Things

Things MCP enables Claude Desktop and Claude Code to interact with Things 3 on macOS, letting you create, update, list, navigate, and search Things items directly from your preferred MCP client running locally or remotely.

How to use

You connect an MCP client to this server to manage Things 3 data. Use creation tools to add to‑dos and projects, reading tools to list and inspect items, and navigation tools to open specific lists or items. Update operations require authentication, so you can modify existing items after providing your Things auth token.

How to install

Prerequisites: you need macOS with Things 3 installed and Node.js 18 or later. Ensure Things URLs are enabled in Things settings.

# Quick start (recommended)
npx github:hildersantos/things-mcp

# Manual installation
# 1) Clone the repository
git clone https://github.com/hildersantos/things-mcp.git
cd things-mcp

# 2) Install dependencies
npm install

# 3) Build the project
npm run build

# 4) Start the server
npm start

Configuration and usage notes

Configure Claude Desktop to connect to the Things MCP server by adding a server entry with the appropriate command and environment variables. You will provide your Things auth token to enable update operations.

{
  "mcpServers": {
    "things-mcp": {
      "command": "npx",
      "args": ["github:hildersantos/things-mcp"],
      "env": {
        "THINGS_AUTH_TOKEN": "your-token-here"
      }
    }
  }
}

Security and permissions

On first use, macOS may ask for permission to control Things. Grant this permission to allow the MCP server to perform actions in Things. Ensure your THINGS_AUTH_TOKEN is kept secure and not exposed in client configurations.
