What is MCP in the context of Claude Code?

MCP (Model Context Protocol) is an open standard that allows AI models like Claude to connect to external data sources and tools through a unified, secure interface.

Can I bundle multiple MCP servers within a single plugin?

Yes, you can configure multiple servers using either a dedicated .mcp.json file at the plugin root or inline within your plugin.json file.

How are MCP tools referenced in Claude Code commands?

Tools are automatically prefixed using the format 'mcp__plugin_[name]_[server]__[tool]'. You must pre-allow these tools in your command's frontmatter for security.

How does this skill handle authentication for external services?

The skill supports automated OAuth flows for SSE and HTTP-based servers, as well as token-based authentication via environment variable expansion in configuration files.

What is the difference between stdio and SSE server types?

stdio is used for local processes executed as child processes on your machine, while SSE (Server-Sent Events) is designed for connecting to hosted cloud services.

API Development

Integrates Model Context Protocol (MCP) servers into Claude Code plugins to extend AI capabilities with external tools and services.

About

MCP Integration empowers developers to connect Claude Code with external databases, APIs, and cloud services by providing a standardized bridge for tool access. It supports multiple transport protocols including stdio, SSE, HTTP, and WebSockets, enabling seamless authentication via OAuth or environment variables. This skill is essential for building sophisticated AI agents that require real-time data access, complex service integrations, or multi-step autonomous workflows beyond the local file system, ensuring clean architecture through structured tool prefixing and lifecycle management.

Key Features

Structured tool prefixing for organized plugin namespaces
Automated OAuth and token-based authentication management
275 GitHub stars
Dynamic environment variable expansion for secure configuration
Support for stdio, SSE, HTTP, and WebSocket transport protocols
On-demand server lifecycle management and tool discovery

Use Cases

Connecting Claude Code to external SQL or NoSQL databases for real-time data querying
Building autonomous AI agents that interact with custom internal REST APIs or legacy systems
Integrating cloud services like GitHub, Asana, or Jira via official hosted MCP servers
