Both involve the main character getting into another world.
Both main characters try to help the people of the village they end up in with building better tools and equipment to raise the quality of live of the people and the whole village. The newly introduced tools/inventions are there to be spread across the land to make life better in the whole country.
While Takarakuji de 40-oku Atattanda kedo Isekai ni Ijuusuru focuses on handmade items and tools or things you can buy in the "modern world", Magicraft Meister focuses on creating these tools with the magical ability of the main character.
