## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Endpoint Security**: 80/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 69/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 913 tokens (~182/item across 5 items; 5 tools + 0 resources), over budget; trim descriptions and params.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 47/100
  - Stability observed for 14 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 5 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 6 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a current MCP spec version (2026-07-28).

### 2026-10-22 (score 73)

First indexed and scored.

## MCP tools (5)

### `check_post_quantum_tls` (~81 tokens)

Check post-quantum TLS

Does this public hostname negotiate hybrid post-quantum key exchange (X25519MLKEM768)? Returns TLS version, hybrid yes/no and a one-line verdict. Free. One TLS handshake per probe, no scanning.

Input parameters:

- `hostname` (string, required): Public DNS hostname, e.g. www.example.com. IP addresses and internal names are refused.

### `check_tls_certificate` (~68 tokens)

Check TLS certificate

Certificate issuer, expiry date, days left, and whether the chain verifies for the hostname from a strict client (catches missing intermediate certificates and name mismatches). Free.

Input parameters:

- `hostname` (string, required): Public DNS hostname, e.g. www.example.com. IP addresses and internal names are refused.

### `audit_wazuh_rules` (~223 tokens)

Audit Wazuh custom rules

Finds Wazuh custom rules that pass wazuh-analysisd -t but are dropped at load (load order across ruleset/rules and etc/rules, missing parents, duplicate or colliding ids). Input: list of {filename, xml}. Supported versions: 4.14.7, 4.14.9. Free: counts + 2 findings. Full report: pass api_key.

Input parameters:

- `api_key` (string): Optional key for the full report. Without it you get counts and 2 findings; the full report is also sold per call by x402 at POST https://atkvn.com/agent/v1/wazuh-audit.
- `files` (array, required): Custom rule files, each {"filename": "0094-local.xml", "xml": "<group>...</group>"}; filename exactly as in /var/ossec/etc/rules/, up to 20 files.
- `wazuh_version` (string): Wazuh manager version: 4.14.7 or 4.14.9.

### `test_wazuh_rule` (~243 tokens)

Test Wazuh rule on a real manager

Runs log lines through a real wazuh-manager 4.14.9 (fresh logtest session) with your custom rules and decoders: which decoder and rule matched, whether YOUR rule fired, and load warnings such as 7617/7619. Logtest engine: frequency/timeframe rules and some live-only behaviour are out of scope. Free: 1 log line with your files (3 with the stock ruleset only), summary. 10 lines with decoded fields and full alerts: POST https://atkvn.com/agent/v1/wazuh-testfire (x402, USD 0.10).

Input parameters:

- `decoders` (array): Optional custom decoder files, same shape as rules.
- `log_format` (string): Wazuh log_format, e.g. syslog or json.
- `logs` (array, required): Raw log lines exactly as the agent would forward them, one event per item.
- `rules` (array): Optional custom rule files: [{"filename": "0096-local.xml", "xml": "<group>...</group>"}]. Filename order matters: files load by name together with the stock ruleset.

### `check_php2shell` (~187 tokens)

Check PHP2Shell (CVE-2026-109618/109619)

Is this PHP install exposed to PHP2Shell, the two critical unauthenticated RCE flaws patched on 21 Oct 2026 (CVE-2026-109618, CVE-2026-109619)? Paste local evidence collected on the server: `php -v`, `php -i` or `php-fpm -i`, `cat /etc/os-release`, `dpkg -l 'php*'` or `rpm -qa 'php*'`. Returns patched / vulnerable / check_vendor_backport, the exact changelog command that decides distribution builds, upgrade commands, config mitigations until patched, and a tested Wazuh rule pack for crash and OOM signals. Free. Nothing is fetched from your servers.

Input parameters:

- `evidence` (string, required): Raw output of the commands above, pasted as one text block (up to 20 KB).
