Description

This repository implements a Model Context Protocol (MCP) server that fetches and parses public Substack posts, extracting title, author, subtitle, and content. It is intended to run locally (Node.js v18+) and integrates with the Claude.ai desktop app so the assistant can download and summarize Substack articles on demand. The server is lightweight, straightforward to configure, and focuses on providing parsed post content for downstream summarization or analysis.
