Overview
What is Socialync?
Socialync is an MCP server that lets AI assistants draft, schedule, and publish image and text content across a creator's connected social accounts. Users authorize each platform once via official OAuth flows, then their AI can prepare posts, schedule them, save drafts for review, and pull analytics—all through standard MCP tools.
How to use Socialync?
Sign up at socialync.io and upgrade to the Business plan ($40/month). Connect your social accounts through Socialync's official OAuth flow for each platform, then generate an API key from your settings page. Add the MCP server to your client config with the given URL, HTTP transport, and Authorization: Apikey YOUR_SOCIALYNC_API_KEY header. Once configured, instruct your AI assistant to draft, schedule, cross-post, or pull analytics for your connected accounts.
