Connect ClickHouse to Windsurf
Query your ClickHouse data directly from Windsurf using Sequel’s MCP server. Ask questions in plain English — no SQL, no dashboards, no context switching.
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 Windsurf's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask Windsurf about your data
Restart Windsurf 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 Windsurf
Place this in ~/.codeium/windsurf/mcp_config.json and replace sql_your_api_key with a key from Settings → API Keys.

Questions you can ask Windsurf
Frequently asked questions
How do I connect ClickHouse to Windsurf?
You need two things: (1) connect ClickHouse to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Windsurf using the setup shown above. Once both are done, Windsurf can query your ClickHouse data directly.
What ClickHouse data can Windsurf access?
Windsurf 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 Windsurf's servers?
Query results are returned to Windsurf 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. Windsurf will be able to query all of them.
