什么是MCP Server?

Model Context Protocol(MCP)是一种开放协议,它让AI助手能够与外部工具和数据源无缝集成。简单来说,MCP Server就是让Claude Code调用您自定义工具的桥梁。通过MCP,您可以:

项目准备与环境配置

在开始开发之前,请确保已安装以下工具:

# Node.js环境要求
node --version  # 需要 v18.0.0 或更高版本
npm --version   # 需要 v9.0.0 或更高版本

全局安装MCP CLI工具

npm install -g @anthropic-ai/mcp-cli

验证安装

mcp --version

创建您的第一个MCP Server

作为有多年集成经验的开发者,我强烈建议从简单的工具开始,逐步扩展复杂度。下面我将展示如何使用Python和TypeScript分别创建MCP Server,并集成到Claude Code中。

方式一:Python MCP Server实现

# 安装必要的依赖
pip install mcp fastapi uvicorn httpx

创建 mcp_server.py

from mcp.server.fastapi import FastAPIMCP from fastapi import FastAPI import httpx import os

HolySheep API配置 - 请替换为您的密钥

HOLYSHEEP_API_KEY = os.getenv("HOLYSHEEP_API_KEY", "YOUR_HOLYSHEEP_API_KEY") HOLYSHEEP_BASE_URL = "https://api.holysheep.ai/v1" app = FastAPI(title="MCP Server - HolySheep集成") mcp = FastAPIMCP(app) @mcp.tool() async def ask_ai_anything(prompt: str, model: str = "claude-sonnet-4.5-20250514") -> dict: """ 通过HolySheep AI API发送请求到Claude 支持的模型: claude-sonnet-4.5-20250514, gpt-4.1, deepseek-v3.2 """ async with httpx.AsyncClient(timeout=60.0) as client: response = await client.post( f"{HOLYSHEEP_BASE_URL}/chat/completions", headers={ "Authorization": f"Bearer {HOLYSHEEP_API_KEY}", "Content-Type": "application/json" }, json={ "model": model, "messages": [{"role": "user", "content": prompt}], "max_tokens": 2048, "temperature": 0.7 } ) result = response.json() return { "content": result["choices"][0]["message"]["content"], "model_used": model, "usage": result.get("usage", {}), "latency_ms": response.elapsed.total_seconds() * 1000 } @mcp.tool() async def translate_code(code: str, source_lang: str, target_lang: str) -> dict: """代码翻译工具 - 支持多种编程语言互转""" prompt = f"""将以下{source_lang}代码翻译成{target_lang}。 只返回代码,不要解释。 ```{source_lang} {code} ```""" return await ask_ai_anything(prompt, model="deepseek-v3.2") # 使用便宜的DeepSeek模型 @mcp.tool() async def explain_code_snippet(code: str, language: str = "python") -> dict: """代码解释工具 - 详细解释代码逻辑""" prompt = f"""详细解释以下{language}代码的功能、工作原理和潜在改进建议: ```{language} {code} ```""" return await ask_ai_anything(prompt, model="claude-sonnet-4.5-20250514")

运行服务器

if __name__ == "__main__": import uvicorn print("🚀 MCP Server已启动: http://localhost:8000/mcp") print(f"📡 使用HolySheep API: {HOLYSHEEP_BASE_URL}") uvicorn.run(app, host="0.0.0.0", port=8000)

