Check Existing Issues

  • I have searched for any existing and/or related issues.
  • I have searched for any existing and/or related discussions.
  • I have also searched in the CLOSED issues AND CLOSED discussions and found no related items (your issue might already be addressed on the development branch!).
  • I am using the latest version of Open WebUI.

Installation Method

Docker

Open WebUI Version

V08.12

Ollama Version (if applicable)

0.21.0

Operating System

debian

Browser (if applicable)

Chrome

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both Open WebUI and Ollama.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have provided every relevant configuration, setting, and environment variable used in my setup.
  • I have clearly listed every relevant configuration, custom setting, environment variable, and command-line option that influences my setup (such as Docker Compose overrides, .env values, browser settings, authentication configurations, etc).
  • I have documented step-by-step reproduction instructions that are precise, sequential, and leave nothing to interpretation. My steps:
  • Start with the initial platform/version/OS and dependencies used,
  • Specify exact install/launch/configure commands,
  • List URLs visited, user input (incl. example values/emails/passwords if needed),
  • Describe all options and toggles enabled or changed,
  • Include any files or environmental changes,
  • Identify the expected and actual result at each stage,
  • Ensure any reasonably skilled user can follow and hit the same issue.

Expected Behavior

I'm trying to integrate the Home Assistant MCP server via the OpenWebUI interface. /admin/settings/integrations
URL: http://xx.xx.xx:8123/api/mcp
Authentication:
Bearer: xxxxxxxxxxxxxxxxxxx
I expect a successful connection test and a tool selection in the chat

Actual Behavior

The connection test returns no result, but the following logs appear in the Docker container:

Exception in ASGI application

Steps to Reproduce

Config:

[
    {
        "type": "mcp",
        "url": "http://xx.xx.xx:8123/api/mcp",

I am seeing similar behavior for all remote MCP servers in Open WebUI v0.9.0 and above.

Same ASGI Exception error messge as reported above.

Reverting Open WebUI to v0.8.12 restores the remote MCP server functionality for me.

I'm using the latest Docker image from: ghcr.io/open-webui/open-webui:main
The "About" section shows Open WebUI version v0.8.12 (latest)

changed from main to Tag [v0.8.12] and now the connection test works
