A few weeks back, I actually started working on an MCP server that is designed to let the LLM generate and execute JavaScript in a safe, sandboxed C# runtime with Jint as the interpreter.
https://github.com/CharlieDigital/runjs
Lets the LLM safely generate and execute whatever code it needs. Bounded by statement count, memory limits, and runtime limits.
It has a built in secrets manager API (so generated code can make use of remote APIs) can, HTTP fetch analogue, JSONPath for JSON handling, and Polly for HTTP request resiliency.
I don't meant to throw shade on your toy, but trying to get a prediction model to use a language that actively hates developers is a real roll-the-dice outcome
Which language? C# or JS? OpenAI and Claude are quite good at JS. The runtime is C# to sandbox the execution so it is not being generated.
