Before getting started with Task Master, you'll need to set up your API keys. There are a couple of ways to do this depending on whether you're using the CLI or working inside MCP. It's also a good time to start getting familiar with the other configuration options available — even if you don’t need to adjust them yet, knowing what’s possible will help down the line.
## API Key Setup
Task Master uses environment variables to securely store provider API keys and optional endpoint URLs.
### MCP Usage: mcp.json file
For MCP/Cursor usage: Configure keys in the env section of your .cursor/mcp.json file.
# Google Vertex AI Configuration (Required if using 'vertex' provider)
# VERTEX_PROJECT_ID=your-gcp-project-id
```
## What Else Can Be Configured?
The main configuration file (`.taskmaster/config.json`) allows you to control nearly every aspect of Task Master’s behavior. Here’s a high-level look at what you can customize:
<Tip>
You don’t need to configure everything up front. Most settings can be left as defaults or updated later as your workflow evolves.
