Connect ChatGPT
Add Voxmin to ChatGPT as a custom MCP server and sign in with your Voxmin account, so ChatGPT can make pictures, songs and karaoke with your Voxmin credits.
ChatGPT
ChatGPT connects to MCP servers in Developer mode, signing in with OAuth. It cannot send a personal token, so you sign in with your Voxmin account.
Before you start
- A Voxmin account with some credits.
- ChatGPT on the web, on a plan with Developer mode (Plus, Pro, Business, Enterprise or Edu). On Business and Enterprise, an admin may need to allow custom MCP connectors first.
Add Voxmin
Turn on Developer mode
In ChatGPT on the web, open Settings and turn on Developer mode. Depending on your version, it is under Apps & Connectors → Advanced settings, or under Security.
Add a custom MCP server
Add a custom MCP server (it may be called a connector, an app or a plugin). Name it Voxmin, paste the MCP server URL, and choose OAuth for authentication:
https://api.voxmin.com/auth/mcp
Create it and sign in
Create it, then connect. ChatGPT opens Voxmin: log in if you are asked, check that the page names ChatGPT, and choose Approve.
Check it works
- In a new chat, add Voxmin from the tools (the + menu).
- Ask: "What's my Voxmin balance?" ChatGPT calls
get_accountand answers with your credits. - ChatGPT asks before it uses a tool that changes something. Read the price in the request before you allow a spending tool.
Voxmin shows ChatGPT under AI Integrations → Connected apps. Sign out there stops it at once.
Troubleshooting
| What you see | Why | What to do |
|---|---|---|
| No way to add an MCP server | Developer mode is off, or not on your plan or workspace | Turn it on in Settings, or ask your workspace admin |
| The Voxmin page says the sign-in has ended | It waited more than 10 minutes, or was already answered | Connect again from ChatGPT |
| Voxmin stopped working | It was signed out on Voxmin, or not used for 90 days | Reconnect it in ChatGPT |
| "Not enough credits" | Your balance is lower than the tool's price | Top up on the Pricing page |
429 Too Many Requests | More than 60 requests in a minute | Wait a minute and try again |
| The request is refused | It did not pass Voxmin's content checks | Change the request. A refused picture is not charged |
To call Voxmin from your own code with OpenAI's API, see the OpenAI Responses API guide instead. See the overview for every tool, its price and how billing works.
