// 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.
configAUDIT_LOG✗ false Set to true to write JSON audit events to stderr
configDATABASE_URLSConditional - Multiple PostgreSQL URLs as alias=url pairs or JSON
configDEFAULT_DATABASE✗ default Default alias used when tool input omits database
configMAX_ROWS✗ 500 Default maximum rows returned
configMAX_STATEMENTS✗ 10 Maximum semicolon-separated statements per multi-statement tool call
configSTATEMENT_TIMEOUT_MS"": "5000",
Deployment configuration, supplied by whoever hosts the server. Users are not asked for these.

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

14/14 tools missing one or more hints — db.databases (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); db.schema (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); db.query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +11 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

13/14 tool handlers declare input schemas (93%)

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

Tool handlers catch errors

13/14 tool handlers wrap calls in try/catch (93%)

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

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
