How it works

Three steps to get started

In your Sequel dashboard, go to Connections and add Polar. Sequel handles authentication and schema discovery automatically.

Add the MCP config

Copy the Sequel MCP configuration into Cursor's settings file (shown below). Swap in your API key from Settings → API Keys.

Ask Cursor about your data

Restart Cursor and start asking questions. "What's our MRR trend over the last six months?" — and get a real answer backed by live Polar data.

Configuration

Add Sequel to Cursor

Place this in .cursor/mcp.json and replace sql_your_api_key with a key from Settings → API Keys.

.cursor/mcp.json

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

Frequently asked questions

How do I connect Polar to Cursor?

You need two things: (1) connect Polar to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Cursor using the setup shown above. Once both are done, Cursor can query your Polar data directly.

What Polar data can Cursor access?

Cursor can access any data available through your Polar 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 Polar data sent to Cursor's servers?

Query results are returned to Cursor 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 Polar and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to Polar and generate an API key from Settings → API Keys.

Can I connect multiple Polar accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple Polar accounts or properties, add each as a separate connection in Sequel. Cursor will be able to query all of them.
