This design choice reflects our architecture: Open WebUI is a **web-based, multi-tenant environment**, not a local desktop process. + +Browsers operate within strict **sandboxed and event-driven HTTP constraints**, making long-lived stdio or SSE connections difficult to maintain securely across users and sessions. + +If you need to bridge those other MCP transports, check out [**mcpo**](https://github.com/open-webui/mcpo) — an open-source proxy that translates **stdio or SSE-based MCP servers into OpenAPI-compatible endpoints**. It effectively lets you run traditional MCP tools inside Open WebUI without modifying their transport layer. **Is MCP considered stable here?** Supported and improving. The broader ecosystem is still evolving; expect occasional breaking changes.
