CLI

mcidrac [--transport {http,stdio,sse}] [--host HOST] [--port PORT]
        [--path PATH] [--config FILE] [--check]

Flag	Default	Purpose
--transport	http	http = streamable-HTTP (network clients), stdio = spawned per session by an MCP client, sse = legacy SSE.
--host	127.0.0.1	HTTP bind address. Bind wider only on trusted networks — there is no auth layer.
--port	7903	HTTP bind port.
--path	/mcp	HTTP path prefix.
--config	search order	Explicit registry path, overriding the search order.
--check	—	Load and validate the registry, print the banner, exit.

Exit codes

Code	Meaning
0	Clean start / --check passed
2	Registry config error (message on stderr says exactly what)

Startup behavior

The registry is loaded before the server starts serving, so a bad config fails fast at launch rather than on the first tool call. The banner (stderr) lists the transport, endpoint, and configured iDRAC names:

mcidrac v2026.8.10
  transport: http @ http://127.0.0.1:7903/mcp
  iDRACs:    2 configured -> r740-lab, r650-prod

Typical invocations

mcidrac --check                          # validate config
mcidrac                                  # HTTP on 127.0.0.1:7903/mcp
mcidrac --transport stdio                # for MCP client spawning
MCIDRAC_CONFIG=./lab.toml mcidrac --check
