Ibm Cloud Object Storage MCP Server By Cdata

🚀 ibm-cloud-object-storage-mcp-server-by-cdata

CData's Model Context Protocol (MCP) Server enables LLMs to query live data from IBM Cloud Object Storage, offering a simple interface for natural - language data retrieval.

🚀 Quick Start

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 IBM Cloud Object Storage (beta).

✨ Features

• Live Data Query: Allows LLMs (such as Claude Desktop) to query live data from IBM Cloud Object Storage.
• Natural Language Interface: Eliminates the need for SQL knowledge, enabling users to retrieve data by asking natural language questions.
• Relational SQL Model: The CData JDBC Driver exposes IBM Cloud Object Storage as relational SQL models, facilitating data access.

📦 Installation

1. Clone the repository

git clone https://github.com/cdatasoftware/ibm-cloud-object-storage-mcp-server-by-cdata.git
cd ibm-cloud-object-storage-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

Download the CData JDBC Driver for {source}: https://www.cdata.com/drivers/ibmcloudobjectstorage/download/jdbc

4. License the CData JDBC Driver

• Navigate to the lib folder in the installation directory:
  • (Windows) C:\Program Files\CData\CData JDBC Driver for IBM Cloud Object Storage\
  • (Mac/Linux) /Applications/CData JDBC Driver for IBM Cloud Object Storage/
• Run the command java -jar cdata.jdbc.ibmcloudobjectstorage.jar --license
• Enter your name, email, and "TRIAL" (or your license key).

5. Configure your connection to the data source

• Run the command java -jar cdata.jdbc.ibmcloudobjectstorage.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

Create a .prp file (e.g., ibm - cloud - object - storage.prp) with the following properties:

Prefix=ibmcloudobjectstorage
ServerName=CDataIBMCloudObjectStorage
ServerVersion=1.0
DriverPath=PATH\TO\cdata.jdbc.ibmcloudobjectstorage.jar
DriverClass=cdata.jdbc.ibmcloudobjectstorage.IBMCloudObjectStorageDriver
JdbcUrl=jdbc:ibmcloudobjectstorage:InitiateOAuth=GETANDREFRESH;
Tables=

💻 Usage Examples

Using the Server with Claude Desktop

1. Create the config file

Create the config file for Claude Desktop (claude_desktop_config.json) to add the new MCP server. Windows

{
    "mcpServers": {
        "{classname_dash}": {
            "command": "PATH\\TO\\java.exe",
            "args": [
                "-jar",
                "PATH\\TO\\CDataMCP-jar-with-dependencies.jar",
                "PATH\\TO\\ibm-cloud-object-storage.prp"
            ]
        }
    }
}

Linux/Mac

{
    "mcpServers": {
        "{classname_dash}": {
            "command": "/PATH/TO/java",
            "args": [
                "-jar",
                "/PATH/TO/CDataMCP-jar-with-dependencies.jar",
                "/PATH/TO/ibm-cloud-object-storage.prp"
            ]
        }
    }
}

If needed, copy the config file to the appropriate directory: 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

Run or refresh your Claude Desktop client.

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

Run the following command to run the MCP Server:

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 Details

Once the MCP Server is configured, the AI client can use the built - in tools to read, write, update, and delete the underlying data. Simply ask the client 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 will be 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 will be in CSV format, with the first line containing column headers.
• {servername}_run_query: Execute a SQL SELECT query

JSON - RPC Request Examples

If you are scripting out the requests sent to the MCP Server instead of using an AI Client (e.g., Claude), you can refer to the following JSON payload examples (following the JSON - RPC 2.0 specification) when calling the available tools.

source_get_tables

{
    "jsonrpc": "2.0",
    "id": 1,
    "method": "tools/call",
    "params": {
        "name": "source_get_tables",
        "arguments": {}
    }
}

source_get_columns

{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "tools/call",
    "params": {
        "name": "source_get_columns",
        "arguments": {
            "table":  "Account"
        }
    }
}

source_run_query

{
    "jsonrpc": "2.0",
    "id": 3,
    "method": "tools/call",
    "params": {
        "name": "source_run_query",
        "arguments": {
            "sql":  "SELECT * FROM [Account] WHERE [IsDeleted] = true"
        }
    }
}

📚 Documentation

Troubleshooting

• Server Not Visible in Claude Desktop: Ensure that you have fully quit Claude Desktop (Windows: use the Task Manager, Mac: use the Activity Monitor).
• Data Retrieval Issue: Make sure you have configured your connection properly. Use the Connection String builder to create the connection string and copy it into the property (.prp) file.
• Data Source Connection Issue: Contact the CData Support Team.
• MCP Server Usage Issue or Feedback: Join the CData Community.
