OpenAI compatible LLM endpoint?

[tftranslate]

I just discovered AnythingMCP as a potential MCP for my bank. This sounds great! Before venturing further, I have a question:
I see that for the (optional) AI-baed features you support OpenRouter, OpenAI and Anthropic.
I would much appreciate if you could add "OpenAI compatible" here, i.e. another environment variable setting where I can specify a different endpoint URL than the OpenAI default one (otherwise, the code logic is the same).
Reason: With the advent of platforms such as Strix Halo and DGX Spark, self-hosted models now are capable enough to run tasks similiar to the ones anythingmcp can use without the need for cloud services. In order to connect to a self-hosted llama.cpp, we need to be able to connect to an "OpenAI compatible" endpoint.
