EMI Structures
EMI Structures, a Fabric, Forge and NeoForge library, shows which structures generate each block and which materials they contain, inside EMI's recipe lookup.
What it does
Rather than keeping a fixed list of vanilla structures and their blocks, the mod reads structure definitions as the game runs, including those added by other mods and by datapacks. Standard data-driven jigsaw structures therefore appear without any manual compatibility work. Each discovered structure gets a single EMI recipe that holds its generation information, paginated by material, and a selected structure opens its own page.
Players look up a material in EMI as they would any recipe. A search for Mossy Cobblestone, for example, exposes a Structure Generation category listing the structures where that block was detected, along with the estimated quantity when one is available. Material amounts come from several lightweight analysis passes, and the mod generates sample real structures in the player's world to produce the displayed ranges, so the figures are estimates rather than guarantees for any single structure. The mod requires EMI and Fabric API, and it is licensed under the GNU General Public License v3.0 only, so the code is open source.
Key features
Structure Generation category
Each material gets a category in EMI that lists the structures where the block was found.
Runtime structure discovery
Structures are detected at runtime, so modded and datapack jigsaw structures are included without a manual list.
Generated material estimates
Quantities are estimated from sample structures in the player's world and shown as ranges.
Structure pages
Selecting a structure entry opens a page showing its biomes, placement information and materials.

How it compares
PF-EMI is a client-side only addon under the MIT License, with files for 1.21.2 – 1.21.11, so it targets a different version range. Fluid Tick Structure Processor is server-side only and licensed under the Apache License 2.0, with files for 1.20.1 – 1.21.1, and it changes structure generation rather than showing it in a lookup screen. EMI Loot is open source under the MIT License for 1.18.2 – 1.21.1 and runs on client and server.

Instead of maintaining a fixed list of vanilla structures or supported blocks, EMI Structures analyzes supported structure data from Minecraft, installed mods, and datapacks.
