How to Call

unity-mcp-cli run-tool editor-application-set-state --input '{
  "isPlaying": false,
  "isPaused": false
}'

unity-mcp-cli run-tool editor-application-set-state --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool editor-application-set-state --input-file - <<'EOF'
{"param": "value"}
EOF
