Common questions
Claude and SQL Server FAQ
Can Claude connect to SQL Server?
Yes. The connector can work with Microsoft SQL Server when you provide a reachable server, a supported authentication method and permission to the data you want Claude to use.
Is the Claude database connector free?
The BlazeSQL connector is free to add from Claude’s directory. Your Claude workspace or the service you choose to use outside the connector may have its own plan limits.
Do I need Claude administrator access?
Not on every account. If your Claude Team or Enterprise workspace restricts connectors, a workspace Owner may need to enable it. You can use BlazeSQL directly while waiting.
Can I complete the setup on a phone?
You can open and save the guide on mobile, but database credentials and network access are usually easier to manage from a computer.
