SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Claude Code plugins historically struggle to access external tools and services. MCP integration unifies external capabilities by exposing them as MCP tools, enabling seamless automation and orchestration across services.

Core Features & Use Cases

  • Unified tool access: discover and expose MCP tools from stdio, SSE, HTTP, or WS servers within Claude Code.
  • Secure authentication: supports OAuth, token-based, and environment-variable credentials with automatic handling.
  • Flexible deployment: configure via .mcp.json at plugin root or plugin.json mcpServers block; supports lifecycle management and multi-server workflows.
  • Use cases include building cross-service automations, composing multi-tool workflows, and enabling autonomous agents to orchestrate external services.

Quick Start

Add a MCP configuration by creating a .mcp.json at the plugin root or adding an mcpServers entry to plugin.json, then verify available tools with the /mcp command.

Frequently Asked Questions about MCP Integration

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I connect external MCP servers to Claude Code plugins?

You connect external MCP servers to Claude Code plugins by configuring server details in a .mcp.json file at the plugin root or within the plugin.json mcpServers block, allowing the plugin to discover and expose external services as tools.

What is Model Context Protocol integration used for?

Model Context Protocol integration is used to expose external services as tools within Claude Code, unifying external capabilities to enable seamless cross-service automation and multi-tool workflow orchestration for autonomous agents.

Does MCP integration work with hosted SSE and WebSocket services?

Yes, MCP integration works with hosted SSE and WebSocket services. It supports local stdio MCP servers, hosted SSE/HTTP services, and WebSocket tools, providing unified tool access and auto-discovery via the /mcp command.

How do I configure authentication for MCP servers in Claude Code?

You configure authentication for MCP servers using environment-variable-based credentials. The integration supports OAuth, token-based, and environment-variable credentials with automatic handling to ensure secure and reliable operation.

How do I discover available MCP tools after configuring servers?

You discover available MCP tools by running the /mcp command after configuring your servers. This verifies the server configuration and lists the documented tool schemas exposed by your local stdio, SSE, HTTP, or WebSocket services.
