## Trust

60/100 (B), scored on the content rubric
- Publisher verified: no
- Install scripts: nothing suspicious found
- Prompt-injection scan: clean
- Obfuscation scan: clean
- Evidence age: 33 days

## Security scan

- **Status:** clean
- **Scanned:** 2026-09-02T05:05:47.913Z
- **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.

## Tools

3 declared. Observed from a live `tools/list` probe.
- `kavra_siegel_stamp_hash` — Erzeugt einen qualifizierten eIDAS-Zeitstempel für einen SHA-256-Hash. RFC 3161 via SIGNIUS/IDnow Trust Services AB (EU Trusted List).
- `kavra_siegel_stamp_content` — Erzeugt einen qualifizierten eIDAS-Zeitstempel für base64-encodierten Inhalt (max 1 MB). Hash wird serverseitig berechnet. RFC 3161 via SIGNIUS/IDnow.
- `kavra_siegel_verify_token` — Verifiziert einen Stempel-Token anhand seiner UUID.

## 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    \"kavra-siegel\": {\n      \"type\": \"http\",\n      \"url\": \"https://siegel.kavra.cloud/mcp\"\n    }\n  }\n}"
```

## 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.
