Context7
Feeds AI the latest docs for libraries and frameworks before it answers, so code it writes does not use outdated, removed functions.
Description from the maker (original English)
Search Rakuten Ichiba products and compare prices via Claude. Zero setup, no API key needed.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (0.4.0) reached the registry 6 months ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

設定不要・APIキー不要・無料。 URL を一つ追加するだけで、Claude から楽天市場のおすすめ商品検索・最安値比較・出張ホテル予約ができるようになります。
対応地域: 楽天市場は日本国内のサービスです。HoShy も日本在住・日本の楽天市場で買える商品が前提です。

Claude: (実質価格・ポイント還元込みで候補を提示)
あなた: 「Anker PowerCore 10000 の最安値どこ?送料とポイント込みで」
Claude: (楽天市場内のショップを横断して実質最安を回答)
あなた: 「来週の火・水に大阪出張。梅田駅から徒歩10分以内、1泊6000円以下で空いてるビジネスホテル探して」
Claude: (Google Maps で実際の徒歩時間を測って条件に合う空室だけ提示)
Claude が文脈から適切なツールを自動で選ぶので、ツール名を覚える必要はありません。いつも通り日本語で話しかけるだけ。
サーバー URL はこれ一つだけ:
https://hoshy.negimaru1025.workers.dev/mcp
お使いの Claude に合わせて、以下のいずれかの方法で追加してください。
→ [claude.ai のコネクタ設定を開く](https://claude.ai/customize/connectors)
または手動で:
https://hoshy.negimaru1025.workers.dev/mcp を入力して保存無料プランでもカスタムコネクタ 1 件が使えます。Pro/Max/Team プランではさらに多数追加可能です。
ターミナルで以下を一行実行するだけです。
claude mcp add --transport http hoshy https://hoshy.negimaru1025.workers.dev/mcp
設定ファイルに以下を追記して、Claude Desktop を再起動してください。
{
"mcpServers": { "hoshy": { "type": "http", "url": "https://hoshy.negimaru1025.workers.dev/mcp" } } }
設定ファイルの場所:
~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json以上で接続完了です。API キーの取得・アカウント登録は一切ありません。
Claude が自動で選ぶので、名前を覚える必要はありません。参考までに:
キーワードと予算から、楽天市場の中でレビュー評価が高く、ポイント還元込みの実質価格がお得な商品を上位 N 件返します。
話しかけ方の例:
商品名や型番で、楽天市場内のショップを横断して最安値を比較します。送料・ポイント還元込みの「実質価格」で順位付けするので、表示価格のトリックに惑わされません。
話しかけ方の例:
目的地・日程・予算・移動時間を指定すると、Google Maps で実際の移動時間を計測したうえで、徒歩または電車で指定分以内に着ける空室ホテルだけを返します。
「駅から徒歩10分」「1泊6000円以下」「今週の火水」みたいなリアルな条件に一発で答えます。
話しかけ方の例:
HoShy は無料で公開していますが、開発・運用には楽天・Cloudflare・Google Maps の利用料がかかっています。そのため、返ってくる商品リンクは楽天アフィリエイト経由になっています。
