He will aid boss Gordon Strachan and assistant Mark McGhee, after the departure of Andy Watson to a coaching role at a football school in Oman.
The Scots host Canada in a friendly on 22 March, four days before a vital 2018 World Cup qualifier against Slovenia.
"Tony is well respected within the game," said Strachan.
"I would like to thank [Dons manager] Derek McInnes and Aberdeen for allowing Tony to work with the Scotland backroom staff for these next two games."
Scotland are on four points after four matches and sit second bottom of World Cup qualifying Group F, four points adrift of second-placed Slovenia.

The scheme, introduced by mayor George Ferguson, aims to reduce commuter parking in the city.
Spike Island has become the 16th and final area to have parking restrictions introduced. The first one started in Kingsdown five years ago.
The policy has led to protests and vandalism of some parking machines. Some business owners have said it has damaged trade.
Mr Ferguson said: "The rollout has done what I hoped it would do, with most opposition fading once a scheme goes live, and the majority of residents and traders being pleasantly surprised.
"The feedback we're getting is that parking becomes much easier in the residents' parking zones."
He added that he would ask for the views of local councillors and neighbourhood partnerships before "reconsidering an extension to the scheme".

Five men were jailed in March for the £400,000 spree of raids and burglaries across the east of England.
About 140 officers from Bedfordshire, Cambridgeshire, Norfolk and two other units swooped on properties linked to the men on Wednesday.
It is thought the gang bought the goods with money from the robberies.
Police seized an Audi A5, a pick-up truck, a caravan, quad bikes and heavy machinery including diggers from properties in Wisbech in Cambridgeshire, Potton in Bedfordshire and Upwell in Norfolk.
Cannabis factories, with a combined street value between £18,000 and £54,000, were also discovered at the Potton and Upwell properties.
Police said the properties were connected to Joseph Upton, John Smith and Albert Smith.
Along with John Christopher Smith and Alfred Stanley, they were sentenced to 22 years for carrying out ram-raids at 12 banks in 2012 across Cambridgeshire, Lincolnshire, Norfolk and Suffolk.
They stole more than £300,000 from cash machines and cars and jewellery more than £100,000 during burglaries.
Damage caused in the ram-raids was estimated at costing about £250,000 to repair.
The courts will eventually decide what goods the gang accumulated from their wrong-doing and if they should be confiscated.
Det Ch Insp Chris Balmer, from the Eastern Region Special Operations Unit, which helped to serve the warrants, said the ram-raids affected "rural communities who lost their access to cash machines" and those who had "cars and machinery stolen by the gang in order to carry out the crimes".
"We will continue to pursue criminals after they have been convicted at court in order to strip them of any assets they may have gained," he said.

So when I suggest that new Welsh Secretary Alun Cairns will make history on Sunday, I'm not comparing his task to walking on the moon or finding a cure for the common cold.
Mr Cairns will become the first serving cabinet minister to run the London Marathon. Others have run it but either before or after their cabinet career.
Indeed, his recent promotion to the cabinet has had a major impact on his training for the 26.2 mile event, where the Vale of Glamorgan MP, the fastest in MP in last year's race, initially hoped to break 3 hours and 30 minutes.
"There's been a bit of a diversion over the last few weeks as well as an injury," he admitted. "So I'm not sure  I'll become the champion again of the MPs. And there is serious competition from Dan Jarvis, an ex-para, so I'm getting my excuses in early."
Mr Cairns is running his 5th marathon for two charities: Breast Cancer Now and The Brain Tumour Charity.
Aberdeen assistant manager Tony Docherty will join the Scotland national coaching team for the March fixtures against Canada and Slovenia.

We are so fond of the word 'historic' in Welsh politics that it is increasingly used to describe something vaguely interesting that hasn't happened before.
