MacPherson will spend a week at the finals as part of his UEFA Pro Coaching Licence which he hopes to complete by September.
The Buddies boss, who has a full team of players coming to the end of their contracts next month, will begin his annual search for fresh blood as soon as the present Clydesdale Bank Premier League campaign ends.
However, he accepts that he will not be making offers to any players appearing at the Euro finals.
"I'm going to the European Championships with Jim Fleeting from the SFA," MacPherson said.
"There are two groups of eight on the course, one going the first week and one going the second week.
"I have been doing the course for a couple of years and this is the last part of it, although it will not finish until September.
"Funnily enough, I won't be looking to scout any players at the European Championships.
"Those players don't come into our thinking. I don't know what my budget will be. I never ask but I know what I can get in terms of wages.
"It will most likely be players from the First Division in Scotland and lower leagues and even non-league in England.
"The recruitment of players is the hardest part of the job.
"It doesn't matter if it's the top clubs looking for the top players or not, it's always hard to improve your squad.
"You identify players who you can hopefully entice to the club but sometimes it's not about money and we've found that to be the case in the past."
