   Add this to .cursor/mcp.json, with your key in place of pmx_….

   {
     "mcpServers": {
       "postmaxx": {

         "headers": { "Authorization": "Bearer pmx_…" }
       }
     }
   }

3. 3

   Ask it to post. It sees your accounts, saves drafts, schedules them and tells you each result.

Things to ask

• “Write a launch post for the release we just shipped and save it as a draft for every account.”
• “Schedule the draft for tomorrow at 9 am.”
• “How did last week’s posts do?”
• “Which accounts are connected, and does any need reconnecting?”
