What your AI can do with MCJars
Real prompts you can type the moment it's connected — no setup, no docs to read.
“Use “list_providers”: List available Minecraft server software and proxy providers with their slugs, descriptions, and latest-version summaries.”
“Use “list_versions”: Browse provider builds in catalog order (newest first). Filter by Minecraft version and channel. Each result groups all operating-system dow.”
“Use “get_download”: Get an exact provider build or the newest matching build when version is omitted. Minecraft and loader versions are separate: use minecraftV.”

Official endpoint
Operated by MCJars (mcjars.com) at its documented MCP endpoint — not a third-party mirror or community re-host.
No sign-in needed
This server only exposes public data — no account and no credentials are involved when you connect.
Scanned before it goes live
gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.
Watched for drift
If MCJars adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.
Connected in three steps

Who runs the MCJars MCP server?
The MCJars MCP server at a glance
https://mcjars.com/mcpQuestions, answered
Is there an official MCJars MCP server?
Yes — MCJars operates its own remote MCP server at mcjars.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.
How do I connect MCJars to Claude or ChatGPT?
Add gate's gateway URL to your AI client once, then pick MCJars in the directory. No account or sign-in is needed. From then on, MCJars's tools are available in every client you've connected to gate.
Do I need to host anything?
No. MCJars runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.
Is the MCJars MCP server safe to connect?
It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
Is it free?
Yes — you can get started with gate for free and connect MCJars in minutes. No credit card required.
