ClickHouse MCP Server is an integration tool that allows Model Context Protocol (MCP)-enabled applications, such as Claude Desktop, to interact with ClickHouse databases or embedded chDB engines. It provides secure endpoints for executing and managing SQL queries, listing databases and tables with pagination, and includes robust authentication as well as optional write and destructive action safeguards. Additionally, users can customize workflows by integrating custom Python middleware, making it suitable for developers and teams needing programmatic ClickHouse access via MCP.
