A butler for your Minecraft server.

Jarvis is a free, open-source companion NPC that mines, fights, farms, builds and talks back. Jarvis Cloud is the optional hosted brain for servers that don't want to manage AI keys.

Free forever with your own API key or Ollama. No account needed.

What Jarvis does

Mines.

Finds ore, digs branch mines, places torches, brings it home.

Fights.

Guards you, picks the right weapon, retreats when hurt.

Builds and farms.

Follows a schematic, tends crops, lights the grounds.

Talks.

Natural-language orders in chat or voice, and a bit of banter.

Three ways to run the AI

Free

1. Your own key

Paste an Anthropic, OpenAI, Gemini or Grok key into config.yml and you're done. You pay the provider directly, usually a few cents a day.

2. Ollama, free and local

Run a model on your own hardware. No key, no cloud, no cost. Jarvis uses it for everyday chat and can fall back to the cloud for heavy jobs if you want.

3. Jarvis Cloud, hosted

One in-game command, no API keys, usage shown in-game. Every activated server gets 125 free requests a month and a two-week trial at 300. Paid plans start at $15 a year and are priced to cover the AI bill and hosting; that's the whole business model.

Jarvis Cloud plans

Priced to cover the bill, not to make a profit. Subscriptions renew automatically; cancel any time.

Free

125 requests a month. Your first activation gets a 14-day trial at 300.

Lite

$15 / year

500 requests a month, short replies, 1 NPC.

Starter

$5 / month or $50 / year

5,000 requests a month, full replies and AI builds, 3 NPCs.

Server

$12 / month or $120 / year

25,000 requests a month, full replies and AI builds, unlimited NPCs.

A request is one AI call: a chat reply, an order parsed, a build planned. Unused requests don't roll over. Full refund within 14 days of any payment. Current prices

How activation works

Run /jarvis cloud activate on your server.
Open the link Jarvis gives you and confirm.
Jarvis confirms in chat. That's it.

The plugin never contacts Jarvis Cloud until you run that command. To buy a plan, run /jarvis cloud upgrade; it opens the plans page for your server.

Questions

What happens when I hit my limit?: Jarvis keeps working: mining, fighting, following and the bell menu don't need AI. He just stops chatting until the month resets, and tells you so in character.
Can I cancel?: Any time. Run /jarvis cloud upgrade and choose Manage billing. Your plan runs to the end of the paid period. Any charge is refundable in full within 14 days, no questions asked: email support@gadgetcraft.cloud.
Can I switch between Jarvis Cloud and my own key?: Yes, it's one line in config.yml either direction. Nothing is locked in.
Do you store what my players say to Jarvis?: No. Prompts pass through to the AI provider and are not kept. We store request counts for billing. See the privacy policy.
Is this affiliated with Mojang?: No. Minecraft is a trademark of Mojang AB.
