The article traces the evolution of LLM tool integration from basic tool use through standardized function calling to the Model Context Protocol (MCP), an open standard from Anthropic. MCP solves the N×M fragmentation problem where each LLM provider had incompatible integration formats, allowing developers to write tools once for universal deployment. Major AI companies are adopting this standard.
