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 am trying to ascertain whether the API allows the use of web searches and MCP tools in the same way that you can launch queries through API calls. The docs are silent on external connections and for the life of me I can't get Swagger API docs to work on my docker container. I got really excited about Claude giving me an API call that did it but I think it just hallucinated the ability as it doesn't work (but I can fix as I can't find a reference to fix it with). Apologies if issues with docs shouldn't be raised this way, or indeed I just haven't read the right bit)

Actual Behavior

Docs detail or exclude external connections via API. I had expected it to be exposed in the same kind of way that knowledge and files are exposed.

Adding to this, I also just discovered the tools and functions area of the openwebui site and that opened my eyes to capability extension. This makes me stand by the fact that openwebui is the best front end to self hosting (or even cloud hosted) by miles, but it's just a pity to then have to replicate this capability in a second platform like N8n for other tools (like plugins into MS Word) that need to use more than just plain query/response, and if you make it in API it kind of defeats the point of openwebui running alongside! A full API access to give parity to the UI would be amazing
