Browse the guides below or reach us directly at support@sequel.sh. We typically respond within one business day.

Getting started

Sign in at sequel.sh and go to Data Sources in the left sidebar.
Click New Connection and choose your data source (PostgreSQL, MySQL, ClickHouse, Google Analytics, and more).
Follow the connection steps — either paste a connection string or authenticate via Google OAuth.
Once connected, add Sequel as an MCP server in your AI tool of choice (Claude Code, Claude Desktop, ChatGPT, Cursor, and others).
Start asking questions about your data directly in your AI client.

How do I get my API key? Go to Settings → API Keys and click New Key.
How do I add Sequel to Claude Code? Run: claude mcp add sequel --transport http https://api.sequel.sh/mcp --header "Authorization: Bearer sql_your_api_key"
How do I add Sequel to Claude Desktop? Edit your claude_desktop_config.json and add Sequel under mcpServers with your API key.
How do I add Sequel to ChatGPT? Enable Developer Mode in Settings → Apps → Advanced Settings, then create a new app with the MCP Server URL https://api.sequel.sh/mcp and OAuth as the authentication method.
Can I connect multiple databases? Yes. Add as many data sources as you need from the Data Sources page.
Is my data stored by Sequel? No. Query results are returned to your AI client and not persisted on Sequel's servers.

Connection failing: Check that your connection string is correct and that your database accepts inbound connections from external IPs. For cloud databases, you may need to whitelist Sequel's servers.
MCP server not showing up: Restart your AI client after adding the MCP config. Most clients only load MCP servers at startup.
OAuth not working: Make sure you're signing in with the Google account that has access to the property you're trying to connect.
API key rejected: Check that you copied the full key including the sql_ prefix and that it hasn't been revoked. You can create a new key in Settings → API Keys.
No data returned: Confirm the data source connection is active in Sequel and that your AI client has the Sequel MCP tools loaded.

Send us the details of what you're running into and we'll get back to you.
