Microsoft Onedrive MCP Server By Cdata

🚀 CData's MCP Server for Microsoft OneDrive

CData's Model Context Protocol (MCP) Server enables LLMs to query live data from Microsoft OneDrive. It simplifies data access, allowing natural - language queries without SQL.

⚠️ Important Note

This project builds a read - only MCP server. For full read, write, update, delete, and action capabilities and a simplified setup, check out our free CData MCP Server for Microsoft OneDrive (beta).

🚀 Quick Start

Purpose

We created this read - only MCP Server to allow LLMs (like Claude Desktop) to query live data from Microsoft OneDrive supported by the CData JDBC Driver for Microsoft OneDrive. The CData JDBC Driver connects to Microsoft OneDrive by exposing them as relational SQL models. This server wraps that driver and makes Microsoft OneDrive data available through a simple MCP interface, so LLMs can retrieve live information by asking natural language questions — no SQL required.

Setup Guide

1. Clone the repository:

   git clone https://github.com/cdatasoftware/microsoft-onedrive-mcp-server-by-cdata.git
   cd microsoft-onedrive-mcp-server-by-cdata
   

2. Build the server:

   mvn clean install
   

   This creates the JAR file: CDataMCP-jar-with-dependencies.jar
3. Download and install the CData JDBC Driver for {source}: https://www.cdata.com/drivers/onedrive/download/jdbc
4. License the CData JDBC Driver:
   • Navigate to the lib folder in the installation directory, typically:
     • (Windows) C:\Program Files\CData\CData JDBC Driver for Microsoft OneDrive\
     • (Mac/Linux) /Applications/CData JDBC Driver for Microsoft OneDrive/
   • Run the command java -jar cdata.jdbc.onedrive.jar --license
   • Enter your name, email, and "TRIAL" (or your license key).
5. Configure your connection to the data source (Salesforce as an example):
   • Run the command java -jar cdata.jdbc.onedrive.jar to open the Connection String utility.
   • Configure the connection string and click "Test Connection"

     Note: If the data sources uses OAuth, you will need to authenticate in your browser.

   • Once successful, copy the connection string for use later.
6. Create a .prp file for your JDBC connection (e.g. microsoft-onedrive.prp) using the following properties and format:

   Prefix=onedrive
   ServerName=CDataOneDrive
   ServerVersion=1.0
   DriverPath=PATH\TO\cdata.jdbc.onedrive.jar
   DriverClass=cdata.jdbc.onedrive.OneDriveDriver
   JdbcUrl=jdbc:onedrive:InitiateOAuth=GETANDREFRESH;
   Tables=
   

Using the Server with Claude Desktop

1. Create the config file for Claude Desktop (claude_desktop_config.json) to add the new MCP server, using the format below. If the file already exists, add the entry to the mcpServers in the config file.
   • Windows

   {
       "mcpServers": {
           "{classname_dash}": {
               "command": "PATH\\TO\\java.exe",
               "args": [
                   "-jar",
                   "PATH\\TO\\CDataMCP-jar-with-dependencies.jar",
                   "PATH\\TO\\microsoft-onedrive.prp"
               ]
           }
       }
   }
   

   • Linux/Mac

   {
       "mcpServers": {
           "{classname_dash}": {
               "command": "/PATH/TO/java",
               "args": [
                   "-jar",
                   "/PATH/TO/CDataMCP-jar-with-dependencies.jar",
                   "/PATH/TO/microsoft-onedrive.prp"
               ]
           }
       }
   }
   

   If needed, copy the config file to the appropriate directory (Claude Desktop as the example).
   • Windows

   cp C:\PATH\TO\claude_desktop_config.json %APPDATA%\Claude\claude_desktop_config.json
   

   • Linux/Mac

   cp /PATH/TO/claude_desktop_config.json /Users/{user}/Library/Application\ Support/Claude/claude_desktop_config.json
   

2. Run or refresh your client (Claude Desktop).

   Note: You may need to fully exit or quit your Claude Desktop client and re - open it for the MCP Servers to appear.

Running the Server

1. Run the following command to run the MCP Server on its own

   java -jar /PATH/TO/CDataMCP-jar-with-dependencies.jar /PATH/TO/Salesforce.prp
   

   Note: The server uses stdio so can only be used with clients that run on the same machine as the server.

💻 Usage Examples

Basic Usage

Once the MCP Server is configured, the AI client will be able to use the built - in tools to read, write, update, and delete the underlying data. In general, you do not need to call the tools explicitly. Simply ask the client to answer questions about the underlying data system. For example:

• "What is the correlation between my closed won opportunities and the account industry?"
• "How many open tickets do I have in the SUPPORT project?"
• "Can you tell me what calendar events I have today?"

Tools & Descriptions

In the definitions below, {servername} refers to the name of the MCP Server in the config file (e.g. {classname_dash} above).

• {servername}_get_tables - Retrieves a list of tables available in the data source. Use the {servername}_get_columns tool to list available columns on a table. The output of the tool will be returned in CSV format, with the first line containing column headers.
• {servername}_get_columns - Retrieves a list of columns for a table. Use the {servername}_get_tables tool to get a list of available tables. The output of the tool will be returned in CSV format, with the first line containing column headers.
• {servername}_run_query - Execute a SQL SELECT query

Troubleshooting

1. If you cannot see your CData MCP Server in Claude Desktop, be sure that you have fully quit Claude Desktop (Windows: use the Task Manager, Mac: use the Activity Monitor)
2. If Claude Desktop is unable to retrieve data, be sure that you have configured your connection properly. Use the Connection String builder to create the connection string (see above) and copy the connection string into the property (.prp) file.
3. If you are having trouble connecting to your data source, contact the CData Support Team.
4. If you are having trouble using the MCP server, or have any other feedback, join the CData Community.
