How can I use CanPlaceOn and CanDestroy in Bedrock Edition?

Java Edition has the CanPlaceOn and CanDestroy NBT tags, which are used to restrict the blocks an item can be placed on and destroy respectively (in adventure mode). For example, the following commands give the player a stone block that can only be placed on grass and dirt, and a netherite axe that can only destroy pumpkins:

give @s stone{CanPlaceOn:["minecraft:grass","minecraft:dirt"]}
give @s netherite_axe{CanDestroy:["minecraft:pumpkin"]}

Solution 1:

The BE equivalents of these tags are minecraft:can_place_on and minecraft:can_destroy respectively. You can use these in the /give and /replaceitem commands using the final [components: json] argument. For example, the syntax of /give is:

give <player: target> <itemName: Item> [amount: int] [data: int] [components: json]

Note that unlike Java Edition, block names go inside an array named blocks that goes inside minecraft:can_place_on and minecraft:can_destroy. Like so:

give @s stone 1 0 {"minecraft:can_place_on":{"blocks":["grass","dirt"]}}
give @s netherite_axe 1 0 {"minecraft:can_destroy":{"blocks":["pumpkin"]}}

You can also combine both minecraft:can_place_on and minecraft:can_destroy:

give @s iron_block 1 0 {"minecraft:can_place_on":{"blocks":["iron_block"]},"minecraft:can_destroy":{"blocks":["grass","dirt"]}}

* The namespace value minecraft: is optional and can be omitted.

This syntax is called JavaScript Object Notation (JSON), which is a format similar to the NBT used in JE commands (technically SNBT). Objects are surrounded by braces ({ and }), have keys and values separated by colons (:), and have key-value pairs separated by commas (,). Keys and strings are surrounded by double quotes ("); arrays are surrounded by brackets ([ and ]) and contain items delimited by commas (,).
