I'm KV, an upcoming grad, previously built rl envs + infra at verita-ai.com, hud.ai (YC W25), mecha.so and fileago.com

And built some projects like: sandbox for agents with firecracker and rust [ https://github.com/vrn21/bouvet ] ; a key value store in rust[ https://github.com/hrefto/shorterdb ]; a serverless FaaS platform with WASM and rust [ https://github.com/orbit-serverless/server ]; a postgres extension with pgrx for full text search using tantivy, bm25, rust [ https://github.com/vrn21/pdb ]

I'm KV, upcoming grad, previously interned at 3 startups [1x YC], where most of my work has revolved around Systems [Rust, Python, Docker, Linux]; You could see more info at my resume: [vrn21.com/resume]

from a utilitarian perspective, can we swap this instead of a e2b or some other provider? since this doesnt require n number of micrvovm kernals and rootfs hanging round?

so user gets all of the dependencies and apps in userspace to run as well? but each of the command runs in its own more secure shell of some sorts?

no on noticing it?

link not found btw

lol thanks for the compliments, generated both the testimonials after giving the mcp server to both opus and gemini and asked their feedback on it.

it is supposed to be directly used by agents, so they are kind of my end users, hence it made sense to get their testimonials :)

my ideal scenario is a cloud web model getting access to a sandbox to run commands and read/write to files. but yeah it could be used as an alternative to bash and read write tools.

I did not get your second question exactly, but yeah microvms can be considered one of the secure ways to run your agent

every syscall on containers run on the kernal with full privelages, so if needed one can break out of the container and get access to the host

Luis wrote an excellent blog about it btw: https://www.luiscardoso.dev/blog/sandboxes-for-ai

yes this is pretty busy market, but it is just pure infra/OS problem and many of it has already been solved in the past decades, right now its just who can fit everything together fastest

Thanks for the compliments! I can't really say that it has a unique differentiator between all the other sandboxes out in the market, this was supposed to be a poc version on how i could be building a sandbox for agents, this had been haunting me since a few months, tried out what could happen!

the actual sandboxes in the market are doing a lot of work in optimizing the system end to end, and most of it is pretty hard. this project just scratches the surface

hi, you could find my socials at https://vrn21.com, feel free to dm :)

using sandboxes makes a lot of sense now a days, but this is nowhere near the prod sandboxes the market has, they have a lot of work and optimizations going on! but yeah its little fun side project! thanks for the compliments :)

tbh, this is kind of a gray area, i should have thought little bit more on how it should have been architectured,

for me this was the ideal scenario: a cloud model on web with its own sandbox (something like claude with read/write to files and run commands)

i dont really think this could be considered as a fox guarding the hen house, its not that ai wants to infect your computer with its commands, if ai is provided the mcp server, it will it instead of using the tools like bash in most cases [if in a local setup]. I feel its more of a lumberjack guarding his weapons.

yes, it is supposed to be hosted on bare metal linux machines; anyone on any machine can use it as a sandbox after adding the mcp server to the client

i think https://github.com/trycua/cua has some sort of it working
