# PostSider

> Social media scheduling and publishing for humans and AI agents. Plan, schedule and publish across 30+ social networks from one calendar, or hand the exact same publishing actions to an AI agent over MCP, a REST API, or an SDK.

PostSider is a social media management tool with two front doors to the same engine. A human team uses the dashboard, composer and calendar. An AI agent drives the same actions (create a draft, attach media, schedule a post, publish now, read analytics) through the Model Context Protocol (MCP), a REST API, or the `@postsider/node` SDK. The product runs at app.postsider.com and developer docs live at docs.postsider.com. PostSider is made by Lumi Zone (Lukasz Blania).
