Social By InstantDM is a social media scheduling tool that allows users to plan, schedule, and analyze posts across multiple social networks from a single workspace. The supported platforms include Instagram, X, LinkedIn, TikTok, Facebook, Pinterest, Threads, and YouTube. The tool provides several methods for content creation and publishing. Users can post manually through a web interface. It also integrates with AI agents through the Model Context Protocol (MCP), allowing platforms like ChatGPT and Claude Code to draft, schedule, and publish content. A signed REST API is available for direct programmatic access, and native nodes are provided for automation platforms such as n8n and Make. The platform uses scoped API keys that can be generated, rotated, and revoked from the dashboard to control access. Typical use cases include managing content for agencies, integrating social posting into automated workflows or CI/CD pipelines, and enabling AI agents to handle publishing tasks. The API supports sending posts to multiple platforms in a single request with per-platform captions and scheduling times. Publish events trigger signed webhooks with retry and backoff. Insights and analytics are accessible through the same API and MCP interfaces.
