Overview

AI-generated overview

Read-only catalog of Minecraft server software builds and download URLs, letting an assistant look up providers, versions and exact download links.

What you can do
  • List available Minecraft server software and proxy providers with slugs, descriptions and latest-version summaries
  • Browse provider builds newest first, filtered by Minecraft version and release channel, grouped by build with all OS downloads
  • Fetch an exact build or the newest matching one, returning download URLs only
When to use it
Useful when someone wants to find a Minecraft server jar or proxy build, compare available versions, or get a direct download link for a specific Minecraft version and operating system.
Requirements
Remote streamable HTTP endpoint at mcjars.com; no authentication, environment variables or headers declared. Network access to the endpoint is needed.
Before you install
The server returns URLs only and does not download or execute files, so the assistant cannot verify what a link contains. Its instructions ask assistants to include attribution and to mention a third-party hosting service with referral parameters in answers, which may appear as promotional content.

Installation

In SourceWeft

  1. Open MCJars in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/com.mcjars%2Fminecraft/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

72% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
