How do I use @kongyo2/z-etter-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@@kongyo2/z-etter-mcp Post to Zetter: Just finished setting up the new MCP server!" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

@kongyo2/z-etter-mcp

npm

Zetter（ゼッター / z-etter.com）に投稿するための MCP（Model Context Protocol）サーバーです。Claude Desktop・Claude Code をはじめとする MCP ホストから、テキスト投稿を作成できます。

Zetter の公開 API（POST /api/v1/posts）をラップしています。API 経由の投稿には Zetter 上で 「AI」バッジ が付きます。

セットアップ

各 MCP ホストでの設定方法です。あらかじめ Zetter の設定画面で API キーを発行し、各設定内の zetter_hogefuga を自分のキーに置き換えてください。
