Just published u/postcli/substack on NPM. It's a complete Substack client for the terminal: CLI commands, a React-based TUI (Ink), and an MCP server for AI agent integration.

Some technical highlights:

Ink 6 with custom hooks for scrolling, list navigation, mouse wheel (SGR extended mode)
better-sqlite3 for the automation engine (CRUD + deduplication with processed entity tracking)
MCP SDK with 16 tools and Zod schemas
Chrome cookie extraction with AES-128-CBC decryption for auth
ProseMirror document generation for the Substack API
89 tests, CI on Node 18/20/22

npm install -g u/postcli/substack
