Hey folks,

I recently hacked together RunJS using this csharp-sdk package.

RunJS is a .NET MCP server that uses Jint to execute LLM generated JavaScript. It includes a fetch analogue to LLMs can generate JavaScript that incorporates fetch.

To hide API keys, it also includes a secret manager that hands the calling side a "secret ID" which can be exchanged later for the actual secret when making the API call.

Check it out!
