ClickHouse MCP server (official)
MCP serverExplore ClickHouse databases and run analytical SQL, read-only by default, plus an optional embedded chDB engine.
ClickHouse's server lists databases and tables and runs SELECT queries against a ClickHouse or ClickHouse Cloud service; it can also query files and URLs through embedded chDB. Queries run read-only unless you set CLICKHOUSE_ALLOW_WRITE_ACCESS=true. Credentials come from CLICKHOUSE_* environment variables. Great for ad-hoc analytics over large event tables and for letting an agent answer product-data questions without a BI tool.
Try asking:
- "What were daily active users for the last 30 days from the 'events' table?"
- "Show the schema of every table in the 'analytics' database."
- "Which countries had the biggest week-over-week change in signups?"
