How to Connect ClickHouse to ChatGPT
Query your ClickHouse data directly from ChatGPT 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 ChatGPT using the config on this page. ChatGPT can then query your live ClickHouse data in plain English, with no connector code and no CSV exports. Both steps take a few minutes.
Everything you can ask ChatGPT about your ClickHouse data.
Ask in plain English — Sequel translates it into a ClickHouse query, runs it, and ChatGPT hands back the answer. No SQL, no dashboards, no CSV exports.
- 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
Connect ClickHouse to Sequel
In your Sequel dashboard, go to Connections and add ClickHouse. Sequel handles authentication and schema discovery automatically.
Add Sequel to the agent
Copy the Sequel MCP configuration into ChatGPT's settings file (shown below). Swap in your API key from Settings → API Keys.
Ask ChatGPT about your data
Restart ChatGPT and start asking questions. "How many events did we receive per hour yesterday?" — and get a real answer backed by live ClickHouse data.
Why ChatGPT
What ChatGPT does with your ClickHouse data
Real data, not hallucinations
ChatGPT with Sequel queries your actual databases in real time. Instead of guessing or making up numbers, it fetches accurate data from your connected sources and presents verified results.
Share data insights via ChatGPT conversations
Teams that already use ChatGPT for work can now use it for data questions too. Sequel handles the database access; ChatGPT handles the explanation and formatting.
Analyze data with Python in the same thread
When SQL isn't enough, Sequel's workbench tool lets ChatGPT run Python analyses — statistical summaries, charts, transformations — without leaving the conversation.
Configuration
Add Sequel to ChatGPT
Place this in ChatGPT Settings → Connectors and replace sql_your_api_key with a key from Settings → API Keys.
ChatGPT Settings → Connectors
Server URL: https://api.sequel.sh/mcp Authentication: Authorization: Bearer sql_your_api_key
Install
Install ClickHouse MCP in ChatGPT
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

Frequently asked questions
How do I connect ClickHouse to ChatGPT?
You need two things: (1) connect ClickHouse to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to ChatGPT using the setup shown above. Once both are done, ChatGPT can query your ClickHouse data directly.
What ClickHouse data can ChatGPT access?
ChatGPT 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 ChatGPT's servers?
Query results are returned to ChatGPT 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. ChatGPT will be able to query all of them.
How do I connect Sequel to ChatGPT?
In ChatGPT, go to Settings → Beta Features → Connectors (or Settings → Integrations, depending on your plan). Enter the Sequel MCP URL and your API key as the Authorization header.
Which ChatGPT plans support MCP?
MCP connector support is available on ChatGPT Plus, Team, and Enterprise plans. Check OpenAI's latest documentation for the most current availability.
Can I use Sequel with the ChatGPT API?
Yes — you can pass Sequel as a tool in any OpenAI API request by calling Sequel's MCP endpoint and converting the tool definitions to OpenAI's tool format. Contact us for guidance on this integration.
Is my data stored by OpenAI when I query through ChatGPT?
Query results are sent to OpenAI as context within your conversation and are subject to OpenAI's data handling policies. Review OpenAI's privacy policy for details. Sequel does not store query results.
How do I connect ClickHouse?
Click 'New Connection', select ClickHouse, and enter your host, port, database, username, and password. Sequel supports both HTTP and native interfaces.
Which ClickHouse versions are supported?
Sequel supports ClickHouse 21.x and above, including ClickHouse Cloud.
Can Sequel handle large ClickHouse tables?
Yes. Sequel adds LIMIT clauses by default and warns you before running queries that may trigger full table scans on large datasets. ClickHouse's columnar storage makes even large queries fast.
Does Sequel use ClickHouse-specific SQL features?
Yes. Sequel generates ClickHouse-compatible SQL including toStartOfHour, toDate, arrayJoin, and other ClickHouse functions when appropriate.
