The One Probe

The One Probe reveals details about the block you're looking at while you hold a probe in either hand, including its name, source mod and harvesting tool. You can also configure the information to stay visible. Available for Forge, NeoForge and Fabric on Minecraft 1.12.2–26.2, it must be installed on the server too.

Rent your own Minecraft server and install The One Probe with one click from the panel to bring probe-based block information into your shared world.
