Custom Actions

MCP Config Onyx offers flexible options for configuring both custom Actions and their associated authentication. Admins can choose to:
  • Use a single shared authentication, giving all users the same level of access to Actions.
  • Require each user to complete their own authentication flow, so Actions respect individual user permissions.
Onyx supports both token-based authentication and OAuth. MCP Auth
