What is the Model Context Protocol (MCP) and what problem does it solve?

For AI / LLM Engineer MLOps Engineer ML Engineer

The short answer

MCP is an open protocol from Anthropic that standardizes how LLM applications discover and connect to external tools, data sources, and prompts through a common client-server interface. It replaces bespoke per-integration glue with a single protocol, so any MCP-compatible host can use any MCP server, and has been adopted across the broader ecosystem.
