Substack Publisher MCP

MCP server for Substack's official Publisher API to check post analytics and subscribers from AI clients.

Pluginfree

Substack Publisher MCP is an MCP server that connects Substack's official Publisher API to AI clients like Claude Desktop and Cursor, letting a publisher ask their AI assistant for post analytics, subscriber counts, and publication data instead of checking the Substack dashboard directly. It supports managing more than one publication from a single setup. It is intended for Substack publishers who already use an MCP-compatible AI client and have Publisher API access enabled.
