// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
// 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.
configOPEN_PATH/usr/bin/open Path to macOS open
configPARALLELS_APP_NAMEParallels Desktop App name for open -a
configPARALLELS_AUTO_OPEN_ON_VM_STARTtrue Set false to disable auto-open on start/resume/restart
configPARALLELS_INIT_WAIT_MS3000 Milliseconds to wait after opening Parallels
configPARALLELS_OPEN_IN_BACKGROUNDfalse Set true to use open -g for auto-open (no focus steal)

Tool annotations

No tools have read-only/destructive annotations

Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.

All four hints declared on every tool

11/11 tools missing one or more hints — open_parallels_desktop (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_vms (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_running_vms (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +8 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

Tool inputs are validated

Only 3/11 tool handlers declare input schemas (27%)

Declare an inputSchema with zod/joi/yup on every tool definition.

License file

No license file

Add a LICENSE file (MIT, Apache-2.0, etc.).

Tests exist

No test files found

Add tests that exercise each declared tool.

// 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.
// improvement guidance — verified publishers only
We have 5 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
