Setup

OAuth Authentication

To enable OAuth authentication with TickTick, you'll need to register your app and obtain API credentials:

• Create an account on the TickTick Developer Portal
• Register a new application
• Set the OAuth redirect URL to: http://localhost:8000/callback
• Copy the generated Client ID (TICKTICK_CLIENT_ID) and Client Secret (TICKTICK_CLIENT_SECRET)

First-Time Authorization Flow

When using the TickTick MCP server for the first time:

1. You'll be prompted to authorize the application

2. A browser window will open with the TickTick login page

3. After login, you'll be asked to grant permissions

4. The access token will be displayed in the page

5. Copy this token and set it as the TICKTICK_ACCESS_TOKEN environment variable

Generate Access Token

When you need to generate a new access token (either for first-time setup or when the token expires), follow these steps:

1. Configure your credentials using one of these methods:

#### Option 1: .env file (Recommended)

Create a .env file in your project root:

TICKTICK_CLIENT_ID=""
   TICKTICK_CLIENT_SECRET=""

Then load it:

source .env

This method is recommended because:

• Credentials persist between terminal sessions
• Easier to manage multiple configurations
• Less prone to shell history leaks
• Can be easily backed up (remember to exclude from version control)

#### Option 2: Terminal Environment Variables

Use single quotes if your credentials contain special characters. Note that these variables will only persist in your current terminal session:

export TICKTICK_CLIENT_ID=''
   export TICKTICK_CLIENT_SECRET=''

2. Run the authentication command:

If using the published package:

npx @alexarevalo.ai/mcp-server-ticktick ticktick-auth

If running the MCP server locally:

npm run start:auth

The process will:

• Launch your default browser
• Direct you to TickTick's login page
• Request necessary permissions
• Generate and display your access token

3. Save the access token:

echo "TICKTICK_ACCESS_TOKEN=\"\"" >> .env
   source .env

Security Tips:

- Add .env to your .gitignore file

- Never commit credentials to version control

- Access tokens expire after 180 days - you'll need to regenerate them
