Buffer + ChatGPT

Manage Buffer (social media scheduling: channels, posts, idea queue, analytics) from any AI agent via GraphQL. 8 tools, Bearer token.

前提条件

完全なセットアップ手順はコネクタ自体に組み込まれています (ストアでコネクタを選択すると表示)。必要な環境変数:

BUFFER_ACCESS_TOKEN

ステップ 1 — 認証情報を取得

This connector wraps the Buffer Publish GraphQL API (graphql.buffer.com).

Setup:

  1. Sign in at https://publish.buffer.com → top-right avatar → Settings → API access → Generate personal access token.
  2. Set BUFFER_ACCESS_TOKEN.

Authentication: Authorization: Bearer ${BUFFER_ACCESS_TOKEN}.

GraphQL-only: Buffer's modern API is GraphQL. The auto-injected buffer_graphql_query / buffer_graphql_mutation / buffer_graphql_schema builtins cover anything not in the typed wrappers below.

Channel = connected social account (Twitter, LinkedIn, Facebook, Instagram, Mastodon, TikTok, Pinterest, YouTube, Bluesky, Threads). Each has an ID; posts must specify channelId(s).

…(continued in the in-app connector instructions)

ステップ 2 — アダプターをインストール

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d

ステップ 3 — ChatGPT にコネクタを追加

ChatGPT は Connectors 機能 (Plus / Pro / Team / Enterprise プラン) で MCP サーバーをサポートします。無料プランはカスタムコネクタをサポートしません。

  1. ChatGPT → Settings → Connectors を開きます (またはコンポーザーの 🔧 アイコン → Manage connectors をクリック)。
  2. "Add custom connector" をクリック。
  3. 入力:
    • Name: Buffer
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → MCP API キーを貼り付け
  4. Connect をクリック。
