MCP Doesn't Need 30 Tools: It Needs Code
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 sandboxed C# runtime with Jint.
https://github.com/CharlieDigital/runjs
It has a built in secrets manager API, HTTP fetch analogue, JSONPath for JSON handling, and Polly for HTTP request resiliency.

Ask HN: What Are You Working On? (June 2025)
https://github.com/CharlieDigital/runjs
I wrote an MCP server in C#/.NET that let's LLMs safely generate an run JavaScript using the Jint interpreter.
It includes a `fetch` analogue using `System.Net.HttpClient`, as well as `jsonpath-plus`, and a built-in secrets manager.
The prime use case is working with HTTP REST APIs with an LLM. With this, you can let users safely generate and execute JavaScript in a sandbox.

Remote MCP Support in Claude Code
I've been working on an MCP server[0] that let's LLMs safely and securely generate and execute JavaScript in a sandbox including using `fetch` to make API calls. It includes a built in secrets manager to prevent exposing secrets to the LLM.
I think this unlocks a lot of use cases that require code execution without compromising security. Biggest one is that you can now ask the LLM to make API calls securely because the JS is run in a C# interpreter with constraints for memory, time, and statement limits with hidden secrets (e.g. API keys).
The implementation is open source with sample client code in JS using Vercel AI SDK with a demo UI as well.
