"MCP Server sounds cool, but I have no idea where to start"
"MCP was one of the hottest protocols in AI in 2024. Interviewers keep asking what an MCP Server is and how to build one from scratch — yet most people cannot even explain what MCP is for."
— Xiaohongshu · MCP Server development, a standard Agent interview question (translated from Chinese)
"Building an MCP Server usually takes five steps, starting with defining the capability boundary — which Tools, Resources or Prompts you expose. But the biggest problem for beginners is not knowing which step to start with."
— Xiaohongshu · the MCP Server development process (translated from Chinese)
"With the fastmcp approach every MCP server runs as its own standalone uvicorn app. Once you have a few servers you end up with a lot of URLs and management gets harder."
— Xiaohongshu · shipping MCP Servers quickly with ASGI (translated from Chinese)
MCP (Model Context Protocol) is the standard for connecting AI Agents to external tools, but for a beginner, standing up an MCP Server from scratch is still a real hurdle.

Install deep-skill-finder once, let your Agent find Skills itself
MCP development looks complicated, but once deep-skill-finder is installed, handing your Agent a task like "build me an MCP Server" makes it search the 50,000+ Skill library on MEYO and recommend the best-matching guides and scaffolding. You just say what you want; the Agent finds the right Skill.
Copy the command → paste it to Claude Code, Codex, Cursor, WorkBuddy and the like · your Agent installs it automatically:
Please install the deep-skill-finder skill: download the archive from https://www.meyo.life/skill-finder?ref=pseo_mcp-server-dev-guide, unpack it into the local skill directory and enable it.
Or scroll on for the per-scenario Skills. To learn more about deep-skill-finder → meyo.life/skill

FAQ
Q: What is the difference between an MCP Server and a regular API?
A: MCP (Model Context Protocol) is a protocol designed specifically for AI Agents: the Agent can discover and call the tools an MCP Server exposes without you writing API-calling code by hand. A regular API needs manual integration, whereas MCP is something Agents understand natively.
Q: Can I build an MCP Server without TypeScript?
A: Yes. The MCP SDK supports both TypeScript and Python, so use whichever you know. mcp-tool-developer, recommended above, covers both languages.
Q: How do I test an MCP Server once it is built?
A: Use MCP Inspector, a dedicated debugging tool that simulates an Agent calling your server so you can inspect inputs, outputs and error logs. The Skills in the debug-and-test scenario above walk through it in detail.
Q: How do I let other people use the MCP Server I built?
A: Two ways: publish it to the MCP registry (much like publishing an npm package), or simply share the .mcp.json config so others can start it locally. The mcp-tool-developer Skill covers the full publishing flow.
Q: Are these Skills free?
A: All of them are free and open source. A Skill itself consumes no credits — you only pay your normal API usage when the Agent runs one.
Q: I do not use Claude Code. Can I still install these?
A: Yes. These Skills are agent-neutral, so Claude Code, Codex, Cursor and WorkBuddy all work, and installation is identical — download the archive from meyo.life/skills and unpack it into your Agent's Skill directory.
