Substack + Gemini
Read Substack publication content, posts, comments, podcast episodes via public RSS/JSON feeds. 5 tools, no auth required.
Requisitos previos
Las instrucciones de configuración completas están incluidas en el conector (visibles en el store al seleccionarlo). Las variables de entorno requeridas:
SUBSTACK_PUBLICATION_URL
Paso 1 — Obtener credenciales
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)
Paso 2 — Instalar el adapter
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
Paso 3 — Añadir el conector en Gemini
Gemini CLI lee servidores MCP desde ~/.gemini/settings.json (o %APPDATA%\gemini\settings.json en Windows). Añade:
{
"mcpServers": {
"anythingmcp": {
"httpUrl": "https://cloud.anythingmcp.com/mcp",
"headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
}
}
}
