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

v0.8.8

Ollama Version (if applicable)

No response

Operating System

CentOS Stream 9

Browser (if applicable)

No response

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 go to Workspace > Tools > Import from URL, specify an MCPO-derived URL (http://localhost:8000/playwright/openapi.json), it fetches the JSON, I click save, and it saves.

Actual Behavior

When I click Save, I see an error toast saying "name 'true' is not defined" in the browser.

Steps to Reproduce

  1. Clean CentOS Stream 9 build
  2. Set up docker install of open-webui
  3. Set up mcpo with any tool server(s) defined
  4. Go to Workspace in left nav menu
  5. Go to Tools along top menu
  6. Click New tool
  7. Click Import from URL
  8. Enter http://localhost:8000/tool/openapi.json
  9. Click Save

Originally created by @ayan4m1 on GitHub (Mar 3, 2026). Original GitHub issue: https://github.com/open-webui/open-webui/issues/22190 ### Check Existing Issues - [x] I have searched for any existing and/or related issues. - [x] I have searched for any existing and/or related discussions. - [x] 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!). - [x] I am using the latest version of Open WebUI. ### Installation Method Docker ### Open WebUI Version v0.8.8 ### Ollama Version (if applicable) _No response_ ### Operating System CentOS Stream 9 ### Browser (if applicable) _No response_ ### Confirmation - [x] I have read and followed all instructions in `README.md`. - [x] I am using the latest version of **both** Open WebUI and Ollama. - [x] I have included the browser console logs. - [x] I have included the Docker container logs. - [x] I have **provided every relevant configuration, setting, and environment variable used in my setup.** - [x] 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). - [x] 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 go to Workspace > Tools > Import from URL, specify an MCPO-derived URL (http://localhost:8000/playwright/openapi.json), it fetches the JSON, I click save, and it saves. ### Actual Behavior When I click Save, I see an error toast saying "name 'true' is not defined" in the browser. ### Steps to Reproduce 1. Clean CentOS Stream 9 build 2. Set up docker install of open-webui 3. Set up mcpo with any tool server(s) defined 4. Go to Workspace in left nav menu 5. Go to Tools along top menu 6. Click New tool 7. Click Import from URL 8. Enter http://localhost:8000/tool/openapi.json 9. Click Save ### Logs & Screenshots Container log ``` ui-1 | 2026-03-03 18:05:06.005 | INFO | open_webui.utils.plugin:install_frontmatter_requirements:434 - No requirements found in frontmatter. ui-1 |

That is shockingly unhelpful.

That doesn't work either, I added it there to begin with but it doesn't show up as a checkable box for any of the models I have available. I see one of the two tool servers that I have added under Settings > Connections, the other one is missing

Guiding you to the docs which you refused to read before opening an ISSUE about how there is a BUG in Open WebUI is toxic? Aight got it.

You said you can't add mcpo tools to workspace - which is not intended to begin with.

In that sense I'd like to point you to the Code of Conduct which you violated repeatedly.

If a tool server is missing, your server probably can't connect to it properly.

And if you want to activate a tool server tool for a model you should enable it in the chat
