Implementation Reference

• src/bitThumb/index.ts:244-258 (handler)

  Core handler function implementing the logic to place a limit order by calling Bithumb's trade API endpoint.
  public async postPlace( orderCurrency: string, units: number, price: number, type: tradeType, ): Promise<IPostPlace> { const param = { order_currency: orderCurrency, units, price, type, }; const res = <IPostPlace>await this.requestTrade('place', param); return res; }
• src/index.ts:363-370 (handler)

  MCP server tool call handler that receives 'post_place' invocations and delegates to the ApiBithumb instance.
  case 'post_place': result = await this.bithumbApi.postPlace( args.orderCurrency as string, args.units as number, args.price as number, args.type as tradeType // Cast to expected type ); break;
• src/index.ts:210-222 (registration)

  Tool registration in the MCP server's tools list, including name, description, and input schema.
