cloud-sql-mssql

cloud-sql-mssql is an MCP server for Claude Code from gemini-cli-extensions/cloud-sql-sqlserver. Its token cost is not measured, scanned A, original, Apache-2.0.

A local command-line server that connects tools to a Microsoft SQL Server database hosted through Google Cloud SQL.

In plain words
What is it for?
Use it when access is needed to a Cloud SQL for Microsoft SQL Server project, region, instance, database, and credentials.
Why use it?
It provides a configured connection path so an agent can work with that database without manually assembling the server command and connection settings.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo
git clone --depth 1 https://github.com/gemini-cli-extensions/cloud-sql-sqlserver

Made for: Claude Code.

Security

Grade A, and why

cloud-sql-mssql scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
