Security intelligence via x402 on Base. CVE lookup, IP reputation, secret scanning.The vendor's description, from its MCP Registry listing.
- Warning: 3 of 3 tools do not say whether they can change things.
Nothing failed, but there is something to know or fix. Public audit: we connect as an AI client would, list the tools and check what they say. We do not run them. How we audit

What we checked
Security
Passed: Connections are encrypted (HTTPS).
Passed: No hidden instructions found in tool text.
Safety labels
Warning: 3 of 3 tools do not say whether they can change things.
MCP lets a server label each tool as read-only or destructive, so clients can ask the user before risky calls. Unlabelled tools are treated as able to change things.

- reputation_check
- secret_scan
