⚠️

Tests do not pass

Either the test suite is broken or the code regressed. Either way the published behaviour can’t be verified by the publisher’s own tests.

✅

103 tools verified — handlers match their declared behaviour

103 read-only tools verified — handlers contain no write/delete/exec

✅

No credential exfiltration, no sensitive file access, no obfuscation

✅

Open source with a license and README

Anyone can audit the code, the license is declared, and the publisher documents what it does.
