Integrates with ClickHouse databases to execute SQL queries and retrieve results in JSON format, enabling data analysis and exploration directly within conversation interfaces.
  1. Determine Your Clickhouse Server Credentials

    • You need to know your Clickhouse server's host address, the username, and the password required for access.
    • Optionally, have the name of the database you wish to connect to.
    • Decide if you want to enable read-only mode (recommended for extra safety—set as "true" for read-only, "false" for full access).
  2. Log in to the FastMCP Connection Interface

    • Click the “Install Now” button to add ENV values for the Clickhouse integration.
  3. Fill in the Environment Variable Fields as Follows:

    • CLICKHOUSE_HOST: Enter the address of your Clickhouse server (e.g., example.server.com).
    • CLICKHOUSE_USER: Enter your Clickhouse username (default is usually root).
    • CLICKHOUSE_PASSWORD: Enter your Clickhouse password.
    • CLICKHOUSE_DATABASE (optional): Enter the database name if you want to connect to a specific initial database.
    • CLICKHOUSE_READONLY: Set this to "true" for a read-only connection, "false" for full access (default: "false").
  4. Save the Configuration

    • Confirm the values and save the connection.

Notes:

  • These values correspond to your Clickhouse account and server—if you do not have them, contact your Clickhouse administrator.
  • No API key is required—just the server connection details above.

You can now proceed with using the Clickhouse MCP server integration in your environment.
