A guide to APIs, MCPs, and MCP Gateways

Key points

  • APIs facilitate software-to-software communication; MCPs allow LLMs to access data and tools in a structured way.
  • MCP servers expose three capabilities: tools, resources, and prompt templates.
  • MCPs are not simple API wrappers; they reduce token waste by returning only needed data.
  • Use MCPs for AI with variable queries, APIs for deterministic app-to-app communication; gateways manage security but are perimeter defenses.
