How I Built a Substack MCP With a Setup Flow That Doesn't Immediately Break

Part 1 of 9

I built substack-mcp-plus because I got tired of brittle Substack tooling and broken setup flows.

The first thing I cared about was simple:
can I connect this thing, confirm it works, and get useful output immediately?

So the first batch focused on:

• list_drafts
• list_published
• get_post_content

That gave me the fastest possible “is this MCP actually alive?” loop after install.

Setup is intentionally simple:

npm i -g substack-mcp-plus
substack-mcp-plus-setup
