【MCP Server】SQL Server × Claude Desktop 連携ガイド | AI でデータを徹底活用

Model Context Protocol (MCP) is an emerging, open-source standard for connecting LLMs with external services and data sources. Through MCP Servers, AI clients can perform actions like opening Jira tickets, posting Slack messages, committing GitHub branches and more. With CData MCP Servers, these capabilities expand exponentially.

In this article, we guide the reader through installing the CData MCP Server for SQL Server, configuring the connection to SQL Server, and asking questions of the data in Claude Desktop.

Prerequisites

You need to download Claude Desktop (download) and create an account before continuing.

Overview

Here's a quick overview of the steps:

1. Download and install the CData MCP Server for SQL Server
2. Configure the connection to SQL Server
3. Ask questions about the data in Claude Desktop

Step 1: Download and install the CData MCP Server

1. To begin, navigate to https://www.cdata.com/solutions/mcp/connectors and download the CData MCP Server for SQL Server.
2. Find and double-click the installer to begin the installation.
3. Follow the prompts to complete the installation.

When the installation is complete, you are ready to configure your MCP Server by connecting to SQL Server.

Step 2: Configure the connection to SQL Server

1. After installation, the CData MCP Server configuration wizard should open automatically.

   NOTE: If the wizard does not open automatically, search for "CData MCP Server" in the Windows search bar and double-click the application.

2. Click the dropdown menu in MCP Configuration > Configuration Name and select ""
3. Name the configuration (e.g. "cdatasql") and click "OK."

   NOTE: This name is used as the name for the MCP server and as the prefix for all of the MCP Server's tools.

   

4. Connecting to SQL Server

   SQL Server 接続プロパティの取得・設定方法

   Microsoft SQL Server への接続には以下を入力します。

   • Server: SQL Server が稼働するサーバー名。
   • User: SQL Server に接続するユーザー名。
   • Password: 接続するユーザーのパスワード。
   • Database: SQL Server データベース名。

   Azure SQL Server およびAzure Data Warehouse への接続

   Azure SQL Server およびAzure Data Warehouse には以下の接続プロパティを入力して接続します:

   • Server: Azure 上のサーバー。Azure ポータルの「SQL databases」（もしくは「SQL data warehouses」）-> データベースを選択 -> 「Overview」-> 「Server name」で確認が可能です。
   • User: Azure に認証するユーザー名。
   • Password: 認証するユーザーのパスワード。
   • Database: Azure ポータルでSQL databases (or SQL warehouses) ページに表示されるデータベース名。

   Enter the appropriate connection properties in the configuration wizard.

   
5. Click "Connect" to authenticate with SQL Server.
6. Finally, click "Save Configuration" to save the MCP server.

   NOTE: This saves the configuration details to a separate file and updates the Claude Desktop configuration file (claude_desktop_config.json) to start the CData MCP Server when the Claude Desktop client starts.

With the CData MCP Server configured, you are ready to start asking questions of your live data from Claude.

Step 3: Ask AI for answers from live SQL Server のデータ

Now that we have installed the CData MCP Server and configured a connection, we are ready to start with SQL Server のデータ in Claude Desktop.

1. Open Claude Desktop. It may take a moment for the MCP Servers to start, but you will see the list of servers and tools available in the Claude interface (look for the settings icon below the prompt bar).

   You can individually enable and disable specific tools by clicking on the server name.

2. Now that you have connected, you can ask Claude questions about the SQL Server のデータ. For example: "Can you give me a quantitative analysis about my closed-won opportunities by industry?"

   NOTE: Claude may need to explore the SQL Server のデータ to make sense of it before it can begin answering questions of the data. The tabular model presented by CData alongside the database tools available simplify the data exploration and analysis for an LLM.
