The article compares using REST APIs versus MCP servers for AI agents needing to process emails, such as for OTP codes or verification links. While both methods are functional, MCP servers are generally preferred for agents within environments like Claude Code or Cursor due to their simplified tool invocation and reduced complexity for the agent. REST APIs require the agent to manage HTTP calls, polling, and response parsing, consuming more context tokens and increasing potential failure points, whereas MCP abstracts these details away. AI
