TaskWarrior MCP server

This MCP server provides an interface for interacting with TaskWarrior through the Model Context Protocol. It allows AI assistants like Claude to view, filter, add, and complete your TaskWarrior tasks directly through a standardized API.

Installation

Install the MCP server package globally using npm:

npm install -g mcp-server-taskwarrior

Prerequisites

This server requires TaskWarrior to be installed and configured on your system as it runs your local task binary. If you don't have TaskWarrior installed:

• On Debian/Ubuntu: sudo apt install taskwarrior
• On macOS: brew install task
• On other systems: Visit TaskWarrior's official site for installation instructions

Configuration

Claude Desktop Integration

To use this server with Claude Desktop, add the following to your claude_desktop_config.json file:

{
  "mcpServers": {
    "taskwarrior": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-server-taskwarrior"
      ]
    }
  }
}

Available Tools

Viewing Tasks

The get_next_tasks tool retrieves all pending tasks with optional filtering capabilities:

• Filter by project: project:work
• Filter by tags: +home, +urgent

Adding Tasks

The add_task tool creates new tasks with these parameters:

• description: Task description text (required)
• due: Due date as ISO timestamp (optional)
• priority: "H", "M", or "L" for High, Medium, or Low (optional)
• project: Project name (lowercase with dots, e.g., "home.maintenance") (optional)
• tags: Array of tags (lowercase) (optional)

Completing Tasks

The mark_task_done tool marks tasks as completed by ID.

Warning: This currently uses task id which can change when tasks are added or deleted. Future versions will use UUID instead.

Example Usage

Here are some examples of how you might interact with the server through Claude:

Viewing Tasks

• "Show me all my pending tasks"
• "What tasks do I have for the 'work' project?"
• "List tasks tagged with 'urgent'"

Adding Tasks

• "Add a task: Buy groceries by tomorrow, high priority"
• "Create a new task to call John, due next Tuesday, tag as personal"
• "Add 'fix the leaky faucet' to my home.maintenance project"

Completing Tasks

• "Mark task 3 as complete"
• "I've finished the 'send email' task"

The server translates these requests into the appropriate TaskWarrior commands, such as task add priority:H Call my sister or task done 1.

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 "taskwarrior" '{"command":"npx","args":["-y","mcp-server-taskwarrior"]}'

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": {
        "taskwarrior": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-server-taskwarrior"
            ]
        }
    }
}

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": {
        "taskwarrior": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-server-taskwarrior"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
