# 自作PC NAVI — Jisaku PC NAVI

> A Japanese PC parts planning website. Visitors can build and edit a PC configuration by budget and purpose, search public parts, and check compatibility. Prices are in Japanese yen (JPY).

AI agents with WebMCP support can open https://jisaku-pc-navi.com/builder and discover the page's tools after saved configurations finish loading. Tools share the visitor's current configuration, settings and saving behavior with the normal interface. This file provides guidance; it does not itself enable tool execution or grant access.

AI向け案内：予算・用途・固定パーツ・詳細設定・ゲーム条件を指定して構成を検討できます。操作方法は下記ガイドを参照してください。対応環境では、ページが提供する最新のツール説明と入力仕様を確認してから操作してください。

Prices may require confirmation. Unknown compatibility is not the same as verified compatibility. A selected target FPS is not proof of measured performance. Keep warnings in the answer. Configuration generation does not purchase parts or publish a shared configuration.
