## Install

**Verdict: do-not-install** — Do not install: 3 injection-shaped patterns found in this entry's own text — it may try to steer the model that loads it.
**Blocking**
- 3 injection-shaped patterns found in this entry's own text — it may try to steer the model that loads it. — tool:my_collection: Exfiltration-shaped instruction · tool:search_my_collection: Exfiltration-shaped instruction · tool:what_can_i_build: Exfiltration-shaped instruction
**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.
**Client configuration withheld.** Client configs are withheld because this entry has a blocking finding. Show the warnings below to the person installing it.
If they have seen the findings and still want to proceed, request the plan again with acknowledge_warnings=true.

## Blast radius

Contained to moderate — no credential declaration found, from the publisher, the upstream registry, or the README. Known so far: runs on someone else's infrastructure; read-only tool surface.
- Floor 9, ceiling 27 (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.
