Did you ever have the problem where you needed to interact with multiple sides of a block?
Well, those days are over now!
With the Capability Proxy, you can extend the capabilities (or block APIs in Fabric) of one side of a target block to five additional sides.
As of version 2.1.0, an Entity Capability Proxy and Item Capability Proxy can be used to interact with entities and items via blocks! More information hereafter.
Unable to interact with certain blocks such as the Composter? Try installing Common Capabilities, which adds capabilities to blocks that have none by default yet.
Capability Proxy



Regular proxies can communicate with their neighbours, while ranged proxies have a range of 16 blocks (configurable).

The regular proxies can be crafted like this:

The ranged proxies can be crafted like this:

Point the proxy towards a block that has capabilities, and all capabilities will be accessible from the proxy block.
Any kind of capability will work, such as items, fluids, energy, ...
Even block interactions will be forwarded, such as opening GUI's.

When no valid target block is present, the block will be in an inactive-state.

As many as five additional sides become available.

And if five wouldn't be enough, you can chain proxies to have even more available sides.

Energy proxy:

Integrated Dynamics network(capability-based) proxy:

Entity Capability Proxy
When entities have capabilities, this block allows you to interact with them as if they were a block.
The following examples show how to pipe items into a dropped Shulker Box. (This requires Common Capabilities to be installed)


Item Capability Proxy
When an item is inserted in this block, you can interact with the items as if they were this block. In this example, the proxy contains a tank, and its fluids are piped out into the world using Integrated Tunnels.

You can only pipe in/out different proxied items via the indicated side. (In this example, the bottom side)

This mod collects anonymized startup data, this can be disabled in the config file and adheres to Minecraft's snooper settings.
