How do I access MCP tools within a Claude command?

Tools must be pre-allowed in the command frontmatter using the specific prefix format: mcp__plugin_[plugin]_[server]__[tool_name].

Can I use multiple MCP servers in a single plugin?

Yes, you can configure multiple servers within a single .mcp.json file to provide a diverse suite of tools across different services.

What is the Model Context Protocol (MCP)?

MCP is an open standard that allows AI models like Claude to securely connect to external tools, data sources, and services using a standardized interface.

How do I secure API keys in an MCP configuration?

Always use environment variable expansion (e.g., ${MY_API_KEY}) in your .mcp.json or plugin.json files instead of hardcoding sensitive credentials.

What is the difference between stdio and SSE servers?

Stdio servers run as local child processes for system-level tasks, while SSE (Server-Sent Events) servers connect to remote cloud services and often support OAuth.

API Development

Integrates Model Context Protocol (MCP) servers into Claude Code plugins to enable secure connectivity with external tools, databases, and APIs.

This skill provides comprehensive architectural guidance and implementation patterns for extending Claude Code using the Model Context Protocol. It offers detailed instructions for configuring various transport types—including local stdio processes, hosted SSE, REST-based HTTP, and real-time WebSockets—ensuring developers can build powerful plugins that interact with external services. With deep dives into OAuth authentication, environment variable expansion, and automated tool registration, this skill helps developers transform Claude into a fully-equipped autonomous agent capable of complex service orchestration.
