23 (handler)

  Inline handler function for the 'get-mempool-info' tool that delegates to service and structures MCP response.
  async () => { const text = await this.mempoolService.getMempoolInfo(); return { content: [{ type: "text", text }] }; }
• src/domain/models/responses/mempool/IMempoolResponse.ts:1-5 (schema)

  TypeScript interface defining the structure of mempool info response data used by the tool.
  export interface IMempoolInfoResponse { count: number; vsize: number; total_fee: number; }
• src/application/services/MempoolService.ts:12-15 (helper)

  Application service method that fetches raw mempool info and formats it for the tool response.
  async getMempoolInfo(): Promise<string> { const data = await this.requestService.getMempoolInfo(); return formatResponse<IMempoolInfoResponse>("Mempool Info", data); }
• src/infrastructure/services/requests/MempoolRequestService.ts:11-13 (helper)

  Infrastructure service method performing the HTTP request to the mempool API endpoint.
  async getMempoolInfo(): Promise<IMempoolInfoResponse | null> { return this.client.makeRequest<IMempoolInfoResponse>(`mempool`); }
