Zernio for Claude Code

Schedule, publish, and analyze social media across 16 platforms (Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Threads, Pinterest, Reddit, Bluesky, WhatsApp, Telegram, Snapchat, Google Business, Discord, Slack) directly from Claude Code, plus a unified inbox, paid-ads management, and analytics. Powered by Zernio's hosted MCP server (300+ tools).

Install

/plugin marketplace add zernio-dev/zernio-claude-plugin
/plugin install zernio@zernio

Then run /mcp, pick zernio, and sign in. Your browser opens the Zernio consent screen, you approve, and Claude Code stores the token. There's no API key to copy.

Already have a Zernio account? That's the one you sign in with. If you don't, create it during the flow.

What you can do

• "List my connected social accounts" (/zernio:accounts)
• "Schedule a LinkedIn post for tomorrow at 9am: ..."
• "Cross-post this to X, LinkedIn, and Bluesky right now"
• "Show my unread Instagram DMs"
• "What's the best time to post this week?"
• "List my active Meta ad campaigns and their spend"

How it works

This plugin bundles a single remote MCP server, https://mcp.zernio.com/mcp (Streamable HTTP), authenticated with OAuth 2.0 (PKCE). No local install or Python required, and the tool list comes from the server, so new Zernio endpoints show up without updating the plugin.

Tokens are short-lived and refresh automatically. Revoke access any time from zernio.com/dashboard; that kills this client alone and leaves your API keys and other integrations untouched.

Headless and CI

claude -p and Agent SDK runs can't open a browser, so a machine that has never signed in can't complete OAuth. Two options:

• Sign in once interactively on that machine (claude mcp login zernio). The stored token refreshes on its own from then on.

• Or skip the plugin and configure the server with an API key, which needs no browser:

  claude mcp add --transport http zernio https://mcp.zernio.com/mcp \
    --header "Authorization: Bearer sk_your_key"
  

  Create a key at zernio.com/dashboard/api-keys.
