What is Maker MKR?

Could you please elaborate on what Maker MKR exactly is? I've heard it mentioned in the crypto community, but I'm still not quite clear on its functionality and significance within the blockchain ecosystem. Is it a token? A platform? Or perhaps something else entirely? How does it fit into the larger scheme of decentralized finance? And what are some of the key features or benefits that make Maker MKR stand out from other projects in this space?
