What you will learn
  1. MCP standardises how AI apps discover and call tools and read resources.
  2. A server declares tools with schemas; the client decides when to call them.
  3. Least privilege and confirmation for writes keep it safe.

One protocol instead of many plugins

Every AI assistant used to need its own plugin format. The Model Context Protocol (MCP) gives them one: a server describes tools (actions), resources (readable data) and prompts, and any MCP-capable client can use them.

For a team, that means writing one integration for your internal docs or ticket system and using it from several assistants and IDEs.

In the rest of this story
  1. Tools, resources and transports
