Datafocus MCP server

FOCUS DATA MCP Server provides a Model Context Protocol server that enables AI assistants to directly query data results. Users can obtain data from DataFocus using natural language, making data access more intuitive and efficient.

Prerequisites

• JDK 23 or higher. Download from Oracle's website
• Gradle 8.12 or higher. Download from Gradle's website
• A DataFocus account to obtain your bearer token:
  1. Register an account at DataFocus
  2. Create an application
  3. Enter the application
  4. Navigate to Admin → Interface authentication → Bearer Token → New Bearer Token

Installation

1. Clone the repository:

git clone https://github.com/FocusSearch/focus_mcp_data.git
cd focus_mcp_data

2. Build the server:

gradle clean
gradle bootJar

The compiled JAR file will be available at: build/libs/focus_mcp_data.jar

MCP Configuration

Add the server to your MCP settings file (typically located at ~/AppData/Roaming/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json):

{
  "mcpServers": {
    "focus_mcp_data": {
      "command": "java",
      "args": [
        "-jar",
        "path/to/focus_mcp_data/focus_mcp_data.jar"
      ],
      "autoApprove": [
        "tableList",
        "gptText2DataInit",
        "gptText2DataData"
      ]
    }
  }
}

{
  "errCode": 0,
  "exception": "",
  "msgParams": null,
  "promptMsg": null,
  "success": true,
  "data": {
    // Response data will appear here
  }
}

Usage in Visual Studio Code with Cline

1. Install the Cline plugin in VS Code
2. Configure the MCP server as described above
3. Using the tools:

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "focus_mcp_data" '{"command":"java","args":["-jar","path/to/focus_mcp_data/focus_mcp_data.jar"],"autoApprove":["tableList","gptText2DataInit","gptText2DataData"]}'

See the official Claude Code MCP documentation for more details.

For 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 > Tools & Integrations and click "New MCP Server".

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

{
    "mcpServers": {
        "focus_mcp_data": {
            "command": "java",
            "args": [
                "-jar",
                "path/to/focus_mcp_data/focus_mcp_data.jar"
            ],
            "autoApprove": [
                "tableList",
                "gptText2DataInit",
                "gptText2DataData"
            ]
        }
    }
}

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 explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "focus_mcp_data": {
            "command": "java",
            "args": [
                "-jar",
                "path/to/focus_mcp_data/focus_mcp_data.jar"
            ],
            "autoApprove": [
                "tableList",
                "gptText2DataInit",
                "gptText2DataData"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
