Can I integrate external APIs with my plugin?

Yes, by incorporating MCP (Model Context Protocol) servers, your plugin can securely connect Claude to external databases, tools, and third-party APIs.

How do I test my plugin locally?

You can add your local directory as a marketplace using '/plugin marketplace add ./path' and then install it with '/plugin install' to verify behavior.

What are Claude event hooks used for?

Hooks like PreToolUse or PostPromptSubmit allow your plugin to react to Claude's actions, enabling automated validation, logging, or data modification.

How does plugin distribution work?

Plugins are distributed via Git repositories or local paths. They use semantic versioning and can be cataloged in a marketplace.json file for easy discovery.

What are the core components of a Claude Code plugin?

A plugin typically consists of a plugin.json metadata file, a README, and optional components like slash commands, custom agents, event hooks, and MCP servers.
