## Security scan

**Assessment scope:** Hosted endpoint only: Forge can assess who publishes it and whether it answers, not the code behind it. No CVE, dependency or source analysis applies, so nothing here is a clean bill for that code.
- **Status:** probed (endpoint answered; no code examined)
- **Scanned:** 2026-08-17T13:26:43.245Z
- **Version scanned:** live
- **CVEs:** no coverage — this entry has no package coordinates to query OSV against, so "no known CVEs" is NOT asserted for it.

## Install

**Verdict: review** — Installable, but 3 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.
- Hosted endpoint only: Forge can assess who publishes it and whether it answers, not the code behind it. No CVE, dependency or source analysis applies, so nothing here is a clean bill for that code.
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"mailbox\": {\n      \"type\": \"http\",\n      \"url\": \"https://mailbox.bot/api/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: mutates data; runs on someone else's infrastructure.
- Floor 26, ceiling 50 (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.
