"""
Test OAuth with Dynamic Client Registration (DCR) using Linear.

Linear supports DCR, so no manual OAuth app setup is required.
Just run this script and it will:
1. Discover OAuth metadata from Linear
2. Dynamically register a client
3. Open your browser to authorize
4. Connect to the MCP server
