PostMcpAi

What is PostMcpAi

PostMcpAi is an open-source social media MCP (Model Context Protocol) server that enables AI agents like Claude, ChatGPT, and Cursor to write, schedule, and publish content across seven social networks: X (Twitter), LinkedIn, Instagram, Facebook, Threads, Bluesky, and YouTube Shorts. It provides 16 typed publishing tools that AI assistants can call, allowing users to manage their social media through plain English instructions.

How to use PostMcpAi

1. Connect your accounts: Link your social media accounts (X, LinkedIn, Instagram, etc.) with one click each. Accounts are authorized through each platform's official OAuth 2.0 sign-in, so passwords are never stored.
2. Tell your agent what you want: Type a request in plain English, such as "announce our launch on Friday." The agent writes a tailored post for each network, adjusting tone, length, and hashtags.
3. It posts and manages for you: The agent schedules posts at optimal times, publishes them automatically, and keeps the queue full. You can review drafts before they go out and have final control.
