SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill eliminates the complexity and configuration errors of connecting external services, APIs, and tools to Claude Code plugins via the Model Context Protocol, removing the need for developers to manually piece together MCP integration steps.

Core Features & Use Cases

  • Multi-Protocol MCP Support: Configure stdio, SSE, HTTP, and WebSocket MCP servers for local tools, cloud services, REST APIs, and real-time streaming use cases.
  • Secure Authentication Setup: Handle OAuth, token-based, and environment variable authentication flows without exposing sensitive credentials.
  • Use Case: A project management plugin can integrate the Asana SSE MCP server to let users create, search, and update Asana tasks directly within Claude Code without switching between applications.

Quick Start

Use the MCP Integration skill to configure a hosted SSE MCP server with automatic OAuth authentication for your plugin's configuration file.

Frequently Asked Questions about MCP Integration

FAQPage Schema
How do I configure an MCP server for a Claude Code plugin?▼

To configure an MCP server for a Claude Code plugin, you define the connection settings for local stdio, hosted SSE, HTTP, or WebSocket endpoints within your plugin configuration file to enable external service integration.

How does OAuth authentication work with hosted SSE MCP servers?▼

OAuth authentication for hosted SSE MCP servers is handled securely during configuration without exposing sensitive credentials. The setup process manages token-based authentication flows automatically for your plugin's configuration file.

Can I use environment variables for MCP server authentication in Claude Code?▼

Yes, you can use environment variables for MCP server authentication in Claude Code to ensure credential portability. The integration supports secure environment variable handling to prevent exposing sensitive authentication tokens.

What is the best way to handle MCP server lifecycle errors in Claude Code?▼

Handling MCP server lifecycle errors in Claude Code requires proper error handling configuration during server setup. The MCP integration skill provides built-in error management for connection issues across stdio, SSE, HTTP, and WebSocket protocols.

Does Claude Code support both local stdio and remote HTTP MCP servers?▼

Yes, Claude Code supports both local stdio and remote HTTP MCP servers. The multi-protocol MCP support allows configuration for local tools, cloud services, REST APIs, and real-time streaming use cases within your plugin development workflow.

Why do I need tool pre-approval configuration for MCP integrations?▼

Tool pre-approval configuration for MCP integrations is needed to securely manage which external tools can execute actions within Claude Code. This prevents unauthorized tool execution while allowing approved services to automate tasks.