方式二:TypeScript/Node.js MCP Server实现

# 初始化项目
mkdir holy-sheep-mcp && cd holy-sheep-mcp
npm init -y
npm install @modelcontextprotocol/sdk typescript ts-node

创建 src/index.ts

import { Server } from "@modelcontextprotocol/sdk/server/index.js"; import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; import { CallToolRequestSchema, ListToolsRequestSchema, } from "@modelcontextprotocol/sdk/types.js"; import axios from "axios"; // HolySheep API配置 const HOLYSHEEP_API_KEY = process.env.HOLYSHEEP_API_KEY || "YOUR_HOLYSHEEP_API_KEY"; const HOLYSHEEP_BASE_URL = "https://api.holysheep.ai/v1"; // 创建MCP服务器实例 const server = new Server( { name: "holy-sheep-mcp-server", version: "1.0.0", }, { capabilities: { tools: {}, }, } ); // 工具列表定义 server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: [ { name: "analyze_code_quality", description: "分析代码质量并提供改进建议", inputSchema: { type: "object", properties: { code: { type: "string", description: "要分析的代码" }, language: { type: "string", description: "编程语言" } }, required: ["code"] } }, { name: "generate_unit_tests", description: "为代码生成单元测试", inputSchema: { type: "object", properties: { code: { type: "string", description: "需要生成测试的代码" }, framework: { type: "string", description: "测试框架 (jest, pytest, etc.)" } }, required: ["code"] } }, { name: "refactor_code", description: "重构并优化代码", inputSchema: { type: "object", properties: { code: { type: "string", description: "需要重构的代码" }, target_style: { type: "string", description: "目标代码风格" } }, required: ["code"] } } ] }; }); // 工具调用处理器 server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: args } = request.params; try { switch (name) { case "analyze_code_quality": { const response = await axios.post( ${HOLYSHEEP_BASE_URL}/chat/completions, { model: "claude-sonnet-4.5-20250514", messages: [{ role: "user", content: `分析以下${args.language}代码的质量,指出问题并提供改进建议: ${args.code}` }], max_tokens: 1500 }, { headers: { "Authorization": Bearer ${HOLYSHEEP_API_KEY}, "Content-Type": "application/json" } } ); return { content: [{ type: "text", text: response.data.choices[0].message.content }] }; } case "generate_unit_tests": { const response = await axios.post( ${HOLYSHEEP_BASE_URL}/chat/completions, { model: "gpt-4.1", messages: [{ role: "user", content: `为以下代码使用${args.framework}生成单元测试: ${args.code}` }], max_tokens: 2000 }, { headers: { "Authorization": Bearer ${HOLYSHEEP_API_KEY}, "Content-Type": "application/json" } } ); return { content: [{ type: "text", text: response.data.choices[0].message.content }] }; } case "refactor_code": { const response = await axios.post( ${HOLYSHEEP_API_KEY}/chat/completions, { model: "deepseek-v3.2", messages: [{ role: "user", content: `重构以下代码,遵循${args.target_style || "最佳实践"}风格: ${args.code}` }], max_tokens: 2000 }, { headers: { "Authorization": Bearer ${HOLYSHEEP_API_KEY}, "Content-Type": "application/json" } } ); return { content: [{ type: "text", text: response.data.choices[0].message.content }] }; } default: throw new Error(未知工具: ${name}); } } catch (error: any) { return { content: [{ type: "text", text: 错误: ${error.message} }], isError: true }; } }); // 启动服务器 async function main() { const transport = new StdioServerTransport(); await server.connect(transport); console.error("✅ HolySheep MCP Server 已启动并运行中..."); } main().catch(console.error);

配置Claude Code使用MCP Server

创建MCP Server后,需要在Claude Code中注册和启用这些工具。

# 在项目根目录创建 .claude/mcp.json

配置Claude Code使用我们的MCP Server

{ "mcpServers": { "holy-sheep-tools": { "command": "node", "args": ["dist/index.js"], "env": { "HOLYSHEEP_API_KEY": "YOUR_HOLYSHEEP_API_KEY" } } } }

如果使用Python版本

创建 .claude/mcp.json (Python配置)

{ "mcpServers": { "holy-sheep-python": { "command": "python", "args": ["/path/to/mcp_server.py"] } } }

运行Claude Code测试MCP集成

claude

在Claude Code中测试工具

/使用 analyze_code_quality 分析代码质量

/使用 generate_unit_tests 生成单元测试

/使用 refactor_code 重构代码
