PostMCP AI is an AI social media manager and open-source MCP server that drafts, schedules and publishes posts to seven networks via Claude, ChatGPT or Cursor.
About
PostMCP AI is an AI social media manager and auto-posting tool that writes, schedules, publishes and measures posts across seven networks from a single workspace. It addresses a common pain point for creators and small marketing teams: rewriting the same message in different tones for each platform, juggling multiple scheduling tools, and losing track of what was published where.
The product works two ways. Humans get a web dashboard with a drag-and-drop calendar, AI copywriting and analytics, plus a companion mobile app for Android (iOS listed as coming soon). AI assistants such as Claude, ChatGPT and Cursor connect to the same engine through an open-source, MIT-licensed MCP server published as the npm package @postmcpai/server, which can run locally over stdio or connect to a hosted endpoint over HTTP. A REST API and OpenAPI schema are also available for custom integrations.

Who It's For
PostMCP AI suits solo creators, social media managers and small marketing teams who maintain a presence on several networks at once. It is also aimed at developers and AI-automation builders who want to drive social publishing from assistants like Claude, ChatGPT or Cursor through MCP, or from their own scripts via the REST API. Agencies managing multiple client accounts can use isolated workspaces with role-based access. People who only post occasionally to a single platform will likely find the free tier sufficient, while high-volume publishers will need a paid plan for the larger credit allowances.
