FAQPage Schema
How do I structure a Claude Code plugin for the marketplace?▼

A Claude Code plugin requires a root plugin.json manifest file defining metadata, optional .mcp.json for MCP server configuration, and organized component directories (commands/, skills/, hooks/). The structure ensures valid JSON/Markdown files and marketplace compatibility.

What goes in a plugin.json manifest file?▼

plugin.json contains plugin metadata, version, description, and component references. It defines the plugin's identity and structure for Claude Code to recognize and load the plugin correctly.

How do I register my plugin in the marketplace?▼

Add a valid entry to marketplace.json with plugin details and metadata. Ensure all JSON files are valid and the plugin directory follows the required structure with proper manifests and documentation.

Do I need an MCP configuration file for my Claude Code plugin?▼

An .mcp.json file is optional and used for MCP server configuration. Include it only if your plugin implements MCP server functionality; standard plugins need only plugin.json.

Can I automate plugin creation and marketplace registration?▼

Yes. This workflow automates directory scaffolding, manifest generation, README creation, and marketplace entry. It ensures plugins meet functional and technical requirements end-to-end.
