post_nowLABSCO SUMMARY
Cross-posting without the copy-paste tax.
The value sits in the rewrite: one announcement leaves as fourteen differently-worded posts rather than one that reads awkwardly on thirteen of them. Scheduling and the generated calendar mean a month of posts can be settled in one sitting.
What it is
An npm MCP server for the Atlas social posting service, fanning one message out to Twitter/X, Instagram, TikTok, Facebook, LinkedIn, YouTube, Threads, Pinterest, Reddit, Bluesky, Telegram, Google Business, Snapchat and WhatsApp.
What you get
- One message posted to every connected account at once, rewritten per platform — a short punchy line for Twitter, a longer piece for LinkedIn
- Posts scheduled for a future date and time instead of going out immediately
- A 30-day content calendar generated with daily topics, hooks and per-platform recommendations
- Performance figures pulled back across all connected platforms
- Recent post history with the status of each
- The list of accounts that are actually connected, so you know what 'all platforms' currently means
Requirements
npx -y atlas-social-mcp, no build step. ZERNIO_API_KEY is the only required key: it comes from a Zernio account, with your social accounts connected in its dashboard. ANTHROPIC_API_KEY is optional; without it, posts go out with your original text on every platform and the 30-day calendar cannot be generated.

USE CASES
01
Announcing a launch everywhere at once
Send the news once and let each platform get a version shaped for it.
02
Lining up next week on a quiet afternoon
Queue posts against specific dates and times instead of remembering to publish them.
03
Filling a month when the ideas have run out
Generate 30 days of topics and hooks, with a suggestion of which platform each belongs on.
04
Finding out which platform actually carried it
Pull performance numbers across every connected account in one view rather than five dashboards.
05
Checking what went out while you weren't looking
Read recent post history and status, and confirm which accounts are still connected.

ANTHROPIC_API_KEY is optional: add "ANTHROPIC_API_KEY": "sk-ant-..." to env to have each post rewritten per platform and to generate calendars. Without it, posts go out with your original text.
