APIs and MCPs both let systems communicate, but they serve different audiences. APIs are built for developers to connect software, while the Model Context Protocol (MCP) is built for AI models to safely use tools and access data without executing unsafe code. MCP acts as a controlled bridge — defining tools, schemas, and permissions so AI can interact with systems securely. While APIs connect machines, MCP connects intelligence to machines, introducing a safer, structured layer for the future of AI integration.
