I’ve compiled reference information including official documentation, implementation examples, security considerations, and interesting use cases that I encountered while learning about MCP (Model Context Protocol), which has been gaining momentum recently.

XユーザーのVさん: 「皆 UUID 生成する MCP サーバー書いててとても良いぞってなってる。」 / X (“Everyone is writing MCP servers that generate UUIDs and it’s really great.”)

Seeing this post, I actually tried implementing a simple MCP server in TypeScript myself.

This article introduces resources useful for learning MCP, information helpful for implementation, security considerations, and interesting application examples.

What is MCP?

First, to understand what MCP (Model Context Protocol) is, it’s best to refer to the official documentation.

• Official Documentation: Introduction - Model Context Protocol
• GitHub Repository: https://github.com/modelcontextprotocol

Thanks to the following slides, I was able to understand MCP in an easy-to-understand way.

• MCPに入門する/ Introduction to MCP - Speaker Deck

Also, regarding “Why MCP now?” and its background and benefits, the following blog post provides a very clear explanation.

• なぜ MCP なのか (“Why MCP?”)

MCP Implementation - Considerations for TypeScript

When considering actually implementing an MCP server, particularly for production-ready implementations in TypeScript, the following repository was helpful:

• fastmcp: punkpeye/fastmcp (github.com)

MCP and Security

Security is a very important aspect when publishing and operating MCP servers. The following blog post explains specific measures and precautions for safely operating MCP servers.

• MCPサーバーを安全に動かすための工夫 (“Measures for safely operating MCP servers”)

Aside: Unique Application Examples of MCP

The scope of MCP applications is broad and not limited to technical aspects. The following article provides a very interesting perspective on applying MCP concepts to human-based processes.

• 👨‍🔧 人間をMCPツールとして利用する (“Using humans as MCP tools”)

I had been thinking that “using Human-in-the-Loop to its fullest for prototyping products utilizing MCP might be interesting,” so it was intriguing to see someone already practicing this.

Summary

Although MCP is a relatively new technology, various applications are expected across different fields due to its simplicity and extensibility. I hope this can serve as a reference for those who want to explore MCP and learn about the technology.

That’s all from the Gemba.
