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.
