PostFiber for OpenAI dots
Made by OpenAI
A dot uses the plugins installed in your ChatGPT account, so you add PostFiber once as a custom MCP server and sign in with OAuth.
Connect over MCP
MCP server address
https://www.postfiber.com/mcpYou sign in to PostFiber and choose the brand OpenAI dots may work in. No API key is needed.
- In ChatGPT, open Plugins, select the plus button and choose Add custom MCP server.
- Enter a name such as PostFiber and, under Connection, the server address.
- Choose OAuth for authentication, accept the risk warning and select Create as a plugin.
- Open the new plugin under your personal plugins and select the plus button to install it. Connect PostFiber when asked: sign in, choose the brand and authorize.
- Ask your dot to list your PostFiber channels. It uses the plugin with the permissions you granted.
Plugins are shared by your dots, ChatGPT, ChatGPT Work and Codex. OpenAI limits custom MCP servers to read access on Pro, so creating and scheduling posts needs a Business, Enterprise or Edu workspace, where the admins decide who may add custom MCP servers.
Try it
- List my connected channels.
- Draft a post about our launch for tomorrow at 9:00 and save it as a draft.
- Show me what is scheduled for this week.
Keep a person in the loop. An agent works with the permissions of the key, or of the person who connected it. Ask it to save drafts or schedule posts, look at the calendar before anything goes out, and give each key only the project and the permissions it needs. A key or a connected app you revoke stops working at once.
