MCP Explained: The Protocol Powering AI Agents

Short summary

An introductory explainer on the Model Context Protocol (MCP), a communication standard that lets AI models discover and use external tools, APIs, and data sources through a common interface. MCP involves three participants: the AI client, MCP servers that expose capabilities, and structured tool definitions. The article covers why MCP matters for reducing per-integration engineering effort and how typical client-server interactions work.

• •MCP is a standard protocol for AI models to discover and invoke external tools
• •Three participants: AI client, MCP server, and structured tool definitions
• •Eliminates need for custom per-model, per-tool integrations
• •Covers tool discovery, schema exchange, execution, and structured results
