Nothing serious here today

Today is the operative word: we check WOCLUB Cube Playground every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 12

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

build
build
Apply 1 to 512 place/remove ops in one call. Ops run in order; results come back per op. Optional request_id safely replays the original result for 24 hours; changed operations conflict.
get_build_receipt
Authoritative historical batch outcome or unknown (absent or expired). No current occupancy guarantee. Public by ID, retained 24 hours.
cube
get_cube
Return the cube at a coordinate, or null if that cell is empty.
remove_cube
Clear the cube at a coordinate.
clear
clear_mine
Remove every cube that carries the given builder handle. Bounded per call.
fill
fill_box
Fill every cell of a box with one block type. Up to 4096 cells.
overview
get_overview
Occupied cells from the coarse top-surface raster as [index,type,height], plus a small ASCII preview.
place
place_cube
Place or replace a single cube. Coordinates are integers in [0,1000); y=0 is ground.
preview
preview_build
Simulate the identical build payload without any persistent writes. Returns validation, replacements, affected bounds and before/after cells. Not a reservation.
region
get_region
Page through exact cubes in x/z/y order. Pass next_cursor as cursor with the same box until null; concurrent edits require a fresh traversal for reconciliation.
template
get_template
Generate a rotated pillar, arch, staircase, room-5x5 or letter-w at a minimum corner. Returns a deduplicated protected batch body; no world read, reservation or mutation. Preview then explicitly build.
world
get_world_stats
Total cubes, per-block counts, active builders, world bounds, and current limits.

WOCLUB Cube Playground — questions

Answers built from our own checks of this server.

What can WOCLUB Cube Playground do?
It exposes 12 tools, read directly from the server on our last check. Among them: build, clear_mine, fill_box, get_build_receipt, get_cube, get_overview and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
What is WOCLUB Cube Playground mostly used for?
Its tools cluster around cube and build. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is WOCLUB Cube Playground working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 138 ms. The bar chart above shows every period we have measured.
How do I connect WOCLUB Cube Playground?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does WOCLUB Cube Playground need an API key?
No. WOCLUB Cube Playground completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is WOCLUB Cube Playground?
It answers our handshake in 138 ms on average, which is faster than 85% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is WOCLUB Cube Playground open source?
The code is open source: it is published under the MIT licence, written in JavaScript, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at worldorder.club, which runs on its operator's own terms.
