How to Integrate Vertex AI Agent Builder with LibreChat via librechat.yaml?

[kshitizagarwal-dev]

Hi everyone,

I have a Vertex AI Agent Builder app, and I’m wondering how I can integrate it into LibreChat using the librechat.yaml configuration file. I don’t want to create plugins, agents, or use the "Add Actions" feature—just a direct integration via the config.

If this is possible, where would the integrated agent appear in the LibreChat UI? Would it be listed as a model option, or somewhere else?

I’d appreciate any guidance or examples from those who have set up similar integrations.

Thanks!
