BlazeSQL on Claude
BlazeSQL integrates directly with Claude, Anthropic's AI assistant. Once connected, you can query your databases using natural language — whether you're using claude.ai in the browser or the Claude Desktop app.
How It Works
BlazeSQL appears as a connector in Claude. When you ask a question about your data, Claude uses BlazeSQL to:
Translate your natural language question into SQL
Run the query securely against your connected database
Return the results directly in the conversation
BlazeSQL only reads your data — it never modifies or deletes anything. Your database credentials stay in your BlazeSQL account, and only metadata (table and column names) is used to generate queries.
Setting Up on Claude.ai
A Blaze Team Advanced subscription
A BlazeSQL account with at least one connected database
A Claude Pro or Team subscription (connectors require a paid plan)
Step 1: Find BlazeSQL in Claude's Connectors
Go to claude.ai and open a new conversation. Click the Connectors or Integrations menu and search for BlazeSQL.
Step 2: Sign In and Select Your Database
Claude will open a BlazeSQL login window. Sign in with your BlazeSQL credentials — the same account you use at app.blazesql.com. Then choose which database you want to query.
Step 3: Query Your Data
You're all set. Ask Claude anything about your data:
"What were our top-selling products last month?"
"Show me the monthly recurring revenue trend"
"Which support tickets are still unresolved from last week?"
Setting Up on Claude Desktop
Step 1: Open MCP Settings
In Claude Desktop, go to Settings → MCP Servers (or Developer → Edit Config depending on your version).
Step 2: Add BlazeSQL
Add a new MCP server with the following configuration:
{ "mcpServers": { "blazesql": { "url": "https://claude.blazesql.com/mcp" } }}
Step 3: Authenticate and Query
When you first use BlazeSQL in a conversation, Claude Desktop will prompt you to sign in and select your database. After that, you can query your data just like on claude.ai.
Tips for Best Results
Be specific: Mention table or column names if you know them to help BlazeSQL find the right data faster.
Iterate naturally: Ask follow-up questions like "now break that down by region" or "only show rows from 2025."
Train your assistant: If a query returns unexpected results, correct it in the BlazeSQL app — it learns from your feedback over time.
Switching Databases
To query a different database, disconnect BlazeSQL from Claude and reconnect it. During reconnection, you'll be prompted to select a new database.
Data Privacy
BlazeSQL takes data privacy seriously:
Only database metadata (table names, column names) is stored by BlazeSQL — not your actual data
Queries are executed in real-time and results are returned directly to Claude
Your database credentials are never shared with Anthropic or Claude
Each connection is isolated to your BlazeSQL account

Troubleshooting
Can't find BlazeSQL in Claude
BlazeSQL may still be rolling out to all Claude users. Make sure you're on a Claude Pro or Team plan. If you still don't see it, check back soon or reach out to us.
Authentication errors
Try disconnecting and reconnecting. Make sure you're signing in with the same BlazeSQL account that has your databases connected.
