How Content Adaptation Works

When you say "Post this to Twitter and LinkedIn", Atlas Social:

1. Takes your message
2. Rewrites for Twitter: punchy, under 240 chars, 1-2 hashtags
3. Rewrites for LinkedIn: professional, 200 words, thought leadership angle
4. Posts both versions simultaneously

Each platform gets content that feels native — not a copy-paste resize.

Setup

1. Get a Zernio API key (free tier available): zernio.com
2. Connect your social accounts in the Zernio dashboard
3. Add the MCP server to your Claude config (see Quick Start above)
4. Optional: Add ANTHROPIC_API_KEY for AI content adaptation and calendar generation

API Keys

Key	Required	Get it from
ZERNIO_API_KEY	Yes	zernio.com → Dashboard → API Keys
ANTHROPIC_API_KEY	Optional	console.anthropic.com

Without ANTHROPIC_API_KEY, posts will use your original text on all platforms (no per-platform adaptation). Calendar generation requires it.
