SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

This Skill simplifies the integration of external services and APIs into Claude Code plugins by providing a standardized way to define and manage Model Context Protocol (MCP) servers.

Core Features & Use Cases

  • Connect to diverse services: Supports stdio, SSE, HTTP, and WebSocket protocols for seamless integration with databases, APIs, and real-time data streams.
  • Automated setup and management: MCP servers can be bundled with plugins for automatic startup and managed by Claude Code.
  • Use Case: A plugin needs to access a company's internal database and a real-time stock ticker API. This Skill allows the plugin developer to configure both as MCP servers, making their tools available within Claude Code without complex custom integration code.

Quick Start

Configure your MCP server by adding a .mcp.json file to your plugin root.
