Connect PostgreSQL to Claude
Query your PostgreSQL data directly from Claude using Sequel’s MCP server. Ask questions in plain English — no SQL, no dashboards, no context switching.
How it works
Three steps to get started
Connect PostgreSQL to Sequel
In your Sequel dashboard, go to Connections and add PostgreSQL. Sequel handles authentication and schema discovery automatically.
Add the MCP config
Copy the Sequel MCP configuration into Claude's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask Claude about your data
Restart Claude and start asking questions. "How many rows are in each table?" — and get a real answer backed by live PostgreSQL data.
Configuration
Add Sequel to Claude
Place this in ~/Library/Application Support/Claude/claude_desktop_config.json and replace sql_your_api_key with a key from Settings → API Keys.

Questions you can ask Claude
Frequently asked questions
How do I connect PostgreSQL to Claude?
You need two things: (1) connect PostgreSQL to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Claude using the setup shown above. Once both are done, Claude can query your PostgreSQL data directly.
What PostgreSQL data can Claude access?
Claude can access any data available through your PostgreSQL connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.
Is my PostgreSQL data sent to Claude's servers?
Query results are returned to Claude as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.
Do I need a Sequel account?
Yes. You need a Sequel account to connect PostgreSQL and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to PostgreSQL and generate an API key from Settings → API Keys.
Can I connect multiple PostgreSQL accounts?
Yes. Sequel supports multiple connections of the same type. If you have multiple PostgreSQL accounts or properties, add each as a separate connection in Sequel. Claude will be able to query all of them.
