1 flow detected: RESEND_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🔐
You'll be asked for 14 credentials: GH_MCP_TOKEN, MCP_BEARER_TOKEN, RESEND_API_KEY, SUPABASE_SERVICE_KEY, LEMONSQUEEZY_WEBHOOK_SECRET, LEMONSQUEEZY_API_KEY, SUPABASE_WEBHOOK_SECRET, RESEND_WEBHOOK_SECRET, ANTHROPIC_API_KEY, GEMINI_API_KEY, COMPOSIO_API_KEY, OPENAI_API_KEY, SUPABASE_JWT_SECRET, SUPABASE_ANON_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// 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.

// 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 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
