Limited view. Automated analysis covers part of this stack. Findings reflect what we verified. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

Limited view: static analysis for Python is partially covered.

// key findings
✅
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.
configDSO2D15_VISA_BACKENDmacOS: install includes pyusb so pyvisa-py can enumerate USB-TMC. If discovery still fails, try [NI-VISA](https://www.ni.com/en/support/downloads/drivers/download.ni-visa.html) and =@ni.
configDSO2D15_VISA_QUERYPattern for auto-pick when DSO2D15_VISA is unset. Default: USB0::1183::20574:? (Hantek DSO2000 IDs used by common tooling)
configDSO2D15_VISAFull VISA resource string, e.g. USB0::0x049F::0x505E::...::INSTR (use dso2d15_list_visa_resources to discover)
configDSO2D15_TIMEOUT_MSVISA read timeout in ms (default 120000; large captures can be slow)
configDSO2D15_SNAPSHOT_DIRDirectory for BMP/SVG files from dso2d15_measure_snapshot (default: system temp)
// quality suggestions

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

9/9 tools missing one or more hints — dso2d15_list_visa_resources (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); dso2d15_list_hantek_candidates (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); dso2d15_identify (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +6 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

8/9 tool handlers declare input schemas (89%)

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

Tests exist

No test files found

// 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 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
