Check Existing Issues

I have searched for all existing open AND closed issues and discussions for similar requests. I have found none that is comparable to my request.

Verify Feature Scope

I have read through and understood the scope definition for feature requests in the Issues section. I believe my feature request meets the definition and belongs in the Issues section instead of the Discussions.

Problem Description

I am trying to register a new MCP server onto my open-webui instance. Rather than using dynamic registration, the remote server are providing the client ID and client secret in order to register/connect. However, the UI doesn't allow us to manually input the client ID. We can only register clients dynamically. For example, I am trying to setup HubSpot's MCP (Instructions here) on OWUI. I am unable to do so as they don't provide the registration endpoint but their instructions provide a client ID and secret for us to use.

Desired Solution you'd like

Reviewing the MCP spec and Hubspot's MCP, while not supporting dynamic client registration, they have provided alternative methods of granting us the client ID. The desired solution would be to input this information via the UI, API and/or Environment Variables

Alternatives Considered

Disable dynamic registration and allows the payload/body of the URL to be amended so that the user is able to pass in that information
