How to Connect ClickHouse to Cursor

Query your ClickHouse data directly from Cursor using Sequel’s MCP server. Ask questions in plain English, with no SQL, no dashboards, and no context switching.

Short answer

Connect ClickHouse to Sequel, then add Sequel's MCP server to Cursor using the config on this page. Cursor can then query your live ClickHouse data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.

Example prompts

Everything you can ask Cursor about your ClickHouse data.

Ask in plain English — Sequel translates it into a ClickHouse query, runs it, and Cursor hands back the answer. No SQL, no dashboards, no CSV exports.

Connect to your agent
What you can ask Cursor
  • How many events did we receive per hour yesterday?
  • What's the funnel conversion rate from signup to first purchase?
  • Show me the top 10 users by event count this week
  • Which event types have increased most in the last 7 days?
  • What's the day-1 retention rate for users who signed up last month?

How it works

Three steps to get started

1

Connect ClickHouse to Sequel

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

2

Add Sequel to the agent

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

3

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"
      }
    }
  }
}

Install

Install ClickHouse MCP in Cursor

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.

Already have an MCP client?

https://api.sequel.sh/mcp

Add it as a remote (streamable HTTP) server and sign in when prompted. Skills come with it; nothing else to install. Manual setup per client

Add Sequel to Cursor

One click: the button above opens Cursor with Sequel pre-filled, and Cursor signs you in with your Sequel account. There is no key to paste.

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.
