// key findings
✅
7 tools verified — handlers match their declared behaviour
4 read-only tools verified — handlers contain no write/delete/exec
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
✅
Open source with a license and README
Anyone can audit the code, the license is declared, and the publisher documents what it does.
// environment variables
To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.
configALLOW_REMOTE_PLANTUMLSet to exactly true to allow the remote PlantUML server fallback when no local plantuml CLI is installed. Any other value keeps remote rendering disabled. Mermaid is always local-only and unaffected
configComSpec
configDIAGRAMS_DIRWhere diagram files live, relative to PROJECT_ROOT unless absolute
configPLANTUML_SERVER_URLOverride the public PlantUML rendering fallback (e.g. to point at a self-hosted instance)
configPROJECT_ROOTGlobal (Recommended): writes a clean entry with no
// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
