What Windsurf can do with Sequel

Cascade with real data access

Windsurf's Cascade agent can now include database queries in its multi-step workflows. Ask it to check your schema, pull production data, and use it to guide code generation — all in one flow.

Data-informed development

Stop context-switching to a SQL client when you need to understand your data. Ask Cascade to query your database directly and use the results to write more accurate code and migrations.

Python analysis alongside your code

When you need statistical analysis or visualizations, Cascade can run Python through Sequel's sandbox — pandas, matplotlib, seaborn — and show results inline in the editor.

Example prompts

Everything you can ask Windsurf about your data.

Ask in plain English. Sequel turns it into a query, runs it read-only, and Windsurf hands back the answer. No SQL, no dashboards, no CSV exports.

Connect Windsurf
What you can ask Windsurf
  • What's the shape of our `users` table — columns, types, constraints?
  • Show me 10 example rows from the `transactions` table
  • How many orders were placed in the last 24 hours?
  • Which columns in our database have high NULL rates?
  • Generate a migration to add an index on `orders.created_at`

Setup

Add Sequel to Windsurf

Drop the Sequel MCP server into Windsurf, then ask it anything about your connected data. Sequel is read-only by default and shows each query before it runs.

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "sequel": {
      "serverUrl": "https://api.sequel.sh/mcp",
      "headers": {
        "Authorization": "Bearer sql_your_api_key"
      }
    }
  }
}

Install

Install Sequel MCP in Windsurf

Pick your app and Sequel installs itself: a one-click link where the client supports it, that client’s own few steps where it doesn’t. Every route signs in with your Sequel account over OAuth, so there is no API key to copy and nothing to keep in sync.

Frequently asked questions

Where does the Windsurf MCP config file go?

Place your MCP configuration at ~/.codeium/windsurf/mcp_config.json. Use the `serverUrl` key (not `url`) as shown in the config above — Windsurf uses a slightly different field name than other clients.

Does this work with both Cascade and Windsurf Chat?

Yes. Sequel tools are available in both Windsurf Chat (single-turn) and Cascade (multi-step agentic flows). Cascade is especially powerful because it can chain multiple Sequel tool calls together.

How do I verify Sequel is connected in Windsurf?

Open Windsurf settings and navigate to the MCP section. You should see 'sequel' listed as a connected server with a green status indicator. If it's red, check that your API key is correct and the URL is reachable.

Can my whole team use this setup?

Each team member should have their own Sequel API key (create them in Settings → API Keys). The MCP config file is personal (in the home directory), so each developer configures it independently.
