Thanks :) It may sound insane but we convert actions to Python functions then ask the LLM to write a python script that actually runs in IronPython inside the game. Then we have a visual Behavior Tree system to let our designer define the actions. So yeah, they got a bunch of general actions like walk, talk, follow, interact etc.

PS: I think MCP/Tool Calls are a boondoggle and LLMs yearn to just run code. It's crazy how much better this works than JSON schema etc.
