Anthropic - Claude Certified Developer - Foundations Study Guide

8: Tools and MCPs

This chapter turns Claude from a text generator into an agent that reaches external systems through tools and Model Context Protocol servers. It covers tool definition and the agentic dispatch loop, the authoring and transports of MCP servers, and the selection logic that decides whether a given capability belongs in a built-in tool, a custom tool, a Skill, or an MCP server.
