Todo MCP Server: Enhancing AI Application Workflow Integration

Overview: What is Todo MCP Server?

Todo MCP Server is a straightforward yet powerful implementation of an MCP (Model Context Protocol) server tailored for managing todo items with SQLite database storage. This server provides a robust foundation for integrating AI applications with specific data sources, enabling seamless communication and operation within broader AI workflows.

🔧 Core Features & MCP Capabilities

The Todo MCP Server includes essential functionalities such as adding new todo items, listing all todo items, and removing todo items by their unique IDs. These operations are designed to align with the MCP protocol, ensuring compatibility with various external applications and tools.

Add New Todo Items

To add a new task to your todo list, utilize the add-todo command with a specified text parameter. This feature is pivotal for maintaining up-to-date and relevant data within AI workflows where real-time updates are crucial.

List All Todo Items

The get-todos command allows you to retrieve all currently stored todo items in your database. This function supports dynamic and efficient retrieval of information, essential for applications requiring real-time updates or historical context.

Remove Todo Items by ID

By employing the remove-todo command along with a unique identifier, you can efficiently manage your data structure. This capability ensures that outdated or irrelevant tasks are removed promptly, maintaining optimal performance and scalability.

⚙️ MCP Architecture & Protocol Implementation

This Todo MCP Server leverages modern technologies like TypeScript for type safety and maintainability, and better-sqlite3 for efficient SQLite database operations. The server's architecture is built around the MCP protocol, ensuring seamless interaction with other AI applications through a standardized method of communication.

Data Storage

The application utilizes SQLite as its primary storage mechanism. By default, the database file resides at C:/todos/todos.db. However, this location can be easily adjusted by modifying the DB_LOCATION variable in the src/database.ts.

const DB_LOCATION = "C:/todos"; // Examples include windows paths, macOS path joining, and Linux home directory

Command-Line Tools

The following tools are available for interacting with the server:

• add-todo: Adds a new todo item.

  • Parameters: text (string).
  • Example Usage:

    add-todo(text: "Buy groceries")
    

• get-todos: Lists all todo items.

  • No additional parameters required.

• remove-todo: Removes a specific todo item by its ID.

  • Parameters: id (number).
  • Example Usage:

    remove-todo(id: 1)
    

🚀 Getting Started with Installation

Step-by-Step Setup Instructions

To get the Todo MCP Server up and running, follow these instructions:

1. Install Dependencies:

   npm install
   

2. Configure Database Location (Optional): Open src/database.ts to adjust the DB_LOCATION variable for your preferred data storage location.

3. Build the Project:

   npm run build
   

💡 Key Use Cases in AI Workflows

Use Case 1: Daily Task Management

Imagine building an application that integrates with a calendar or scheduling tool, allowing users to dynamically add tasks and manage their todo lists from within their AI application. The Todo MCP Server provides the backbone for real-time task updates, ensuring seamless integration.

Use Case 2: Automated Data Feeds

Utilize the get-todos API endpoint in an intelligent assistant that needs to maintain a real-time feed of important items. For instance, integrating this into a financial management application where transactions or events are frequently updated can enhance user experience and data accuracy.

🔌 Integration with MCP Clients

The Todo MCP Server is compatible with multiple MCP clients, including:

• Claude Desktop: Full support for commands like adding, listing, and removing todo items.
• Continue: Offers full support similar to Claude Desktop.
• Cursor: Compatible only as a tool provider without prompt or resource management compatibility.

📊 Performance & Compatibility Matrix

The Todo MCP Server boasts excellent performance and compatibility across different environments. The use of better-sqlite3 ensures efficient data management, while TypeScript provides robust type safety for easy development.

Example Configuration Code Sample

Here is an example configuration snippet to integrate the Todo MCP Server into a larger application:

{
  "mcpServers": {
    "[server-name]": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-todo"],
      "env": {
        "API_KEY": "your-api-key"
      }
    }
  }
}

🛠️ Advanced Configuration & Security

Configuration Options

Customize the server according to your needs by modifying the configuration files and environment variables.

Security Best Practices

Ensure that sensitive information, such as API keys, is securely managed. Utilize secure methods for storing and transmitting credentials to prevent unauthorized access.

❓ Frequently Asked Questions (FAQ)

1. Q: Is there a limit to the number of todo items that can be stored?

   • A: There is no hard limit imposed by this server but the SQLite database may have its own limitations which could affect storage capacity.

2. Q: Can other applications besides those listed in the compatibility matrix use the Todo MCP Server?

   • A: While primarily designed with specific clients in mind, custom modifications and configurations might allow integration with additional tools or applications.

3. Q: How does the Todo MCP Server ensure data integrity during database operations?

   • A: This server uses better-sqlite3 for managing SQLite databases, which provides robust transactional support to maintain data integrity.

4. Q: Is there a maintenance schedule for the database updates within the Todo MCP Server?

   • A: Automatic creation and management of the database ensure that it is always up-to-date without requiring manual intervention, but regular backups are recommended for persistent storage needs.

5. Q: Can multiple users access and modify their todo lists simultaneously through different clients?

   • A: The Todo MCP Server supports concurrent operations to some extent, ensuring that no two users can overwrite each other's data during the same transaction window.
