Following command will give AST info, but not JSON format.

soar -query file.sql -report-type ast
soar -query file.sql -report-type tiast

AST support JSON format may be more useful for other program.

Add -report-type=ast-json for vitess parser or -report-type=tiast-json for pingcap parser

Complicate SQL print all AST info will give a large JSON. We should consider more cases for this issue.
