Click "Multiplayer" then "Add Server" . You need the proxy address. For example: ws://eaglercraft.example.com:8080 (Note: Eaglercraft uses WebSocket ws:// not TCP mc://).
To understand Eaglercraft 2b2t, one must first understand the tool. Eaglercraft was a reverse-engineered port of Minecraft 1.5.2 (and later 1.8.8) that ran entirely within a web browser using HTML5 and WebGL.
Originally developed by a creator named lax1dude, Eaglercraft allowed users to play Minecraft on nearly any device—Chromebooks, school computers, and low-end laptops—without downloading the game or owning a Microsoft/Mojang account. It was "cracked" Minecraft for the browser age.
While Eaglercraft supported single-player and custom servers, the ultimate draw for many players was connecting to the "Motherland": 2b2t.
While the concept is exciting, there are real dangers:
Without aim-assist, killaura, or even reliable hit registration, you are free loot. Players using full Java clients will kill you before your browser registers the attack.
Short answer: Yes, but with significant caveats.
The vanilla 2b2t server does not support Eaglercraft directly. To play, you need a third-party proxy that sits between your browser and 2b2t. Here is the technical flow:
Your Browser (Eaglercraft) —[WebSocket]—> Public Proxy Server —[TCP/Minecraft]—> 2b2t.org
Several community members have set up public proxies specifically labeled "Eaglercraft 2b2t." These proxies log into 2b2t using a bot account and then stream your input to the server.

Verdict: Eaglercraft 2b2t is viable for tourism—exploring spawn, seeing the ruins, chatting—but not for serious anarchy PvP or large-scale building projects.
