Employee Leave Manager MCP server

This MCP server provides a tool for managing employee leave balances, applications, and history. The server is exposed via OpenAPI and integrates seamlessly with Open WebUI for an intuitive user experience.

Prerequisites

• Windows 10 or later
• Docker Desktop for Windows (available from Docker Desktop for Windows)

Installation

Install Ollama

1. Download the installer from Ollama Download
2. Run OllamaSetup.exe and follow the installation prompts
3. After installation, Ollama runs as a background service at http://localhost:11434
4. If Ollama is not already running, start it with:

ollama serve

Verify Ollama Installation

Check the installed version:

ollama --version

Pull the Required Model

Pull the default deepseek-r1 model:

ollama pull deepseek-r1

Verify the model was installed:

ollama list

Run Open WebUI and MCP Server

1. Clone the repository:

git clone https://github.com/ahmad-act/Local-AI-with-Ollama-Open-WebUI-MCP-on-Windows.git
cd Local-AI-with-Ollama-Open-WebUI-MCP-on-Windows

2. Launch both services with Docker Compose:

docker-compose up --build

This will:

• Start the Leave Manager (MCP Server) on port 8000
• Launch Open WebUI at http://localhost:3000

Usage

Add MCP Tools to Open WebUI

1. Open http://localhost:3000 in your browser
2. Click the Profile Icon and navigate to Settings
3. Select the Tools menu and click the Add (+) Button
4. Add a new tool by entering the URL: http://localhost:8000/

Example Prompts

• Check Leave Balance:

Check how many leave days are left for employee E001

• Apply for Leave:

Apply for leave for employee E001 from August 10 to August 15

• View Leave History:

What's the leave history of E001?

• Personalized Greeting:

Greet me as Alice

Troubleshooting

• Ollama not running: Ensure the service is active (ollama serve) and check http://localhost:11434
• Docker issues: Verify Docker Desktop is running and you have sufficient disk space
• Model not found: Confirm the deepseek-r1 model is listed with ollama list
• Port conflicts: Ensure ports 11434, 3000, and 8000 are free

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 "employee-leave-manager" '{"command":"docker","args":["compose","up","--build"]}'

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": {
        "employee-leave-manager": {
            "command": "docker",
            "args": [
                "compose",
                "up",
                "--build"
            ]
        }
    }
}

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": {
        "employee-leave-manager": {
            "command": "docker",
            "args": [
                "compose",
                "up",
                "--build"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
