Run PosterAI from Claude
PosterAI ships an MCP server, so you can draft, schedule and manage posts across Instagram, TikTok and LinkedIn just by chatting with Claude — no dashboard required.
Setup
Requires Node.js 18+. There's nothing to install manually — npx fetches the posterai-mcp package automatically.
How to install Node.js
Check what you have: node --version (should be 18 or higher). If it's missing or older, install it via:
- Download the LTS installer from nodejs.org (works on macOS, Windows and Linux).
- macOS (Homebrew):
brew install node - Windows (winget):
winget install OpenJS.NodeJS.LTS - Linux / version manager: nvm →
nvm install 20
