README
Dev Tools MCP Server
这是一个使用TypeScript编写的MCP(Model Context Protocol)服务器示例。
功能
这个MCP服务器提供了以下工具:
-
hello_world - 简单的问候工具
- 参数:
name(string) - 要问候的人名
- 参数:
-
calculate - 简单的计算器
- 参数:
operation(string) - 运算类型:add, subtract, multiply, dividea(number) - 第一个数字b(number) - 第二个数字
- 参数:
-
file_info - 获取文件信息
- 参数:
path(string) - 文件路径
- 参数:
安装和运行
1. 安装依赖
npm install
2. 构建项目
npm run build
3. 运行服务器
npm start
开发模式运行
npm run dev
测试
项目包含一个测试文件 test-mcp.js,用于验证MCP服务器的功能:
node test-mcp.js
测试会验证:
- 服务器初始化
- 工具列表获取
- hello_world 工具调用
- calculate 工具的各种运算
- file_info 工具的文件信息获取
与AI模型集成
要将此MCP服务器与支持MCP的AI模型集成,你需要在AI模型的配置文件中添加此服务器。
示例配置(Claude Desktop)
在Claude Desktop的配置文件中添加:
{
"mcpServers": {
"dev-tools": {
"command": "node",
"args": ["/path/to/your/dev-tools/dist/server.js"],
"env": {}
}
}
}
示例配置(Cursor)
在Cursor的MCP配置中添加:
{
"mcpServers": {
"dev-tools": {
"command": "node",
"args": ["/path/to/your/dev-tools/dist/server.js"]
}
}
}

添加新工具
- 在
src/server.ts中定义新的参数模式:
const NewToolArgsSchema = z.object({
// 定义参数
});
- 在
tools数组中添加新工具:
{
name: "new_tool",
description: "工具描述",
inputSchema: NewToolArgsSchema,
}
- 在
CallToolRequest处理函数中添加新的case:
case "new_tool": {
const args = NewToolArgsSchema.parse(request.params.arguments);
// 实现工具逻辑
return {
content: [
{
type: "text",
text: "结果",
},
],
};
}
- 在
test-mcp.js中添加测试用例:
{
jsonrpc: "2.0",
id: 7,
method: "tools/call",
params: {
name: "new_tool",
arguments: {
// 测试参数
}
}
}
