Free tier	One price of USD 20 per seat per month for 2 vCPU (1 guaranteed, the second when the host has spare capacity), 4 GiB RAM, a 20 GB disk, 100 GB of egress and a public IPv4, with no per-second meter and no overage. Each seat is one box with SSH, an MCP server inside the box and a dashboard. Idle boxes sleep, which is how the flat price is possible. unit hours; metered on wall-clock; none

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.
Reliability	no reliability event recorded
Notes	Recorded as paid-only rather than trial-only because no free lane was found on the pages reached. The hosted cloud console at cloud.containarium.dev answered with a login wall behind scripts (broker read reported login-wall, status 409), so a trial, if one exists, is invisible without an account; that is the open question and an account is what would settle it. 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.
