Why an MCP tool beats a script your AI can't read #MCP

Your script already works, but only an MCP tool can describe itself. A script cannot say its own name or what it needs, so you explain it every time. A tool sends back a list with its name, a plain sentence and its input shape. So the AI picks it by itself and nobody writes a prompt to explain it. Have a script you keep explaining to your AI? Tell me in one line what it does. Source: https://genaiunplugged.substack.com/p/the-three-superpowers-of-mcp-tools #Shorts #MCP #AITools
