Wakeonlan MCP server

@cyanheads/wakeonlan-mcp-server Wake LAN machines with Wake-on-LAN magic packets from host profiles, then confirm they came up via MCP. STDIO or Streamable HTTP. 4 Tools

Overview

Wake-on-LAN for the machines on your local network, addressed by the aliases in your host profiles. Wake a sleeping desktop, GPU box, NAS, or lab machine, wait until it answers on a TCP port such as SSH, check whether a host is up without waking it, and work through a wake that didn't take. Runs as a stdio process or a local Streamable HTTP server on a machine attached to the same LAN as the hosts it wakes.

• alias (from wollisthosts, case-insensitive) plus optional waitfors, 0–55 seconds, default 30; 0 sends and returns without checking. Sends 3 packets 500 ms apart, probing the check port once before sending and every 2 s after the first packet
• state is alreadyawake, awake (with timetoanswerms, an upper bound at the 2 s poll interval), notreachable, or unverified (unverifiedreason: waitdisabled or noaddress); the last two carry a guidance next step
• Fails as unknownhost, offsegment (nothing sent: this machine has no interface on the host's subnet), retryable wakeinprogress (nothing sent: another call is already waking that host, and one wake per host runs at a time), or retryable socketerror, whose data carries the failed stage and packetssent
