## Install

**Verdict: review** — Installable, but 2 things to check first: The last scan is 114 days old — the evidence behind this verdict is dated.
**Cautions** (coverage gaps and advisories — never blocking)
- The last scan is 114 days old — the evidence behind this verdict is dated.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mcp-comfy-ui-builder\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"mcp-comfy-ui-builder\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Extensive to critical — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: deletes data; runs on your machine.
- Floor 42, ceiling 66 (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.
