genMC knowledge base

A Minecraft studio in the browser that you and your AI agent use together: skins, builds and more, live in one tab.

Make your first skin and your first build, connect an agent and take the result into Minecraft – in ten minutes.

The header, document row, agent column, dock and timeline that the studios share, plus settings, language and dark mode.

Classic and Slim models, the base and outer layer, 3D, 2D and split view, body parts and saved skins.

Pencil, eraser, face fill, colors and presets, and how to mark areas for your agent.

Let your agent restyle a skin (Simple, Balanced, Graphic, Strong shading) or prepare several options to choose from.

Import a PNG or a player's skin, export the Minecraft PNG, render images, and what the invisible marker in exports is.

Undo and redo, play back a skin's history, compare versions, revert a single change and save named checkpoints.

Projects, the growing plot, the full Java block library, textures and how you and your agent share the work.

Look around, fly through your build, use the view cube and cut it open with the slicer.

Brush, Surface and Smart marking, adding and removing marks, and how marks travel with your requests.

Browse, hide and isolate the parts of a build, get a bill of materials with stacks and shulker boxes, and estimate the survival effort.

Walk through your build like in Minecraft, play the agent's room tour and render it as an MP4 video.

Redstone just works in the 3D view – click a lever or button and lamps light, pistons push and doors open, like in Minecraft Java, in real game ticks.

Look at earlier versions and replay how a build grew without disturbing your agent; restore, undo and redo when you mean it.

Download a build as JSON, .schem for WorldEdit, .mcfunction for datapacks, PNG or tour video – and bring JSON back in.

What an agent can do in genMC, the two ways it connects (site tools and the MCP relay), and the safeguards that keep you in control.

Pair Claude, ChatGPT, Claude Code, Codex or another MCP client with your studio tab using a short code – step by step, with troubleshooting.

Send requests with marks and photos, follow the agent's progress, read the statuses and end a session with Finish.

The rules and the working loop for AI agents in genMC – revisions, requests, previews, named parts, renders and Finish.

Every tool a connected agent can call, generated from the running studio code.

Why an account is optional, how to sign in with an e-mail code or Google, and what happens to your work when you sign in or out.

Publish skins and builds to the public gallery, remix other people's work, report problems, and share a build privately with a secret link.

Where your work is saved, what stays private, what the developer can see, and how saving conflicts are handled.

Every keyboard shortcut of the skin studio, the build studio, flight, walk mode, the agent input and this knowledge base.

All sizes, counts and rate limits in one place – skins, builds, history, requests, agents, publishing and accounts.

Solutions for the most common problems – agent connection, queued requests, saving conflicts, lost work, exports and performance – and how to send feedback.

Short definitions of the terms used in genMC and in this knowledge base.
