What is MCP (Model Context Protocol)?
Anthropic's standard for LLMs to discover and invoke external tools.

In depth
MCP (Model Context Protocol) is Anthropic's standard that lets LLMs discover and call external tools and services in a standardized way. An MCP server exposes tools (e.g., "buy airline ticket", "check inventory"), and Claude or other LLMs can invoke them. MCP is foundational to agentic systems because it decouples model capability from business logic. Many Category A and B agents are built on MCP.
