🔌️ Prerequisites

• MCP Client application, e.g. Claude Desktop

💾 Installation

Ensure the uv package is installed. If uncertain call

uv --version

To install uv on macOS please use brew, i.e.

brew install uv

For other operating systems, please follow the instructions in the uv official documentation.

🧠 Using the server with the Claude Desktop

To enable the Claude Desktop using the Exasol MCP server, the latter must be listed in the configuration file claude_desktop_config.json. A similar configuration file would exist for most other MCP Client applications.

To find the Claude Desktop configuration file, click on the Settings and navigate to the “Developer” tab. This section contains options for configuring MCP servers and other developer features. Click the “Edit Config” button to open the configuration file in the editor of your choice.

Add the Exasol MCP server to the list of MCP servers as shown in this configuration example.

{
    "mcpServers": {
        "exasol_db": {
            "command": "uvx",
            "args": ["exasol-mcp-server@latest"],
            "env": {
                "EXA_DSN": "my-dsn",
                "EXA_USER": "my-user-name",
                "EXA_PASSWORD": "my-password"
            }
        }
    }
}

With these settings, uv will execute the latest version of the exasol-mcp-server in an ephemeral environment, without installing it.

Alternatively, the exasol-mcp-server can be installed using the command:

uv tool install exasol-mcp-server@latest

For further details on installing and upgrading the server using uv see the uv Tools documentation.

If the server is installed, the Claude configuration file should look like this:

{
    "mcpServers": {
        "exasol_db": {
            "command": "exasol-mcp-server",
            "env": "same as above"
        }
    }
}

Please note that any changes to the Claude configuration file will only take effect after restarting Claude Desktop.

🟠 🟢 Running modes

The MCP server can be deployed either locally, as described above, or as a remote HTTP server. To run the server as a Direct HTTP Server execute the command:

exasol-mcp-server-http --host <server-host> --port <server-port>

The host defaults to 0.0.0.0.

This command provides a simple way to verify the setup for a remote MCP Server deployment. For the production environment, one might consider using an ASGI server like Unicorn. The most flexible approach is implementing a wrapper for the Exasol MCP server that will provide the desired control options. For further information and ideas, please check the HTTP Deployment in the FastMCP documentation.

Here is an example code creating the Exasol MCP server from a wrapper.

from exasol.ai.mcp.server import mcp_server

exasol_mcp = mcp_server()

🔧 Configuration settings

The server is configured using environment variables and optionally a json file. In the above example, the server is provided with the database connection parameters, all other settings left to default. For the information on how to customize server settings please see the Server Setup in the User Guide.
