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
Custom workspace models configured with tools should work the same in channel messages; but the tools definitions are not included when sent to the chat completions API.
Include the tools for channel messages when sending to the chat completions API like how they were sent in normal chat messages.
E.g. The tools definition are sent in the chat completions API in a normal chat message
{"model":"gpt-4.1-mini",**"tools":[{"type":"function","function":{"name":"aria_query_database","parameters":{"type":"object","required":["query"],"properties":{"query":{"type":"string","examples":["List all missions completed.","Why did the mission tasks fail?"],"description":"Decomposed single query from user's queries"},...#truncatedforbrevity]**,"stream":true,"messages":[{"role":"system","content":"You are a detailed and helpful security AI assistant that helps draws on tools to create reports, conduct data analysis and troubleshooting. You have tools to retrieve more information about the robot mission, alerts event logs from the query_database tool."},{"role":"user","content":"for my robot id 22, are there any missions that require intervention this week?"}]}
Actual Behavior
Context
I was trying out the channels feature to chat with my custom model that i have added an MCP tool server with it to chat with my own data. The model successfully calls the tool in normal chat because the tools were included in the chat completions API and open web ui handles the flow of getting the tool arguments, calling the tool, and generating the answer. This should be the same for messages sent in channel messages for custom models.
E.g. The logs from LiteLLM shows that the tools argument are not present in the chat completions API which probably caused the model to not call the tools.
{"model":"gpt-4.1-mini",**#`tools`shouldbepresentheretoowheniamusingmycustommodel**"stream":false,"messages":[{"role":"system","content":"You are a detailed and helpful security AI assistant that helps draws on tools to create reports, conduct data analysis and troubleshooting.

Check the MCP tool to add the tool to the model by default
Chat with the new model in the Channels
Observe the model does not call the tool (because the tools were not included in the chat completions API)

### Steps to Reproduce
1. Install Docker
2. Start open web ui using docker
3. Add a MCP tool (Admin panel > Settings > External Tools )
4. Create a new model (Workspace > New model)
5. Check the MCP tool to add the tool to the model by default
6. Chat with the new model in the Channels
7. Observe the model does not call the tool (because the tools were not included in the chat completions API)
