How MarketNow scored this

Sentinel Index Heuristics — a security-first estimate from public signals:

Typosquat distance against the 150 most-installed MCP packages
Injection markers scanned in the package description

Heuristic, not a guarantee. For verified agent credentials and revocation, see the MarketNow Trust API.
