The social scheduler even your AI can run.
The social scheduler even your AI can run.
Postbase is an open-source, MCP-native social media scheduler. Connect your channels, compose and schedule posts, and Postbase publishes them across every channel on time — from a clean dashboard, or straight from the AI tools you already work in.
- Publishing rail, not a content generator — it schedules and publishes; it doesn't write your content. - MCP-native — an AI agent (Claude, Cursor, …) can drive posting through the @postbasehq/mcp server. - Self-host free, or use the hosted cloud — same product either way.
Channels: X, Instagram, LinkedIn, TikTok · YouTube next.
- Next.js (App Router) + TypeScript + Tailwind - Supabase — Postgres, Auth, Storage - Vercel Cron — scheduled-publishing poller - @postbasehq/mcp — MCP server (npm)
Apply the database schema in supabase/migrations/ (via the Supabase SQL editor or the CLI). To run the scheduled publisher locally (polls the publish endpoint):
In production, a Vercel Cron job hits /api/cron/publish every minute (vercel.json), so no separate worker is needed.
Add Postbase to your AI client and let an agent schedule posts for you. The MCP server lives in its own repo: postbasehq/mcp (published as @postbasehq/mcp on npm). Tools: listchannels, createpost, listscheduled, cancelpost.
The MCP server is maintained separately at postbasehq/mcp.
