[Bug]: Breaking change in LiteLLM 1.96+: managed MCP OAuth2 flow opens LiteLLM UI instead of the vendor authorization page
![[Bug]: Breaking change in LiteLLM 1.96+: managed MCP OAuth2 flow opens LiteLLM UI instead of the vendor authorization page](https://www.chat-gpts.plus/wp-content/uploads/2026/09/39665-f15a8979-768x403.jpg)
LiteLLM 1.96+ 引入的 is_gateway_managed_oauth2 属性将命名 MCP 服务器错误归类为聚合网关 DCR 流,导致 OAuth 授权重定向到 LiteLLM 登录 UI 而非厂商授权页。优先检查 discoverable_endpoints.py 中的响应构建逻辑
