Spin up Firecracker microVM dev environments with Boxcutter and coordinate agents via Tapegun host/guest plugins.

Overview

boxcutter is a plugin marketplace for the Build phase that provisions Firecracker dev microVMs and Tapegun messaging so Claude Code agents can work in isolated SSH environments.

What is this marketplace?

boxcutter v1.0.0: ephemeral dev VMs via Firecracker microVMs (~1s boot, LAN IPs, SSH)
tapegun-host v1.1.0: monitor VMs and send tasks from an external Claude manager
tapegun-guest v1.1.0: receive messages and tasks inside the VM from outside agents
Clean-room testing and isolated compute without polluting the host machine
Development-category marketplace with three complementary plugins
Marketplace bundles 3 plugins: boxcutter v1.0.0, tapegun-host v1.1.0, tapegun-guest v1.1.0
Documented ~1 second Firecracker microVM boot time in boxcutter description

Compatible agents: Claude Code, Codex, any compatible agent

Community signal: 1 GitHub stars.

What problem does it solve?

Local agent sessions share one messy host, so reproducing bugs, testing installers, or parallel agent work risks breaking your daily driver machine.

Who is it for?

Advanced solo builders and small teams running multi-agent or clean-room dev tests with Claude Code on real VMs.

Skip if: Beginners who only need in-repo edits on a single laptop without VM or SSH setup.

What do I get? / Deliverables

You launch disposable Boxcutter VMs in seconds, SSH in, and coordinate host and guest Claude instances through Tapegun for isolated agent tasks.

Running ephemeral dev microVM with SSH access
Tapegun-mediated task delivery between host and guest agents
Isolated environment for reproduce-and-fix or risky automation runs

BuildAgent skills & templates

Canonical shelf is build/agent-tooling because the stack exists to give coding agents isolated, SSH-ready machines on demand. boxcutter plus tapegun-host and tapegun-guest extend Claude Code with ephemeral VMs and cross-VM messaging—core agent infrastructure for builders.

How it compares

Infrastructure and VM orchestration plugins, not a design or SEO marketplace.
