Agar was the son of James Agar, of Ringwood, County Kilkenny, by the Honourable Rebecca Flower, daughter of William Flower, 1st Baron Castle Durrow. Ellis Bermingham, Countess of Brandon, was his aunt. His father was killed in a duel with Henry Flood in 1769. He was educated at Eton and Trinity Hall, Cambridge.
Agar was returned to the Irish House of Commons for Callan in 1776, a seat he held until 1790, and was admitted to the Irish Privy Council in 1789. In 1790 he was elevated to the Peerage of Ireland as Baron Callan, of Callan in the County of Kilkenny. In 1801 he was elected as one of the original 28 Irish Representative peers to sit in the British House of Lords.
Lord Callan never married and the title became extinct on his death in October 1815, aged 63.
