Connect an AI app

You can use Vessero from an AI app such as Claude, ChatGPT, Cursor or Claude Code. Ask in your own words, and the app makes pictures, clips, voiceovers and more in your account, with your credits and at the studios' own prices. Apps connect over MCP, which is how AI apps plug into other services.

The address

Every app connects to the same address. It's in Connected apps in Settings, under Connect another app, with a copy button beside it:

https://vessero.com/mcp

Paste it exactly as it is. With www. in front or a slash at the end, some apps can't sign in.

Your app, one step at a time

Under Connect another app, press the app you use. Its steps open one at a time, beside the page on a computer and over it on a phone, with what to copy at the step that needs it. The last step waits for the app: it says the app is connected only once Vessero sees it come in, then gives you the first thing to ask.

The same steps are here for each app:

• Claude: claude.ai and the Claude desktop app, on every plan.
• ChatGPT: chatgpt.com, or the ChatGPT desktop app.
• Claude Code, in your terminal.
• Cursor, the code editor.
• VS Code with GitHub Copilot.
• Gemini CLI, in your terminal.
• Codex: the CLI, the IDE extension and the ChatGPT desktop app.
• Devin Desktop, formerly Windsurf.
• Perplexity, on its paid plans.
• Another app: any app that takes a remote MCP server.

Sign in, or use a key

Signing in is the way in for every app. The app sends you to a page on Vessero to allow it. If you're signed out, you sign in first and come back to it. That page shows:

• The app's name and where it asked from, such as claude.ai. The app gets a key to your account, never your password. If the page warns that the app answers on this computer, allow it only if you've just connected from an app on this computer.
• Who's signed in. If that isn't the account you want to connect, press Not you? to sign out, then sign in as the right one.
• What the app will be able to do: See your account (your credits, your work, the models and voices) and, if it asked for it, Make things and spend credits (every run is priced before it starts).
• Daily credit cap, optional, for an app that can spend: the most it may spend in a day. Leave it empty for no limit. You can change it later.
• Allow and Deny. Either way, you go back to the app.

Connecting has to finish within ten minutes. After that the page says the request has expired: start again from the app.

An API key is for a developer app on a computer with no browser to sign in with, such as a server you reach over SSH. Claude Code, Cursor, VS Code, Gemini CLI, Codex and Devin Desktop can take one, and so can most other apps that take a remote MCP server. Claude, ChatGPT and Perplexity connect by signing in.

At the step that adds Vessero to the app, press Use a key instead. Name the key, choose what it can do and, if you like, give it a daily cap, then press Make the key. The key is shown once, already in the command or settings that app needs.

You can also make a key on its own, with Create API key at the top of Connected apps:

1. Press Create API key.
2. Name it for where it lives, such as "Claude Code · MacBook", so you know which one to revoke later.
3. Choose what it can do. Every key can See your account. Tick Make things and spend credits for a key that makes things, or leave it off for one that only reads.
4. Set a daily credit cap, if you like. Empty means no limit.
5. Press Create key.

The key is shown once. Under Paste it into, pick Claude Code or Cursor and copy what it needs, with your key already in it. Copy key copies the key on its own. Once it's saved, press I've saved it.

From then on the list shows only the key's start and its last four characters, such as vsk_…a3F9, because we keep only a fingerprint of it. If you lose a key, revoke it and make another. You can keep up to 20 keys at once.

Anyone holding a key can see your account, and can spend your credits if the key can make things. Keep it out of shared files, screenshots and messages. A key also works in your own scripts.

The first thing to ask

Once it's connected, ask the app: "Use Vessero to show my credit balance." It's free and changes nothing, and the answer shows the app is reading your account. Then see What an AI app can do in your account.

Your connections

Connected apps lists every app and key that can use your account, the one used most recently first: what each can do (See, Make), its daily cap, and what it spent this week. Press one to change its cap or to disconnect it. See Credits, prices and daily caps with AI apps and Disconnect an app or revoke a key.
