## Security scan

- **Status:** clean
- **Scanned:** 2026-09-08T18:36:36.426Z
- **Version scanned:** HEAD
- **CVEs:** no coverage — this entry has no package coordinates to query OSV against, so "no known CVEs" is NOT asserted for it.

## Tools

11 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `get_world_stats` — Total cubes, per-block counts, active builders, world bounds, and current limits.
- `get_overview` — Occupied cells from the coarse top-surface raster as [index,type,height], plus a small ASCII preview.
- `get_region` — List the exact cubes inside an axis-aligned box.
- `get_cube` — Return the cube at a coordinate, or null if that cell is empty.
- `place_cube` — Place or replace a single cube. Coordinates are integers in [0,1000); y=0 is ground.
- `remove_cube` — Clear the cube at a coordinate.
- `build`
- `preview_build` — Simulate the identical build payload without any persistent writes. Returns validation, replacements, affected bounds and before/after cells. Not a reservation.
- `fill_box`
- `clear_mine` — Remove every cube that carries the given builder handle. Bounded per call.
- `build_something` — Use the ready-made non-overwriting signal-spark build, choose your builder handle, then read it back.

## Install

**Verdict: review** — Installable, but 2 things to check first: No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
**Cautions** (coverage gaps and advisories — never blocking)
- No CVE coverage: this entry has no npm/PyPI coordinates to query OSV against, so "no known vulnerabilities" is not a claim that can be made about it.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"cube-playground\": {\n      \"type\": \"http\",\n      \"url\": \"https://worldorder.club/mcp\"\n    }\n  }\n}"
```

## Blast radius

Moderate to extensive — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: deletes data; runs on someone else's infrastructure.
- Floor 32, ceiling 56 (tier: unknown)
- `unknown` means the floor and ceiling land in different bands — not measured enough to name one. It does not mean low.
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
