e2b-shell

e2b-shell

Interactive shell over repos in a Mesa org running inside an E2B sandbox, written in TypeScript.

Spins up an E2B sandbox, installs Mesa, mounts your org's repos via FUSE, and drops you into a minimal shell. Commands execute inside the sandbox against the mounted filesystem.

Quick start

npm install

# Create a .env in this directory (gitignored)
cp .env.example .env

# Now populate your .env file with the required values

# Run
npm start

Creating E2B sandbox...
Mounting your-org...
Connected to your-org. Type "exit" or Ctrl+C to quit.

$ ls
repo-one  repo-two  repo-three
$ cd repo-one
$ ls
README.md  src/  package.json
$ exit
Cleaning up sandbox...
Bye!

How it works

1. Creates an E2B sandbox with a 1-hour timeout
2. Installs Mesa CLI and FUSE inside the sandbox
3. Starts the FUSE daemon (mesa mount --daemonize) with your org credentials
4. Drops you into a REPL rooted at the mounted org directory
