Agreed that this is a huge limit. There's a lot of examples actually of "tool calling" but it's all bespoke code-it-yourself: very few of these systems have MCP integration.

I have a ton of respect for SGLang as a runtime. I'm hoping something can be done there. https://github.com/sgl-project/sglang/discussions/4461 . As noted in that thread, it is really great that Qwen3-Coder has a tool-parser built-in: hopefully can be some kind useful reference/start. https://huggingface.co/Qwen/Qwen3-Coder-480B-A35B-Instruct/b...
