substack-mcp-plus and substack-publisher-mcp
The first is an unofficial reverse-engineered client with browser automation, while the second is an official API wrapper—they're competitors offering overlapping Substack integration, though the official one may have better long-term reliability and the unofficial one may offer broader feature coverage.
