Substack + Claude

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

前提条件

完整的设置说明已内置在连接器中 (在 store 中选择连接器时可见)。所需环境变量:

SUBSTACK_PUBLICATION_URL

步骤 1 — 获取凭证

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)

步骤 2 — 安装 adapter

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

步骤 3 — 在 Claude 中添加连接器

推荐路径 — 在 claude.ai web 上工作，无需触碰任何配置文件。

打开 claude.ai/customize/connectors。
点击 "Add custom connector"。
填入:
- Name: Substack
- URL: https://cloud.anythingmcp.com/mcp
- Authentication: Bearer token → 粘贴你的 MCP API key (来自 AnythingMCP → Profile → MCP API Keys → New Key)
点击 Connect 授权。
