Claude Code connects to Voxmin's MCP server directly over HTTP — one command, then sign in with your Voxmin account.
claude mcp add --transport http voxmin https://api.voxmin.com/auth/mcp
Add --scope user to have it in every project, not only this one.
In Claude Code, type /mcp, pick voxmin and choose Authenticate. Your browser opens Voxmin: log in if you are asked, check that the page names Claude Code, and choose Approve.
Voxmin lists Claude Code under AI Integrations → Connected apps. Sign out there stops it at once.
For a machine with no browser, or a script, use a personal token from AI Integrations. It starts with vxm_ and is shown only once, so copy it when you create it.
Run this in your terminal, with your token in place of <your token>:
claude mcp add --transport http voxmin https://api.voxmin.com/auth/mcp \
--header "Authorization: Bearer <your token>"
That adds Voxmin for you in the current project. To have it in every project, add --scope user:
claude mcp add --transport http --scope user voxmin https://api.voxmin.com/auth/mcp \
--header "Authorization: Bearer <your token>"
--scope project writes the server into .mcp.json at the root of the repository, which is meant to be committed. Never put a token in that file. Claude Code expands environment variables in .mcp.json, so each person keeps their own token in VOXMIN_TOKEN:
{
"mcpServers": {
"voxmin": {
"type": "http",
"url": "https://api.voxmin.com/auth/mcp",
"headers": {
"Authorization": "Bearer ${VOXMIN_TOKEN}"
}
}
}
}
export VOXMIN_TOKEN="<your token>"
claude mcp list. Voxmin should show as connected./mcp lists the server and how many tools it has.get_account and answers with your credits.Then try something real — "Make a square picture of a lighthouse at dawn and give me the link" — and Claude Code will tell you the price before it spends.
| What you see | Why | What to do |
|---|---|---|
401 Unauthorized, or "failed to connect" | The token is wrong, revoked or expired, or the account is suspended or deleted | Make a new token on AI Integrations, then claude mcp remove voxmin and add it again |
| "Daily credit cap reached" | Today's spend through this token would pass the cap you set on it | Wait until midnight UTC, or make a token with a higher cap |
| "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 through this token | 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 |

“Documentation covers edge cases well. The "numPasses" parameter documentation alone saved us hours of trial and error.”
