Secret credentials may flow to a network call

2 flows detected: GOOGLE_API_KEY. We can’t prove the destination matches the brand the credential belongs to.

⚠️

Tool descriptions don’t match what handlers do

3 tools describe read intent but their handlers mutate — search_knowledge (line 80: supabase.from("mcp_usage_logs").insert({); get_entry (line 80: supabase.from("mcp_usage_logs").insert({); search_by_tag (line 80: supabase.from("mcp_usage_logs").insert({)

🔐

You'll be asked for 3 credentials: GOOGLE_API_KEY, NEXT_PUBLIC_SUPABASE_ANON_KEY, SUPABASE_SERVICE_ROLE_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

// required environment variables
