Posty API, CLI and MCP server

Posty is a social media scheduler from Hungary with a developer surface built for agents and scripts: a streamable-HTTP MCP server (api.posty.hu/mcp), a REST API with an OpenAPI 3 description (posty.hu/openapi.json), OAuth 2.1 with PKCE, HMAC-signed webhooks, and a CLI (npm install -g posty-cli) that ships its own SKILL.md so an agent with a shell needs no docs page. One call schedules a post to Facebook, Instagram, TikTok, LinkedIn, YouTube, X, Threads, Bluesky, Pinterest, Google Business, Discord, Telegram or Slack; the API also lists the queue, finds the next free slot, uploads media and reads analytics. There is no built-in AI writer on purpose: your model writes, Posty publishes. Zero-auth discovery at api.posty.hu/public/v1/status. Product UI in English and Hungarian, docs at posty.hu/fejlesztok. Every plan starts with a 7-day free trial.
