// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: REPLICATE_API_TOKEN. We can’t prove the destination matches the brand the credential belongs to.
⚠️
Tool descriptions don’t match what handlers do
1 tool describes read intent but its handler mutates — build_rom (line 105: fs.mkdir(ctx.config.romOutputDir, { recursive: true }))
🚨
Known vulnerabilities in dependencies: 1 critical, 2 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
🔐
You'll be asked for 5 credentials: FAL_KEY, GEMINI_API_KEY, GOOGLE_API_KEY, OPENAI_API_KEY, REPLICATE_API_TOKEN
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
