Check Existing Issues

  • I have searched the existing issues and discussions.
  • I am using the latest version of mcpo.

mcpo Version

0.0.14

Open WebUI Version (if applicable)

v0.6.9

Operating System

Docker on GCP machines

Browser (if applicable)

No response

Confirmation

  • I have read and followed all instructions in README.md.
  • I am using the latest version of both MCPO and Open WebUI.
  • I have included the browser console logs.
  • I have included the Docker container logs.
  • I have listed steps to reproduce the bug in detail.

Expected Behavior

Trying to wire this up with gemini 2.5 pro. I've enabled native calling there and hooked in my mcp, but I dont see any way of debugging what payload actually gets sent to gemini? What tools is it attempting to run?

My assumption is that it's some field that gemini doesn't like, but that's very hard to debug at the moment.

In the ui if I go in and query the url for the tool server I can load the definition for the tool just fine.

Actual Behavior

400: Open WebUI: Server Connection Error

Steps to Reproduce

  1. Enable gemini 2.5 pro with native function calling mode and link in an mcp
