// key findings
⚠️
Tool descriptions don’t match what handlers do
1 tool describes read intent but its handler mutates — cadsmith_assembly (line 171: part_json_path.write_text()
✅
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.

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

18/18 tools missing one or more hints — gui_server (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); rocketsmith_setup (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); cadsmith_assembly (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +15 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.

Descriptions match behaviour

1 tool describes read intent but its handler mutates — cadsmith_assembly (line 171: part_json_path.write_text()

Rename the tool, rewrite the description, or move the side-effect into a separate clearly-named tool.

Tool handlers catch errors

15/17 tool handlers wrap calls in try/catch (88%)

Wrap each tool handler body in try/catch and return a structured error response.

Tool test coverage

Only 0/18 tools referenced in tests (0%)

Write tests that reference each tool by name so every tool has at least one test.

Tool description accuracy

cadsmith_assembly: description implies read-only but handler writes/deletes/executes

Update tool descriptions to accurately reflect all capabilities — especially write, delete, or execute operations.

// 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 6 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
