We present a brief summary of the ISO survey of AGB stars in 8 populous intermediate age clusters of the Magellanic Clouds. Totally, more than 100 AGB and RGB stars were observed at 4.5, 6.7 and 12 micron. We introduce a new method to estimate effective temperatures of oxygen-rich AGB stars, and derive precise Mbol and Teff for a large population of AGB objects in both LMC and SMC. The derived stellar parameters are used to construct observed HR diagrams which are employed further to estimate cluster ages using the isochrone fitting. We show that proposed method gives a powerful tool to study AGB star populations within the Local Group galaxies, especially, when backed up with the observations from forthcoming mid-IR astronomical space facilities (ASTRO-F, SIRTF) and large ground-based telescopes (SUBARU, VLT, etc.).
