Usage

Just talk naturally:

"Tweet: Just shipped v2.0 — faster, smarter, better."
"Schedule a LinkedIn post for Monday 9am about our hiring news"
"Generate a 30-day calendar for Elite Plumbing"
"Show me this week's analytics"
"What posts went out this week?"
"List my connected accounts"

Tools

Tool	Description
`post_now`	Post immediately. AI adapts content per platform.
`schedule_post`	Schedule for future date/time.

How Content Adaptation Works

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

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

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

Setup

Get a Zernio API key (free tier available): zernio.com
Connect your social accounts in the Zernio dashboard
Add the MCP server to your Claude config (see Quick Start above)
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.
