Substack + Claude

Read Substack publication content, posts, comments, podcast episodes via public RSS/JSON feeds. 5 tools, no auth required.

Предварительные требования

Полные инструкции по настройке встроены в коннектор (видны в магазине при выборе коннектора). Требуемые переменные окружения:

SUBSTACK_PUBLICATION_URL

Шаг 1 — Получите учётные данные

Setup: NO API KEY. Set SUBSTACK_PUBLICATION_URL = the publication's base URL (e.g. https://lennysnewsletter.substack.com). For tools that target a specific publication, the URL is taken from this env var.

Authentication: NONE. All reads use public endpoints (the same JSON Substack's own site fetches).

Content endpoints available:

  • /api/v1/posts?limit=N&offset=M — paginated posts list (each post: id, title, slug, post_date, audience, type)
  • /api/v1/posts/by-id/{id} — single post detail
  • /api/v1/comments/{post_id} — top comments on a post
  • /api/v1/podcast/feed — podcast episodes (audio newsletters only)
  • /feed — standard RSS feed

…(continued in the in-app connector instructions)

Шаг 2 — Установите адаптер

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

Шаг 3 — Добавьте коннектор в Claude

Рекомендуемый путь — работает в claude.ai web без редактирования конфигурационных файлов.

  1. Откройте claude.ai/customize/connectors.
  2. Нажмите "Add custom connector".
  3. Заполните:
    • Name: Substack
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → вставьте ваш MCP API key (из AnythingMCP → Profile → MCP API Keys → New Key)
  4. Нажмите Connect для авторизации.
