### AI overview

This article explains that MCP and APIs serve different purposes. APIs connect software systems through predefined endpoints, while MCP lets AI models discover and use tools dynamically. MCP does not replace APIs; it operates on top of existing APIs as a standardized, AI-friendly translation layer.

### Source excerpt

Ever since MCP became popular, I hear people saying "does MCP replace APIs?" Or do they both solve completely different problems? Firstly the facts: APIs connect software systems through predefined endpoints, while MCP enables AI models to discover and use tools dynamically. So, they are two different things, but can MCP replace APIs? More discussions ...
