Tools

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

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

Pricing

Atlas Social MCP is free and open source.

You'll need a Zernio account for the posting API:
