Three steps
Connect Claude to PostgreSQL

Open the BlazeSQL connector on Claude
The button above takes you directly to the BlazeSQL listing on claude.ai, so you do not need to search the directory.
-
02
Add or enable the connector
Follow Claude’s prompt to add the connector. On a Team or Enterprise workspace, an Owner may need to enable it first.
-
03
Connect PostgreSQL
Choose PostgreSQL, enter the approved connection details and select the data Claude should be able to use.
Before you start
What you need for PostgreSQL
- PostgreSQL hostname and database name
- Port (commonly 5432)

Use BlazeSQL directly instead

Common questions
Claude and PostgreSQL FAQ
Can Claude connect to PostgreSQL?
Yes. You can connect Claude to PostgreSQL by providing the server, database, credentials and SSL settings required to reach your PostgreSQL instance.
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.
