@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。

Claude Code

claude mcp add --transport stdio --scope user --env ZETTER_API_KEY=zetter_hogefuga zetter -- npx -y @kongyo2/z-etter-mcp

OpenAI Codex

codex mcp add --env ZETTER_API_KEY=zetter_hogefuga zetter -- npx -y @kongyo2/z-etter-mcp

~/.codex/config.toml に直接記述する場合:

[mcp_servers.zetter]
command = "npx"
args = ["-y", "@kongyo2/z-etter-mcp"]
env = { ZETTER_API_KEY = "zetter_hogefuga" }

Available Tools

1 tool
create_postCreate Zetter PostA

Publish a plain-text post to Zetter (z-etter.com), a Japanese microblogging SNS. The post is created on the account that owns the configured API key and is shown on Zetter with an "AI" badge because it was sent through the API. Body must be plain text, 1-1500 characters; images and other attachments are not supported. Returns the created post's identifier when the API provides one. Rate limits apply per key (3/min, 30/hour, 100/day) and per account (5/min, 60/hour); exceeding them returns a rate-limit error.

Inputs: content (required).

    Disambiguation5/5

    Only one tool exists, so there is no possibility of confusion between tools.

    Naming Consistency5/5

    With a single tool, the naming is trivially consistent. The verb_noun pattern (create_post) is clear.

    Tool Count2/5

    A single tool feels insufficient for a microblogging platform. Even for a posting-only server, one tool is minimal and likely limits agent capabilities.

    Completeness2/5

    Only a create post operation is provided. Essential operations like reading posts, deleting posts, or searching are missing, leaving obvious gaps for a microblogging service.
