// key findings
✅
No credential exfiltration, no sensitive file access, no obfuscation
Static analysis found nothing flowing your secrets to unexpected places.
🔐
You'll be asked for 1 credential: MSSQL_PASSWORD
These are read from process.env at runtime. Make sure you trust where they’ll be sent.
// 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.
configMSSQL_CLIENTClient key under clients (e.g. database name QASandbox8)
configMSSQL_CONFIG_PATHPath to the JSON file (default connections.json, resolved from current working directory)
configMSSQL_DATABASEDatabase name (default master)
configMSSQL_ENCRYPTtrue or false (default false)
configMSSQL_ENVIRONMENTEnvironment key (e.g. staging, prod)
🔐 secretMSSQL_PASSWORDLogin password (omit for Windows Integrated)
configMSSQL_PORTMCP server for Microsoft SQL Server with explicit port support. Works from Claude Code, Cursor, and CLI; default port is 9123 (override with ).
configMSSQL_SERVERServer host (e.g. 192.168.100.65)
configMSSQL_TRUST_CERTSet to true for self-signed / dev (or use MSSQL_TRUST_SERVER_CERTIFICATE)
configMSSQL_TRUST_SERVER_CERTIFICATESet to true for self-signed / dev (or use MSSQL_TRUST_SERVER_CERTIFICATE)
configMSSQL_USERLogin user (omit for Windows Integrated)

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

3/3 tools missing one or more hints — query (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_tables (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); describe_table (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint). 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.

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