// key findings
🚨
Known vulnerabilities in dependencies: 1 critical
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 3 credentials: MCP_AUTH_TOKEN, VONAGE_API_SIGNATURE_SECRET, VONAGE_WEBHOOK_SECRET
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// known CVEs in dependencies1 critical

Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configALLOWED_COUNTRY_CODES送信・架電を許可する国番号（カンマ区切り、+ の有無は問わない）。海外宛を使う場合は明示的に追加する。 を指定すると制限を外す（非推奨）。実在しない国番号を書くと起動エラーになる。
configALLOWED_NUMBERSClaude Desktop は 2026-08-24 に v1.34493 で確認しました。 MCPB のインストール、capability トグル、 によるブロック、SMS の実配信と音声通話の実発信、通話ステータスの取得、実行前の承認プロンプトまで動作しています。
configBIND_HOST
configLOG_FILE
🔐 secretMCP_AUTH_TOKEN$(openssl rand -hex 32)
configVOICE_INBOUND_MESSAGE音声の着信時に読み上げる文面。このサーバーは着信を処理しないため、既定では「お受けしておりません」という案内を読み上げて切る。1000文字以内（発信の読み上げと同じ上限）。着信は誰でも掛けられるため、長い案内文はそのまま通話時間と音声合成の課金になる。超過すると起動時にエラーで止まる。
🔐 secretVONAGE_API_SIGNATURE_SECRETStatus Webhook の署名検証に使う Vonage の Signature Secret。推奨。Vonage Dashboard の Settings → API settings で取得できる。
configVONAGE_APPLICATION_IDVonage Application ID
configVONAGE_PRIVATE_KEY_PATH秘密鍵ファイルのパス（例: /Users/your-name/vonage/private.key）
configVONAGE_VOICE_FROM音声通話用の電話番号（E.164形式、例: 81345438093）
🔐 secretVONAGE_WEBHOOK_SECRET署名検証が使えない環境向けの代替。設定すると x-webhook-secret ヘッダーの一致を要求する。VONAGE_API_SIGNATURE_SECRET が設定されている場合は使われない。Vonage は任意ヘッダーを送れないため、Vonage から直接呼ばれる Webhook には使えない（手前のゲートウェイがヘッダーを付与する構成でのみ有効）。
// quality suggestions

All four hints declared on every tool

2/4 tools missing one or more hints — get_call_status (missing: destructiveHint, idempotentHint); get_sms_status (missing: destructiveHint, idempotentHint). OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Secrets not logged

1 secret value sent to error

Redact or omit secret values from log output.

Dev dependencies

1 critical/high in dev-only deps (does not ship to users)

Upgrade dev dependencies when convenient.

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 3 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
