**Verdict: install** — No blocking findings and no open coverage gaps — safe to install as configured.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"server\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"@mastyf_ai/server\"\n      ]\n    }\n  }\n}"
```

## Blast radius

Contained to critical — no readable artifact — tool surface unknown. Known so far: runs on your machine; 60 transitive dependencies.
- Floor 10, ceiling 78 (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.
