Show HN: I made Claude play Minecraft using Agent SDK

https://github.com/haksndot/haksnbot-agent
4•haksndot•2h ago
This weekend I built a Minecraft bot for a server I play on. It uses the Agent SDK for the main loop and a bunch of custom MCP tools.

Some highlights:

* The bot is an active participant in the in-game chat, enabling all players to interact with it.

* Tools for interacting with containers, crafting, trading with villagers and various other things.

* Memory system which the agent uses to keep track of in-game events, interactions with players etc.

* Screenshot tool which lets Claude use its vision modality to look around (not very useful, but fun).

* Tooling for interacting with plugins GriefPrevention and QuickShop, so the bot can manage land claims and shops.

* Tools for doing server administration, running server commands etc. This is a separate, optional tool set, in a separate repo.

As of this writing, there are 69 tools. We keep adding more on the fly as we come up with new ideas in the player community. About two thirds of the tools are wrappers around Mineflayer.

100% vibe coded. Not a single line of code written or even read by a human.

MIT License. If you try this thing out, I would love to hear about it!
