Connect another AI app

Other AI apps can use Vessero too, if they take a remote MCP server over Streamable HTTP. They connect by signing in (OAuth), or with an API key sent in a header. In Connected apps, the same steps open one at a time, with the address to copy, and the last one tells you when your app is in.

Connect your app

1. Give it the address. In your app's settings, add a remote MCP server.
2. Name it Vessero and give it the address https://vessero.com/mcp. Pick Streamable HTTP if it asks how to connect.
3. Sign in, or use a key. If your app offers to sign in, use that: Vessero's page opens, and you press Allow.
4. If it can't sign in, make it a key. In Connected apps, under Connect another app, press Another app, and at step 2 press Use a key instead.
5. Name the key, choose what it can do and, if you like, give it a daily cap. Press Make the key.
6. Give your app the header the page shows, Authorization: Bearer vsk_… with your key in place of vsk_…. It sends it with every call.
7. Check it works. In a chat in your app, ask: "Use Vessero to show my credit balance."

What your app needs to know

• The address is https://vessero.com/mcp, over Streamable HTTP. Paste it exactly: with www. in front or a slash at the end, the sign-in can fail.
• Signing in is OAuth. The app registers itself with Vessero as it signs in, so there's no client ID or secret to type in.
• A key goes in the Authorization header, after Bearer and a space.

If your app doesn't say where it takes a remote MCP server, its own help will.
