The instructions your AI receives, as published by chris-debug-0225/learn-claude-code-java in skills/mcp-builder/SKILL.md and read by ahel’s review.

You now have expertise in building MCP (Model Context Protocol) servers. MCP enables Claude to interact with external services through a standardized protocol.

What is MCP?

MCP servers expose:

  • Tools: Functions Claude can call
  • Resources: Data Claude can read
  • Prompts: Pre-built prompt templates

Quick Start: Python MCP Server

from mcp.server import Server
from mcp.server.stdio import stdio_server

server = Server("my-server")

@server.tool()
async def hello(name: str) -> str:
    return f"Hello, {name}!"

TypeScript MCP Server

import { Server } from "@modelcontextprotocol/sdk/server/index.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

const server = new Server({ name: "my-server", version: "1.0.0" });
const transport = new StdioServerTransport();
server.connect(transport);

Best Practices

  1. Clear tool descriptions
  2. Input validation
  3. Meaningful error handling
  4. Async for I/O
  5. Security first
  6. Idempotent tools when possible
