At the foundation of the Gaelic Athletic Association, MacCarthy was a District Inspector of the Royal Irish Constabulary based at Templemore, County Tipperary. He was coached by Cusack for an RIC cadetship examination in 1882, in which he took first place. In 1881, he joined Dublin University Football Club and was capped against Wales in 1882.
He also played soccer for Limavady Football Club when he was stationed in the town in 1889, captaining the club in 1889
He had a great love of the game of hurling, which he witnessed being played in his native village by the local enthusiasts who were later to form the Galtee Rovers Gaelic Athletic Association Hurling and Football club
He was a regular attender at matches in Croke Park to where he travelled from his home at Oakley Road in the Dublin suburb of Ranelagh.
Later in 1882, he was a member of the Dublin University team which won the Leinster Senior Cup, the inaugural year of this competition. Gaelic Athletic Association authorities have erected a commemorative gravestone at Deansgrange where it was unveiled on Wednesday, 18 November 2009, as part of the "Re-dedication of Founder"s Graves" programme to mark the 125th Anniversary of the founding of the Gaelic Athletic Association, and there have also been calls for more recognition of his contribution to the Gaelic Athletic Association.
Unlike, the other six founding members of the Gaelic Athletic Association, very little has been done to commemorate MacCarthy. The Garda Síochána and the Police Service of Northern Ireland have honoured McCarthy by presenting The Thomas Saint George MacCarthy Cup for competition by members of the Garda Gaelic Athletic Association (Garda Thirds) and the Police Service of Northern Ireland.
