Official ClickHouse MCP server for schema discovery and analytics SQL queries against ClickHouse.
The official ClickHouse MCP server (ClickHouse/mcp-clickhouse) lets agents discover schemas and run SQL queries against ClickHouse and ClickHouse Cloud. It is open source under Apache-2.0 and runs locally over stdio. Designed for analytics and exploratory querying of large columnar datasets.
Strengths
- Official, first-party server open source under Apache-2.0
- Built for ClickHouse's analytics SQL and columnar performance
- Works with both self-hosted ClickHouse and ClickHouse Cloud
Tradeoffs
- ClickHouse-specific — not a general SQL server
- Query access should be scoped to read-only roles for agent safety
