Check Existing Issues

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

Problem Description

I'm trying to setup a tool server to connect to dbt's remote MCP server by following the instructions here:
https://docs.getdbt.com/docs/dbt-ai/setup-remote-mcp

From my understanding, they require custom headers to be configured in addition to the Bearer Token, but I cannot figure out a way to do this in OpenWebUI, and they do not support OAuth yet.
Is passing these custom headers supported already? If not would it be possible to add?

Desired Solution you'd like

Support for configuring custom headers when connecting to remote MCP servers. Thank you!

@tjbck does add the ability to pass dynamic values like chat_id or username?
