Oracle Database MCP server

The mcp-server-oracle project provides a Model Context Protocol server for accessing Oracle databases directly from Claude Desktop. This allows Claude to interact with your Oracle database, enabling database queries and data analysis through the chat interface.

Quickstart Setup

To integrate this Oracle MCP server with Claude Desktop, you'll need to add server configuration to your Claude Desktop settings.

Prerequisites

• UV (package manager)
• Python 3.12 or higher
• Claude Desktop application

Installation

1. Install the mcp-server-oracle package using UV:

uvx install mcp-server-oracle

2. Configure Claude Desktop by editing the configuration file:

MacOS:

~/Library/Application\ Support/Claude/claude_desktop_config.json

Windows:

%APPDATA%/Claude/claude_desktop_config.json

3. Add the following configuration to your Claude Desktop config file:

{
  "mcpServers": {
    "mcp-server-oracle": {
      "command": "uvx",
      "args": [
        "mcp-server-oracle"
      ],
      "env": {
        "ORACLE_CONNECTION_STRING": "username/password@hostname:port/service_name"
      }
    }
  }
}

Usage

Setting Up Your Oracle Connection

The ORACLE_CONNECTION_STRING environment variable needs to contain your Oracle database connection details in the format:

username/password@hostname:port/service_name

Replace these placeholders with your actual Oracle database credentials:

• username: Your Oracle database username
• password: Your Oracle database password
• hostname: The hostname or IP address of your Oracle database server
• port: The port number (typically 1521 for Oracle)
• service_name: Your Oracle service name

Using with Claude Desktop

Once configured, you can start Claude Desktop and interact with your Oracle database by asking Claude to:

• Query data from tables
• Analyze database structure
• Generate reports from database content
• Perform data analysis tasks

Claude will connect to your Oracle database using the provided credentials and can execute SQL queries on your behalf.

How to add this MCP server to Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > MCP and click "Add new global MCP server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "cursor-rules-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "cursor-rules-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explictly ask the agent to use the tool by mentioning the tool name and describing what the function does.
