B Why this grade 100 − 15.4 = 85/100

Every server starts at 100. These are the exact deductions the deterministic engine applied — each one reproducible, none of it an opinion or an LLM's guess:

Findings 1

high Package runs install-time scripts (preinstall)MTC-SUP-010

"@postman/postman-mcp-server" executes preinstall script(s) at install time. The large majority of malicious packages abuse install hooks to run code before you ever import them.

Fix: Review the scripts; install with --ignore-scripts where possible and vet what they do.

Show this server's live Trust Score in your README, docs or website. The badge is served straight from the registry and updates automatically after every rescan — no API key needed. It links back to this page, so anyone who sees the grade can also read the findings behind it instead of taking a number on faith.
