Linktree Protected Resource

Register an OAuth client using Linktree's dynamic client registration endpoint at registration endpoint. The authorization server metadata at mcp.linktr.ee OAuth metadata shows token_endpoint_auth_methods_supported of none, client_secret_basic, and client_secret_post, so clients can be public or confidential depending on registration. Linktree's public developer page says access to APIs and SDKs is via its developer program and registration process on the developer program page and Developer Terms.
