AI Agents and MCPWhere to start
Read what an agent is, then what MCP is, then how it is built. The page with the tiny server shows real messages, and the security page is the one to read before you connect anything to real data.
This is an independent guide. It is not connected with Anthropic or the MCP project. This field changes quickly: statements were read on 14 November 2026 from the pages named under Sources (the MCP site shows specification version 2026-07-28 in its page addresses). The demo server and the messages are real: we ran them with the official Python SDK (mcp 2.3.0). No AI model was used for the demos.
