# MCP Connect: Authorization Not Received

> The connection was completed before the OAuth callback delivered the authorization code.

**HTTP status:** 400

## Error message

```
The authorization code has not arrived yet. Finish the consent step, or start the connection again.
```

## When this error occurs

The authorization flow exists and belongs to you, but no authorization code has been parked on it yet. The external
authorization server redirects the user's browser to `GET /mcp-connections/callback` with the code, and that request is
what stores it. Completing before the callback has arrived — because the consent screen is still open, or the user closed
it without approving — has nothing to exchange.

## How to fix

Finish the consent step at the external authorization server, then complete again. If the consent screen was dismissed,
call `POST /mcp-connections` for a fresh authorize URL and start over; authorization flows are short-lived, so a stale
one expires rather than waiting indefinitely.
