EVM token contract safety check: honeypot detection, mint/blacklist/pausable/self-destruct capability, ownership renouncement, transfer tax, and a real token-impersonation check (does the symbol claim to be USDC/WETH/DAI/cbBTC at the wrong address — the token equivalent of npm typosquatting).

PreFlight Checker · MCP Audit

x402-api-catalog.onrender.com

MCP server safety audit: completes a real initialize+tools/list handshake, then statically scans every tool's name/description/schema for hidden unicode (tool-poisoning), prompt-injection-style phrasing, and tools that quietly combine multiple high-privilege capabilities (network+filesystem+exec+credential access). If a GitHub repo is supplied, folds in a real software-supply-chain signal too.
