MCP
MCP (Model Context Protocol) is a standard way for agents to safely talk to tools. Anthropic created it in 2024; everyone is adopting it.
Before MCP, every agent plus every tool needed custom code. Now MCP is like USB for AI tools — one standard, works everywhere.
Three things MCP makes possible
- Plug-and-play tools across agents
- Standard permission model for every tool
- Faster building of new agent capabilities
Key terms in this lesson
The big idea: MCP is becoming the standard way agents connect to tools.
Practice this safely
Try this with a school, hobby, or family example where the stakes are low. Use the AI output as a draft you can question, not as the final answer.
- 1Ask AI to explain Model Context Protocol in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "MCP — How Agents Connect to Tools" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check API standard against a trusted source, teacher, adult, expert, or original document before you use it.
