Prerequisites

• Chrome logged in to Substack as the publication owner (one-time manual setup by the writer).
• Claude-in-Chrome MCP tools available: tabs_context_mcp, tabs_create_mcp, navigate, get_page_text, read_page, optionally javascript_tool.
• Publication URL known: https://thethinkersnotebook.substack.com/publish/stats (the dashboard URL shape — verify on first run).
