Connect to and query live Sage 300 Data in Claude Desktop using the CData MCP Server.
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:
- Download and install the CData MCP Server for Sage 300
- Configure the connection to Sage 300
- Ask questions about the data in Claude Desktop
Step 1: Download and install the CData MCP Server
- To begin, navigate to https://www.cdata.com/solutions/mcp/connectors and download the CData MCP Server for Sage 300.
- Find and double-click the installer to begin the installation.
- 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
- 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.

- Click the dropdown menu in MCP Configuration > Configuration Name and select "
"
- 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.
Connecting to Sage 300
Sage 300 requires some initial setup in order to communicate over the Sage 300 Web API.
- Set up the security groups for the Sage 300 user. Give the Sage 300 user access to the
option under Security Groups (per each module required). - Edit both web.config files in the /Online/Web and /Online/WebApi folders; change the key AllowWebApiAccessForAdmin to true. Restart the webAPI app-pool for the settings to take.
- Once the user access is configured, click https://server/Sage300WebApi/ to ensure access to the web API.
Authenticate to Sage 300 using Basic authentication.
Connect Using Basic Authentication
You must provide values for the following properties to successfully authenticate to Sage 300. Note that the provider reuses the session opened by Sage 300 using cookies. This means that your credentials are used only on the first request to open the session. After that, cookies returned from Sage 300 are used for authentication.
- Url: Set this to the url of the server hosting Sage 300. Construct a URL for the Sage 300 Web API as follows: {protocol}://{host-application-path}/v{version}/{tenant}/ For example, http://localhost/Sage300WebApi/v1.0/-/.
- User: Set this to the username of your account.
- Password: Set this to the password of your account.
Enter the appropriate connection properties in the configuration wizard.
- Set up the security groups for the Sage 300 user. Give the Sage 300 user access to the
- Click "Connect" to authenticate with Sage 300.
- 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 data
Now that we have installed the CData MCP Server and configured a connection, we are ready to start with Sage 300 data in Claude Desktop.
- 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.
- Now that you have connected, you can ask Claude questions about the Sage 300 data. 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 data 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.
