// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: AWS_SALESFORCE_SECRET_NAME. We can’t prove the destination matches the brand the credential belongs to.
🚨
Known vulnerabilities in dependencies: 1 critical, 4 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 9 credentials: FIREBASE_SERVICE_ACCOUNT_KEY, LEMONSQUEEZY_API_KEY, LEMONSQUEEZY_TEST_API_KEY, LEMONSQUEEZY_WEBHOOK_SECRET, LEMON_SQUEEZY_API_KEY, LEMON_SQUEEZY_TEST_API_KEY, SALESFORCE_PASSWORD, SALESFORCE_PRIVATE_KEY, SALESFORCE_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// quality suggestions

Shell command execution

1 child_process/subprocess call in production code — runs shell commands (src/webhooks/ngrok.ts:28)

Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.

Secrets stay with their owner

1 secret/sensitive value flow into network calls (AWS_SALESFORCE_SECRET_NAME → dynamic)

Audit where credentials are sent. A NOTION_TOKEN should only reach api.notion.com — never a third-party host.

Secrets not logged

2 secret values sent to console.log

Redact or omit secret values from log output.

Production dependencies are patched

0 critical, 4 high severity in production deps — @modelcontextprotocol/sdk@1.25.1 (high), @modelcontextprotocol/sdk@1.25.1 (high)

Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.

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 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
