VS Code、Eclipse添加MCP实现AI代码建议、优化

一、VS Code 插件模板

下面是一个完整的 VS Code 插件模板项目,它可以与 MCP(Model Context Protocol) 交互,并利用 Claude 提供智能代码建议。

该插件的核心功能包括:

  1. 获取当前 MCP 上下文(任务、历史、记忆等)

  2. 调用 Claude 生成代码建议

  3. 在 VS Code 编辑器中插入 AI 生成的代码

  4. 在 VS Code 侧边栏显示任务栈 

1、如何使用

1.安装依赖

npm install -g yo generator-code  # VS Code 扩展生成器
yo code                           # 选择 "New TypeScript Extension"
cd your-extension-name
npm install axios @anthropic-ai/sdk

2.复制以下代码文件

  • src/extension.ts(插件主逻辑)

  • src/panel.ts(侧边栏任务显示)

3.运行插件

npm run watch
code --extensionDevelopmentPath=.

2、src/extension.ts(插件主逻辑)

import * as vscode from 'vscode';
import axios from 'axios';
import Anthropic from '@anthropic-ai/sdk';

// Claude API Key(替换为你的)
const CLAUDE_API_KEY = "你的API密钥";

// MCP 服务器地址
const MCP_API_URL = "http://localhost:8000";

export function activate(context: vscode.ExtensionContext) {
    console.log('🎉 MCP AI 插件已激活!');

    // 注册 "MCP 获取上下文" 命令
    let disposable = vscode.commands.registerCommand('mcp.getContext', async () => {
        try {
            // 从 MCP 获取上下文
            const response = await axios.get(`${MCP_API_URL}/context`);
            const contextData = response.data;
            const task = contextData.task_stack?.[0] || "未找到当前任务";
            const history = contextData.history?.join('\n') || "无历史记录";

            // 构建 Claude Prompt
            const prompt = `
你是一个智能开发助手。当前任务:${task}
历史记录:
${history}

请提供实现该任务的代码建议:
            `;

            // 调用 Claude 生成代码
            const anthropic = new Anthropic({ apiKey: CLAUDE_API_KEY });
            const responseAI = await anthropic.messages.create({
                model: "claude-3-sonnet-20240229",
                max_tokens: 1024,
                messages: [{ role: "user", content: prompt }]
            });

            const aiCode = responseAI.content[0].text || "⚠️ Claude 未返回代码建议";

            // 插入代码到编辑器
            const editor = vscode.window.activeTextEditor;
            if (editor) {
                editor.edit(editBuilder => {
                    editBuilder.insert(editor.selection.active, aiCode);
                });
            }

            vscode.window.showInformationMessage("✅ Claude 代码建议已插入编辑器!");
        } catch (error) {
            console.error("❌ MCP 请求失败:", error);
            vscode.window.showErrorMessage("❌ 获取 MCP 上下文失败,请检查服务器");
        }
    });

    // 注册侧边栏
    context.subscriptions.push(disposable);
    context.subscriptions.push(vscode.window.registerWebviewViewProvider('mcpSidebar', new MCPSidebarProvider(context.extensionUri)));
}

export function deactivate() {
    console.log('🛑 MCP AI 插件已停用');
}

3、src/panel.ts(侧边栏任务栈显示)

import * as vscode from 'vscode';
import axios from 'axios';

const MCP_API_URL = "http://localhost:8000";

export class MCPSidebarProvider implements vscode.WebviewViewProvider {
    private _view?: vscode.WebviewView;

    constructor(private readonly _extensionUri: vscode.Uri) {}

    async resolveWebviewView(webviewView: vscode.WebviewView) {
        this._view = webviewView;
        webviewView.webview.options = { enableScripts: true };

        // 加载任务数据
        this.updateSidebar();
    }

    private async updateSidebar() {
        if (!this._view) return;

        try {
            const response = await axios.get(`${MCP_API_URL}/context`);
            const taskStack = response.data.task_stack || [];
            this._view.webview.html = this.getHTML(taskStack);
        } catch (error) {
            this._view.webview.html = `<h3>❌ 无法连接 MCP</h3>`;
        }
    }

    private getHTML(tasks: string[]): string {
        return `
            <html><body>
            <h3>📌 当前任务栈</h3>
            <ul>${tasks.map(task => `<li>${task}</li>`).join('')}</ul>
            <button onclick="vscode.postMessage({ command: 'refresh' })">🔄 刷新</button>
            <script>
                const vscode = acquireVsCodeApi();
                window.addEventListener('message', event => {
                    location.reload();
                });
            </script>
            </body></html>
        `;
    }
}

4、package.json(扩展定义)

{
    "name": "mcp-ai-helper",
    "displayName": "MCP AI Helper",
    "description": "基于 MCP 和 Claude 的 VS Code 智能助手",
    "version": "1.0.0",
    "engines": { "vscode": "^1.78.0" },
    "categories": ["Other"],
    "activationEvents": ["onCommand:mcp.getContext"],
    "main": "./dist/extension.js",
    "contributes": {
        "commands": [
            {
                "command": "mcp.getContext",
                "title": "获取 MCP 上下文并调用 Claude"
            }
        ],
        "viewsContainers": {
            "activitybar": [
                {
                    "id": "mcp-sidebar",
                    "title": "MCP 任务",
                    "icon": "resources/mcp-icon.png"
                }
            ]
        },
        "views": {
            "mcp-sidebar": [
                {
                    "type": "webview",
                    "id": "mcpSidebar",
                    "name": "MCP 任务栈"
                }
            ]
        }
    },
    "dependencies": {
        "axios": "^0.27.2",
        "@anthropic-ai/sdk": "^0.3.0"
    }
}

5、如何测试插件

1.在 VS Code 里打开插件目录

code .

