Agency Marketplace — Claude Code Plugins & Skills

Agency Marketplace is a collection of Claude Code plugins and skills built by DevKind. Each plugin bundles domain-specific AI agent skills you can install into Claude Code in one command. Some plugins also ship MCP servers (Model Context Protocol) for live tool-use capabilities -- for example, the security plugin runs WhatWeb via Docker as an MCP server.
