Things MCP Server

This Model Context Protocol (MCP) server lets you use Claude Desktop to interact with your task management data in Things app. You can ask Claude to create tasks, analyze projects, help manage priorities, and more.

This server leverages the Things.py library and the Things URL Scheme.

Features

• Access to all major Things lists (Inbox, Today, Upcoming, etc.)
• Project and area management
• Tag operations
• Advanced search capabilities
• Recent items tracking
• Detailed item information including checklists
• Support for nested data (projects within areas, todos within projects)

Installation (for Claude Desktop)

1. Prerequisites

• Python 3.12+
• Claude Desktop
• Things 3 (“Enable Things URLs” must be turned on in Settings -> General)

2. Install uv if you haven’t already:

curl -LsSf https://astral.sh/uv/install.sh | sh

Resart your terminal afterwards.

3. Clone this repository:

git clone https://github.com/hald/things-mcp

4. Install the required Python packages:

cd things-mcp
uv venv
uv pip install -r pyproject.toml

5. Edit the Claude Desktop configuration file:

code ~/Library/Application Support/Claude/claude_desktop_config.json

Add the Things server to the mcpServers key to the configuration file (be sure to update the path to the folder where you installed these files):

{
    "mcpServers": {
        "things": {
            "command": "uv",
            "args": [
                "--directory",
                "/ABSOLUTE/PATH/TO/PARENT/FOLDER/things-mcp",
                "run",
                "things_server.py"
            ]
        }
    }
}

Restart the Claude Desktop app.

Sample Usage with Claude Desktop

• “What’s on my todo list today?”
• “Create a todo to pack for my beach vacation next week, include a packling checklist.”
• “Evaluate my current todos using the Eisenhower matrix.”
• “Help me conduct a GTD-style weekly review using Things.”

Tips

• Create a project in Claude with custom instructions that explains how you use Things and organize areas, projects, tags, etc. Tell Claude what information you want included when it creates a new task (eg asking it to include relevant details in the task description might be helpful).
• Try adding another MCP server that gives Claude access to your calendar. This will let you ask Claude to block time on your calendar for specific tasks, create todos from upcoming calendar events (eg prep for a meeting), etc.
