How to add Upload-Post to Claude

  1. In Claude on the web or desktop, open Customize, then Connectors (Settings > Connectors in some versions).
  2. Press + Add, then Add custom connector.
  3. Name it Upload-Post, paste the address and press Continue.
  4. Under Request headers, add the header Authorization with the value ApiKey YOUR_KEY, your key in place of YOUR_KEY. Press Add. The registry entry says the key is optional: you can also leave the header out and sign in when you connect.
  5. Press Connect next to it and sign in if it asks.
  6. In a chat, press +, then Connectors, to switch it on.

On your phone: connectors belong to your Claude account. Add it once on claude.ai or in the desktop app, and it is in the Claude app for iPhone and Android too: in a chat, press +, then Connectors, and switch it on.

Claude's free plan allows one custom connector; paid plans allow more. On Team and Enterprise plans an owner adds it once under Organization settings > Connectors, and each member then presses Connect. Claude's help page

How to add it to ChatGPT

  1. On chatgpt.com, on a Plus, Pro, Business, Enterprise or Edu plan, turn on Developer mode (Settings > Security and login, or Settings > Apps > Advanced settings in some versions).
  2. Open Settings > Apps and create an app (the + or Create button).
  3. Name it Upload-Post, paste the address, choose OAuth (or No authentication if the server is open) and press Create.
  4. Sign in when it asks.
  5. In a new chat, press + and pick Upload-Post.

ChatGPT's custom apps cannot send a key header; choose OAuth, which the registry entry says this server also offers.

ChatGPT's menus move now and then; the idea stays the same: a new app, this address, OAuth. On business plans an admin may have to allow custom apps first.

Claude Code

claude mcp add --transport http upload-post https://mcp.upload-post.com/mcp --header "Authorization: ApiKey YOUR_KEY"

Put your key in place of YOUR_KEY. The key is optional here: leave out --header and run /mcp to sign in instead.
