MCP servers that fail: no install/post-install scripts
371 of the 8,573 Model Context Protocol servers where this control could be evaluated fail it — that is 4% of the evaluated corpus on the Canopii Trust Index.

Why this matters
install hooks run arbitrary code on every consumer at install time.
How to pass it
Remove preinstall/install/postinstall scripts, or document and minimize them.
Control id supply.no_install_scripts — a guard control, so a confirmed failure caps the server's score at the medium ceiling no matter what else passes.
