How it works

Three steps to get started

Connect ClickHouse to Sequel

In your Sequel dashboard, go to Connections and add ClickHouse. 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. "How many events did we receive per hour yesterday?" — and get a real answer backed by live ClickHouse 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 ClickHouse to Cursor?

You need two things: (1) connect ClickHouse 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 ClickHouse data directly.

What ClickHouse data can Cursor access?

Cursor can access any data available through your ClickHouse 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 ClickHouse 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 ClickHouse and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to ClickHouse and generate an API key from Settings → API Keys.

Can I connect multiple ClickHouse accounts?

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