Quick Start
Install via npx (recommended)
Add to your Claude Code MCP config (~/.claude/settings.json):
{
"mcpServers": {
"atlas-social": {
"command": "npx",
"args": ["-y", "@runatlas/atlas-social-mcp"],
"env": {
"ZERNIO_API_KEY": "sk_your_key_here",
"ANTHROPIC_API_KEY": "sk-ant-your_key_here"
}
}
}
}
Or for Claude Desktop (claude_desktop_config.json):
{
"mcpServers": {
"atlas-social": {
"command": "npx",
"args": ["-y", "@runatlas/atlas-social-mcp"],
"env": {
"ZERNIO_API_KEY": "sk_your_key_here",
"ANTHROPIC_API_KEY": "sk-ant-your_key_here"
}
}
}
}
Restart Claude Code. Done.
Usage
Just talk naturally:
"Post our new product launch to all platforms"
"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. |
generate_calendar | 30-day content calendar with AI. |
get_analytics | Performance metrics across platforms. |
get_recent_posts | Recent post history and status. |
list_accounts | Connected social accounts. |
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_KEYfor 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.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
