We operate [Individu](https://individu.ai), a personal AI agent platform. Users connect remote MCP servers (GitHub, Linear, Notion, etc.) through our integrations library so the agent can use their tools in chat and automations.
Connecting **Vercel MCP** (`https://mcp.vercel.com\`) fails at dynamic client registration with:
HTTP 400: {"error":"invalid_redirect_uri","error_description":"The provided redirect URIs are not approved for use by this authorization server."}
Our redirect URI is not on the Vercel MCP OAuth client allowlist. A self-created “Sign in with Vercel” dashboard app does not help — those tokens are only valid for the REST API, not `mcp.vercel.com`.
Please allowlist our redirect URI (or issue us an approved MCP `client_id`):
- **redirect_uri:** `https://individu.ai/api/integrations/oauth/callback\`
- **flow:** `authorization_code` + PKCE (S256), public client (`token_endpoint_auth_method: none`)
- **scope:** `openid offline_access`
- **resource:** `https://mcp.vercel.com/\`
Individu already connects many remote MCP providers via standard OAuth / DCR; Vercel’s approved-client allowlist is the only blocker. Happy to complete any client security review. Thank you!
