Claude (web, desktop, mobile)

Add vincevangen to Claude as a custom connector. You sign in with your vincevangen account; no API key.

Claude opens with vincevangen and its settings filled in. Leave them as they are and click Continue → Add → Connect, then sign in or sign up for your free vincevangen account. No API key needed.

Add the connector once on claude.ai and it works in Claude on the web, the desktop app and the mobile apps. It also shows up in Claude Code when you sign in to Claude Code with the same Claude account.

If you don't have a vincevangen account yet, the first sign-in creates one with the free sign-up credits. Sign in with the same email you use on the website and the connector uses that account.

1. Add the connector

Click Add to Claude above. Claude opens with vincevangen and its settings filled in. Leave them as they are and click Continue → Add → Connect. Then sign in or sign up for your free vincevangen account.

Or add it by hand:

In claude.ai, open Customize → Connectors.
Click + Add, then Add custom connector.
Name: vincevangen. URL:

https://api.vincevangen.com/mcp

Leave the advanced OAuth fields empty and click Add.
Click Connect and sign in with your vincevangen account. Claude keeps the session, so you sign in once per Claude account.

2. Ask for an asset

Ask in any chat:

Make a product photo of a ceramic coffee dripper on a walnut counter, soft window light from the right.

A brief like that gets one final. If you want to choose, add "show me a few options first": Claude drafts four on the cheapest tier, shows you the sheet and finishes the one you pick at full quality. Drafts are cheap; the finish costs more than a plain final, so they pay off when you would otherwise want two or more finished versions.

Calls are charged to the vincevangen account you signed in with, in credits, exactly as with an API key.

Your own photos

Attach a photo to the chat and ask Claude to edit it. To let Claude send the photo straight to vincevangen, allow its sandbox to reach the server once:

Open Settings → Capabilities.
Turn on Code execution and file creation and Allow network egress.
Under Domain allowlist, add api.vincevangen.com to the additional allowed domains.

Without this, Claude gives you a one-time upload link instead: open it, pick the photo and Claude carries on. On Team and Enterprise an organisation owner sets these under Organization settings → Capabilities.

Fewer permission prompts

Claude asks before each connector tool call. To stop the prompts, open Customize → Connectors → vincevangen and set the tools to Always allow, or click Always allow on the prompt in a chat. Claude still gets a quote before every paid call, and a call that would cost more than your balance is refused before it runs. On Team and Enterprise an organisation owner sets tool permissions for everyone.

Plans and teams

Custom connectors work on every Claude plan. The Free plan allows one custom connector.
On Team and Enterprise, an organisation owner adds the connector first, under Organization settings → Connectors → Add → Custom → Web, with the URL above, or with this link, which opens that dialog filled in. Members can't add custom connectors, so Add to Claude opens no dialog for them. Members then open Customize → Connectors and click Connect. Each member signs in with their own vincevangen account.
Add the connector on the web. The desktop and mobile apps use the connectors on your Claude account.

Claude Code

If you use Claude Code signed in with your Claude subscription, the connector is already there: /mcp lists it as claude.ai vincevangen. Claude Code running on an Anthropic API key doesn't load claude.ai connectors; use the Claude Code quickstart instead.

Troubleshooting

Symptom	Cause
"You already have an account with this email address" or "An account already uses this inbox"	Your inbox already has an account under another spelling of the address. Remove the connector, add it again and sign in with the address the message shows.
`email_unverified` after signing in	You haven't entered the code from the sign-in email yet. Finish signing in, then reconnect.
`402 insufficient_credits`	Balance is below the estimate. Top up in the dashboard.
Claude keeps asking you to connect	Remove the connector in Customize → Connectors and add it again. Claude can't edit sign-in settings of a connector once added.
The tools don't appear in a chat	Check that vincevangen is switched on in that chat's tools menu.
