Agent environment variables are configured in the web UI and passed to agent containers at runtime.

Managing Environment Variables

Configure environment variables through the Blink web UI:
  1. Navigate to your agent’s settings
  2. Go to Settings → Environment Variables
  3. Add, edit, or delete variables as needed
Each variable has:
  • Key - The variable name (e.g., ANTHROPIC_API_KEY)
  • Value - The variable value
  • Secret - Whether to mask the value
