What is the Model Context Protocol (MCP)?

MCP is an open standard that allows Claude to connect to external data sources and tools, such as databases or APIs, through a structured interface.

What is a Claude Code plugin?

A Claude Code plugin is a package of specialized tools, skills, and agents that extend the functionality of the Claude CLI for specific development tasks.

How do I test my new skill locally?

You can test your plugin by running 'claude --plugin-dir ./path-to-your-plugin' and then using the 'claude plugin validate' command to ensure it meets requirements.

What are Claude Code hooks?

Hooks are event-driven triggers that allow a plugin to intercept or react to specific Claude actions, such as before a tool is used or after a response is generated.

What are the required files for a plugin?

Every plugin requires a '.claude-plugin/plugin.json' manifest file to define its identity, version, and entry points for skills and commands.
