Could you build this?
Partial Wrapping container APIs into an MCP server is straightforward, but securely isolating multi-tenant arbitrary code execution against kernel escapes requires deep systems security engineering.
What it would actually take: The system requires an orchestration daemon interfacing with lightweight virtualization or isolation technologies like Firecracker microVMs, gVisor, or hardened Linux namespaces (cgroups v2, seccomp-bpf, Landlock). The MCP layer handles agent commands, while the sandbox core must enforce strict network filtering, storage quotas, ephemeral disk teardown, and kernel attack surface reduction to safely run untrusted LLM-generated code.
