glossary / MCP server

What is MCP server?

An MCP (Model Context Protocol) server exposes tools, resources, and prompts that an AI agent can discover and call over a standard protocol.

Agents connect, read the server's tools/list (or server/discover in 2026-07), and invoke tools by name with a JSON payload. Reliability of a given MCP server varies and changes over time — which is why agents check it before calling.
