MCP in a Minute

Model Context Protocol: servers, tools, permissions, and how coding agents use them.

• beginnerWhat MCP isMCP (Model Context Protocol) is a standard way for AI clients to connect to external tools and data through servers.
• intermediateTools and resourcesIn MCP, tools are actions the model can invoke; resources are data the model can read.
• intermediateLocal vs remote serversLocal MCP servers run near your machine; remote servers expose tools over the network—trust and latency differ.
• intermediatePermissions and securityMCP security is mostly about which servers you trust, which tools they expose, and what those tools can reach.
