// key findings
🚨
Secret credentials may flow to a network call
1 flow detected: OPENAI_API_KEY. We can’t prove the destination matches the brand the credential belongs to.
🚨
Known vulnerabilities in dependencies: 1 critical, 3 high
Affects packages this MCP installs at runtime. Upgrade or remove the affected dependency.
⚠️
Tests do not pass
Either the test suite is broken or the code regressed. Either way the published behaviour can’t be verified by the publisher’s own tests.
🔐
You'll be asked for 2 credentials: ANTHROPIC_API_KEY, OPENAI_API_KEY
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
