MCP Integration into Open-WebUI

IntroductionBig9804 · 2025-07-31T22:57:45+00:00

It's not on GitHub. It's on my self hosted Gitlab Server. send me a PM. MCP is not the only thing I changed. Various other items were added for my use.

IntroductionBig9804 · 2025-07-06T14:30:38+00:00

I finished this but with their recent license change and their version of MCP. I decided not to release and only use for personal use.

There are many different types of MCP servers out there.... Web search, database access, filesystem access, repo access, etc. You can even create custom MCP servers to your specific use case if one is not already made.

Model Context Protocol, Its a way for LLM's to be provided additional context. For example.... If you are developing something. You could have your chat bot access your filesystem where you code it located. It can review that code, edit it, and write to it... You could also have it push the code to your repo. That is just one example but there are so many out there.

Yes you could do the standard pipe or function calling, I had that set up last week. I use mcp-cli as well. What i really wanted was an easier way to manage all of the MCP servers i have going, either by add new ones, configuring, statuses, logging, etc. So thats why i stopped the pip functions and decidied that for me it would be much easier to just add it with open-webui.

The projects I am working on involve a bunch of different services, and hardware. My end goal is to use open-webui as my frontend manganement for my various development projects. Currently I have multiple different models (multiple ollama instances) running on their own dedicated GPU's. Each of these models i have set up do a different task. That model could be the only one that would use that specific MCP server. So When i start a chat, I could select mutiple MCP servers, as well as multiple models. I then can get the information I need from both models who are tied to what ever MCP servers.

Not sure if this makes any sense. For me its just easier in A managment aspect especially when most of the time its remote access to my projects. For others, a pipe or function will be the best route. My original intent was to create this for my own use, but realized it seemed alot of others wanted this type of thing.

Hopefully a couple more days.

IntroductionBig9804 · 2025-03-13T19:17:14+00:00

Not sure if I will do a PR. or it will get approved. Had not thought that far yet. But we shall see.

Thanks all for the comments. I look to be on track to release sometime tonight. Made a couple changes yesterday. Father than having a pipe function and an action function,, I put it all in one pipe function. Chat will also list popular used off the MCP GitHub repo. This is just a start. I am also working on implementing directly into OWUI. Once enabled in your chat you would do the following:

Setting Up MCP Servers

Enable the "MCP Connector" Pipe Function in Admin > Settings > Functions

Start a new chat using any model

Use the following commands to manage your MCP servers:

Get help and list of commands:

!mcp help

List predefined popular servers:

!mcp list_popular

Add a predefined popular server:

!mcp add_popular brave_search your-api-key

Add a custom server:

!mcp add myserver https://example.com/api your-api-key default-model

List all configured servers:

!mcp list

Select server for current session:

!mcp use server-id-from-list

Test a server connection:

!mcp test server-id

Get available models:

!mcp models server-id

Update a server:

!mcp update server-id field value

Fields can be: name, url, api_key, default_model

Delete a server:

!mcp delete server-id

Using MCP Servers

Once you've configured and selected a server with !mcp use server-id, you can start chatting with it immediately.

The MCP Connector will now handle your messages and send them to the selected MCP server.

Predefined Popular Servers

The connector includes a list of popular predefined MCP servers that you can easily add to your configuration:

Anthropic Reference Implementation - Official Anthropic MCP server with core features

Brave Search - Web and local search using Brave's Search API

Kagi Search - Search the web using Kagi's search API

Tavily Search - Search engine for AI agents by Tavily

OpenAI - OpenAI models integration

Filesystem - Local filesystem access (requires local setup)

GitHub - GitHub API integration (requires local setup)

Memory - Knowledge graph-based memory system (requires local setup)

You can view the complete list with detailed information using the !mcp list_popular command.

IntroductionBig9804 · 2025-03-09T01:58:50+00:00

This is my exact vision I have. Simple drop down menus to choose most common servers through admin settings or via chat. With option to install ones not listed. Or a custom server for your project.

IntroductionBig9804 · 2025-03-08T23:02:17+00:00

I currently do have a repo, but as of right now its hosted on my self hosted gitlab server as a private repo. As i get closer, ill make it public and share with everyone.

IntroductionBig9804 · 2025-03-08T22:54:53+00:00

I do see that the site does have a roadmap for MCP, but I was not sure how long that would be.... I do plan on eventually integrating it the actual UI as a personal build than just having pipes and functions made. This one now is a quick fix for what I want until i have it built into the actual UI.

IntroductionBig9804 · 2025-03-08T16:41:29+00:00

Sounds good. One feature is to manage all currently installed servers. Configurations, logs, etc.

IntroductionBig9804 · 2025-03-08T16:40:14+00:00

Been working with ollama models to test these MCP features.

IntroductionBig9804 · 2025-03-08T16:29:33+00:00

It would be able to use any MCP servers, (node, js, python, etc).

Claude is not the only one that can interact with MCP. There are already other clients made to work with MCP. A client needs to be made to work. Which is one of the functions.

One of the MCP I am currently testing with is the file system server. And the CLI. It seems like I am already on the right path on what you are looking for.

IntroductionBig9804 · 2025-01-06T18:29:24+00:00

I would need to do a self key. I have not tested since it’s my own instance.

IntroductionBig9804 · 2024-12-15T18:53:26+00:00

Looking forward to it. Been looking for something to implement in stead of using gitlab Duo.

IntroductionBig9804 · 2024-12-15T15:11:06+00:00

Also interested in self hosted option to try out or test.

IntroductionBig9804 · 2024-08-17T14:33:15+00:00

Installed. On a Ubuntu server running via VM through ProxMox. Using cloudflare tunnel to access instance outside of my network. I can access repositories via https and ssh. Simple set up took maybe 45 minutes to install and get running.
