In short
An open protocol, published by Anthropic, that defines a standard way for AI agents and LLM applications to connect to external tools, APIs, and data sources.
MCP replaces brittle per-integration "function calling" with a structured, permissioned connection layer.
Where it bites
MCP (Model Context Protocol) matters when a tool choice changes ownership, security, cost, or speed for years. The right answer depends on the operating model around it.
What to check
- What becomes easier after this choice?
- What becomes harder to reverse?
- Who maintains the integration after launch?
