Iron Rain puts coding agents on your Mac—and in your pocket

Field notes

The product places supported command-line agents on a user's existing Mac filesystem, then mirrors sessions to native iPhone and iPad clients. Its control model is unusually concrete: a paused agent can request permission for a shell command, file write, or commit, and the user can allow or deny that exact call from a push notification. The page also describes provider switching, quota checks, cost budgets, a shared MCP registry, and a relay that forwards encrypted traffic rather than running the workload remotely.
