rachio-mcp

An unofficial MCP server for Rachio sprinkler controllers that uses a reverse-engineered gRPC API to provide full control capabilities beyond the read-only public API. It allows agents to list devices and zones, manage schedules (create, update, delete), and perform live watering controls such as starting/stopping zones and setting rain delays.
