【MCP Server】Sage 300 × 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 Sage 300, configuring the connection to Sage 300, 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 Sage 300
2. Configure the connection to Sage 300
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 Sage 300.
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 Sage 300.

Step 2: Configure the connection to Sage 300

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. "cdatasage300") 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 Sage 300

   Sage 300 には、Sage 300 Web API で通信するための初期設定が必要となるます。

   • Sage 300 のユーザー向けのセキュリティグループを設定します。Sage 300 のユーザーに、Security Groups の下にあるbSage 300 Web API オプションへのアクセスを付与します（各モジュール毎に必要です）。
   • /Online/Web と/Online/WebApi フォルダ内のweb.config ファイルを両方編集して、AllowWebApiAccessForAdmin のキーを true 設定します。webAPI アプリプールを再起動すると設定が反映されます。
   • ユーザーアクセスを設定したら、https://server/Sage300WebApi/ をクリックして、web API へのアクセスを確認してください。

   Basic 認証を使用してSage 300 へ認証します。

   Basic 認証を使用して接続する

   Sage 300 に認証するには、次のプロパティを入力してください。プロバイダーは、クッキーを使用してSage 300 が開いたセッションを再利用することに注意してください。 そのため、資格情報はセッションを開く最初のリクエストでのみ使用されます。その後は、Sage 300 が返すクッキーを認証に使用します。

   • Url：Sage 300 をホストするサーバーのURL に設定します。Sage 300 Web API 用のURL を次のように作成してください。 {protocol}://{host-application-path}/v{version}/{tenant}/ 例えば、 http://localhost/Sage300WebApi/v1.0/-/ です。
   • User：アカウントのユーザー名に設定します。
   • Password：アカウントのパスワードに設定します。

   Enter the appropriate connection properties in the configuration wizard.

   
5. Click "Connect" to authenticate with Sage 300.
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 Sage 300 のデータ

Now that we have installed the CData MCP Server and configured a connection, we are ready to start with Sage 300 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 Sage 300 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 Sage 300 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.
