The AGILE satellite discovered the transient source AGL J2241+4454 in 2010which triggered the study of the associated field allowing for the discovery ofthe first Be/black hole binary system: MWC 656. This binary was suggested to bethe counterpart of AGL J2241+4454, but this is still not a firm association. Inthis work we explore the archival AGILE and Fermi/LAT data in order to findmore transient events originating in the field of AGL J2241+4454 and addressthe possibility to link them to the accretion/ejection processes of MWC 656. Wefound a total of 9 other transient events with AGILE compatible with theposition of AGL J2241+4454, besides the one from 2010. We folded this eventswith the period of the binary system and we did not find significant resultsthat allow us to associate the gamma-ray activity to any particular orbitalphase. By stacking the 10 transient events we obtained a spectrum that extendsbetween 100 MeV and 1 GeV, and we fitted it with a power law with photon index{\Gamma} = 2.3 +/- 0.2. We searched into the Fermi /LAT data in order tocomplement the gamma-ray information provided by AGILE but no significantresults arose. In order to investigate this apparent contradiction between thetwo gamma-ray telescopes, we studied the exposure of the field of AGLJ2241+4454 in both instruments finding significant differences. In particular,AGILE exposed for longer time and at lower off-axis angle distance the field ofAGL J2241+4454. This fact, together with the energy dependent sensitivity ofboth instruments, and the soft spectrum found in the stacking analysis, mightexplain why AGILE observed the transient events not seen by Fermi/LAT.
