Todo List MCP Server

A Model Context Protocol (MCP) server that provides a comprehensive API for managing todo items.

• Update todos: Modify existing tasks
• Complete todos: Mark tasks as done

3. get-todo: Get a specific todo by ID
4. update-todo: Update a todo’s title or description
5. complete-todo: Mark a todo as completed
6. delete-todo: Delete a todo
7. search-todos-by-title: Search todos by title (case-insensitive partial match)
8. search-todos-by-date: Search todos by creation date (format: YYYY-MM-DD)

Configuring with Claude for Desktop

Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "todo": {
      "command": "node",
      "args": ["/absolute/path/to/todo-list-mcp/dist/index.js"]
    }
  }
}

Cursor

• Go to “Cursor Settings” -> MCP
• Add a new MCP server with a “command” type
• Add the absolute path of the server and run it with node
• Example: node /absolute/path/to/todo-list-mcp/dist/index.js

Example Commands

When using with Claude for Desktop or Cursor, you can try:

• “Create a todo to learn MCP with a description explaining why MCP is useful”
• “List all my active todos”
• “Create a todo for tomorrow’s meeting with details about the agenda in markdown”
• “Mark my learning MCP todo as completed”
• “Summarize all my active todos”

Learning from This Project

This project is designed as an educational resource. To get the most out of it:

1. Read the GUIDE.md for a comprehensive explanation of the design
2. Study the heavily commented source code to understand implementation details
3. Use the test client to see how the server works in practice
4. Experiment with adding your own tools or extending the existing ones
