Todo MCP Server

A simple Todo application built using MCP (Model Context Protocol) Server for testing and demonstrating MCP

interactions.

Overview

This repository contains a minimal Todo application implemented as an MCP server. It allows you to:

• List all todo items
• View specific todo items
• Add new todo items
• Remove todo items
• Clear all todo items
• Create structured todo tasks with metadata

This project serves as a test bed for interacting with Model Context Protocol servers and understanding how to build and

expose functionality through the MCP protocol. For more information about the Model Context Protocol,

visit modelcontextprotocol.io.

Requirements

• Python 3.10+
• uv (Python package installer)

Installation

1. Clone the repository:

git clone https://github.com/idsulik/todo-mcp-server.git
cd todo-mcp-server

2. Install dependencies using uv:

uv pip install -e .

Adding to MCP Servers List

To add this server to your MCP servers list, use the following command:

mcp install server.py --name "Todo MCP"

This registers the server with the Claude Desktop app or other MCP-enabled applications.

Alternatively, if you want to test the server with the MCP Inspector, you can use:

mcp dev server.py

This will launch the server along with the MCP Inspector interface for easy testing and debugging.

API Usage

The server exposes the following MCP resources and tools:

Resources

1. List all todo items:

GET todo://list

2. View a specific todo item:

GET todo://view/{item_idx}

Where item_idx is the index of the item you want to view.

Prompts

1. Create a structured todo task:

create_task(task_name: str, priority: str = "medium", due_date: str = "")

This prompt helps format todo tasks with priority levels and due dates. Parameters:

• task_name: The name/description of the task
• priority: Task priority (low, medium, high)
• due_date: When the task is due (optional)

Tools

1. Add a new todo item:

add_todo(value: str)

2. Remove a todo item:

remove_todo(item_idx: int)

3. Clear all todo items:

clear_todo()

Adding to MCP Configuration Manually

If you prefer to add the server manually to your MCP configuration, you can add the following JSON to your Claude

Desktop configuration file (typically located at ~/.claude-desktop/claude_desktop_config.json on Mac/Linux or

C:\Users\YourUsername\AppData\Roaming\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "todo": {
      "command": "uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "/path/to/your/server.py"
      ]
    }
  }
}

Replace /path/to/your/server.py with the absolute path to your server.py file. Make sure to use absolute paths, not

relative paths.

Using Docker

You can also run this MCP server using Docker without installing anything locally. Add the following to your Claude Desktop configuration:

{
  "mcpServers": {
    "todo": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "idsulik/todo-mcp-server"
      ]
    }
  }
}

The Docker image will automatically pull from Docker Hub if it's not already on your system.
