Substack + ChatGPT

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

Voraussetzungen

Die vollständige Setup-Anleitung ist in den Connector eingebaut (im Store sichtbar, wenn du den Connector auswählst). Benötigte Umgebungsvariablen für diesen Connector:

SUBSTACK_PUBLICATION_URL

Schritt 1 — Zugangsdaten holen

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)

Schritt 2 — Adapter installieren

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

Schritt 3 — Connector in ChatGPT hinzufügen

ChatGPT unterstützt MCP-Server über die Connectors-Funktion (Plus-/Pro-/Team-/Enterprise-Pläne). Der kostenlose Tarif unterstützt keine eigenen Connectors.

  1. Öffne ChatGPT → Einstellungen → Connectors (oder klicke das 🔧-Icon im Composer → Manage connectors).
  2. Klicke "Add custom connector".
  3. Trage ein:
    • Name: Substack
    • MCP server URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer Token → MCP-API-Key einfügen (aus AnythingMCP → Profile → MCP API Keys → New Key)
  4. Klicke Connect zum Autorisieren.
