Hi Vercel team,

We’re building Dalla AI (https://dallaai.com), a bilingual Arabic/English AI assistant for businesses in Qatar and the Gulf. Our users connect their own tools to Dalla over MCP, and many of them deploy on Vercel, so we’d like them to be able to connect Vercel MCP.

Dynamic client registration at https://api.vercel.com/login/oauth/register currently fails with: invalid_redirect_uri: The provided redirect URIs are not approved for use by this authorization server.

Could you please allowlist our redirect URIs (or issue us an approved MCP client_id)?

Production: https://dallaai.com/api/connectors/callback Staging: https://dalla-ai-qa.vercel.app/api/connectors/callback

How our client works:

Authorization code flow with PKCE (S256), public client (token_endpoint_auth_method: none), scope openid, refresh tokens for long-lived connections Each user signs in and approves the connection themselves; Dalla only acts with that user’s own access Tokens are never stored in our database. They’re kept encrypted in a per-user credential vault and injected server-side only when the user’s agent calls the MCP server Every tool call that changes something asks the user to approve it in the chat (Allow once / Always allow / Deny) before it runs

We’re also hosted on Vercel ourselves. Happy to provide anything else you need. Thanks!
