FAQPage Schema
How do I connect external tools to Claude Code using the Model Context Protocol?▼

MCP integration enables Claude Code plugins to expose external services as MCP tools via the Model Context Protocol. You can connect databases, cloud services, or custom APIs by configuring an MCP server at your plugin root and using the /mcp command to discover available tools.

What transport protocols are supported for MCP servers in Claude Code plugins?▼

MCP servers support stdio, SSE, HTTP, and WebSocket transport protocols, allowing you to connect local tooling, hosted services, REST APIs, and real-time streams within your Claude Code plugin workflows.

How do I discover and register MCP tools in a Claude Code plugin?▼

You can discover and register MCP tools by running the /mcp command in Claude Code. This lists all available tools exposed by your configured MCP servers, ensuring safe integration and scalable tool usage across commands and agents.

Can I use environment variables for secure authentication with MCP servers?▼

Yes, MCP integration enforces environment-variable substitution and secure authentication patterns when connecting to external services. This ensures safe integration and scalable tool usage across your Claude Code plugins.

Does MCP integration support multi-server orchestration across plugins and agents?▼

Yes, MCP integration supports multi-server orchestration and safe tool usage across plugins, commands, and agents. This enables you to manage multiple external service connections simultaneously within your Claude Code workflows.

What are the limitations when using MCP servers with Claude Code?▼

MCP integration requires proper environment-variable configuration and secure authentication patterns to function correctly. Without these prerequisites, tool discovery via the /mcp command may fail, preventing safe integration of external services.
