PostFiber for Gemini CLI

Connect over MCP

MCP server address

https://www.postfiber.com/mcp

Create an API key in PostFiber under API keys. It is shown once, and it can be limited to one project, to read-only access or to the permissions you choose.

1. Create an API key in PostFiber under API keys.
2. Add the server to Gemini CLI with the settings below.
3. Ask Gemini CLI to list your PostFiber channels to check the connection.

Add this to the settings.json of Gemini CLI (~/.gemini/settings.json) and write your key in place of YOUR_API_KEY:

{
  "mcpServers": {
    "postfiber": {
      "httpUrl": "https://www.postfiber.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

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.
