If they open it up, possibly. But honestly, building your own tools is _super_ easy with langchain.
- write a simple prompt that describes what the tool does, and
- provide it a python function to execute when the LLM decides that the question it's asked matches the tool description.
Open what up? The plugins are just a public manifest file pointing to an openapi spec. It's just a public formalised version of what langchain asks for.
