| Composes with | A box that keeps its filesystem and runs an MCP server is the piece a stateless sandbox lacks: an agent reconnects over SSH or HTTPS by hostname and finds its tools and caches still installed, so the setup cost is paid once a month rather than once a run. |

| Notes | The core is Apache 2.0 and self-hostable, which is not a price for a user but does mean the same box can run on any rented VM. At USD 20 for 1 guaranteed vCPU and 4 GiB this is the cheapest flat-rate agent box found after RemoteHost's per-hour arithmetic. |
