Substack Gateway OSS

REST API and MCP gateway for reading Substack profiles, posts, and notes, plus publishing.

Servicefree

Substack Gateway OSS exposes a Substack account's posts, notes, and publishing workflow through a REST API and MCP server, so an AI assistant or custom app can read and publish Substack content programmatically. It's for Substack writers and developers who want to automate or integrate their Substack presence with other tools.
