CONF-004: Every result carries resultType

Severity	Applies to	Spec section
error	modern era, stdio, http	2026-07-28/basic/index#result-responses

Calls server/discover and, if tools are declared, tools/list. Every result MUST include a resultType string; values outside the core set (complete, input_required) are allowed only when the server advertises extensions.

From the command line: mcpprobe checks explain CONF-004. To leave it out of a run, add "CONF-004" to [checks] disable in mcpprobe.toml; to change how much it counts, use severity_overrides.
