  token: ${MM_TOKEN}          # env interpolation supported
  team: engineering
  verify_ssl: true             # set false for self-signed certs

llm:
  base_url: https://api.openai.com/v1
  api_key: ${OPENAI_API_KEY}
  model: gpt-4o-mini
  verify_ssl: true

agent:
  max_iterations: 15
  total_token_budget: 200000
  max_threads_per_query: 20
