MySQL privilege needed to grant “SHOW INDEX” access

Question

I'd like a monitor user be able to (only) execute "SHOW INDEX" and "SHOW TABLES" on a certain database. What privileges should I GRANT this user?

I'd rather not open up for the user to be able to do SELECTs...

Answer 1

I believe SELECT is necessary for both of these commands. I suspect the only way to be absolutely certain is to test this performance.

Arthur Ogawa's comment reinforces my suspicion.