 2.运行插件

npm run watch
code --extensionDevelopmentPath=.

3.使用 MCP + Claude

  • Ctrl+Shift+P(打开命令面板)

  • 运行 MCP 获取上下文并调用 Claude

  • 侧边栏显示当前任务栈

二、Eclipse 中添加 MCP

要在 Eclipse 中添加 MCP(Model Context Protocol),你可以使用 Eclipse 插件开发(Eclipse Plugin Development Environment, PDE) 来构建一个插件,或者直接在 Eclipse IDE 中编写 Java 代码来集成 MCP。

方法 1:使用 Eclipse 插件(推荐)

这个方法适用于 想要创建 Eclipse 插件来与 MCP 交互 的用户。

步骤 1:创建一个新的 Eclipse 插件项目

  1. 打开 Eclipse,点击 File > New > Plug-in Project

  2. 输入插件名称(例如 MCP Eclipse Plugin),点击 Next

  3. 选择 This plug-in will make contributions to the UI(该插件将为 UI 提供扩展)。

  4. 点击 Finish 创建插件。 

步骤 2:添加 HTTP 依赖

MCP 服务器使用 REST API,我们需要添加 HTTP 请求库 来访问 MCP。

  1. MANIFEST.MF 文件中添加以下依赖:

    • org.eclipse.ui

    • org.eclipse.jface

    • org.apache.httpcomponents.httpclient

    • org.json(用于解析 MCP 返回的 JSON)

  2. 手动导入 Apache HttpClient 依赖(如果 Eclipse 没有内置)

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.13</version>
</dependency>

步骤 3:创建 MCP 连接类

src/com/mcp/eclipse 目录下创建 MCPClient.java

package com.mcp.eclipse;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;

public class MCPClient {
    private static final String MCP_SERVER = "http://localhost:8000";

    public static String getContext() {
        try {
            URL url = new URL(MCP_SERVER + "/context");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuilder response = new StringBuilder();
            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            // 解析 JSON
            JSONObject jsonResponse = new JSONObject(response.toString());
            return jsonResponse.toString(4);  // 格式化输出 JSON
        } catch (Exception e) {
            return "❌ MCP 连接失败: " + e.getMessage();
        }
    }
}

步骤 4:创建 UI 命令

plugin.xml 里添加命令:

<extension
    point="org.eclipse.ui.commands">
    <command
        id="com.mcp.eclipse.getContext"
        name="获取 MCP 上下文">
    </command>
</extension>

 创建 Handler 处理命令,在 src/com/mcp/eclipse 目录下创建 MCPHandler.java

package com.mcp.eclipse;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.ui.PlatformUI;

public class MCPHandler extends AbstractHandler {
    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {
        Shell shell = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell();
        String context = MCPClient.getContext();
        MessageDialog.openInformation(shell, "MCP 上下文", context);
        return null;
    }
}

步骤 5:运行插件

  1. 右键点击项目,选择 Run As > Eclipse Application,启动 Eclipse 插件开发环境。

  2. Window > Preferences 里搜索 MCP,应该可以看到新命令 "获取 MCP 上下文"

  3. 点击 "获取 MCP 上下文",弹出对话框显示 MCP 服务器的当前上下文!🎉

方法 2:在 Java 代码中直接调用 MCP

如果你不想写 Eclipse 插件,而是直接在 Eclipse 里用 Java 代码访问 MCP,可以使用 HttpClient 访问 MCP REST API。

示例:获取 MCP 任务栈

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;

public class MCPClient {
    private static final String MCP_SERVER = "http://localhost:8000";

    public static void main(String[] args) {
        try {
            URL url = new URL(MCP_SERVER + "/context");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuilder response = new StringBuilder();
            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            JSONObject jsonResponse = new JSONObject(response.toString());
            System.out.println("📌 MCP 任务栈: " + jsonResponse.getJSONArray("task_stack"));
        } catch (Exception e) {
            System.out.println("❌ MCP 连接失败: " + e.getMessage());
        }
    }
}

运行后,你会看到类似的输出:

📌 MCP 任务栈: ["修复用户认证漏洞", "优化数据库查询"]

总结

方法适用场景复杂度UI 交互适用开发者
方法 1:Eclipse 插件需要 Eclipse UI 交互(如按钮、对话框)⭐⭐⭐⭐Eclipse 插件开发者
方法 2:Java 直接访问只需获取 MCP 数据,无 UI 需求⭐⭐普通 Java 开发者

三、Eclipse + Claude + MCP 代码建议

这个 Eclipse 插件 可以:

  1. 获取 MCP 任务栈(从 /context 读取任务信息)

  2. 调用 Claude 生成代码建议(基于当前任务)

  3. 在 Eclipse 编辑器中插入 AI 代码

  4. 在侧边栏显示任务栈(实时更新) 

步骤 1:创建 Eclipse 插件

  1. 打开 EclipseFile > New > Plug-in Project

  2. 输入项目名称(如 MCP_AI_Helper),点击 Next

  3. 选择 UI 插件This plug-in will make contributions to the UI

  4. 点击 Finish 创建插件 

步骤 2:添加依赖

  • 打开 MANIFEST.MF,在 Dependencies 里添加:

    • org.eclipse.ui

    • org.eclipse.jface

    • org.apache.httpcomponents.httpclient

    • org.json

  • 手动添加 Claude SDK

    • 下载 Anthropic Claude API

    • 复制 anthropic-sdk.jarlib/ 目录

    • MANIFEST.MF 里添加 anthropic-sdk 依赖 

步骤 3:创建 MCP 连接类

src/com/mcp/eclipse/MCPClient.java

package com.mcp.eclipse;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import org.json.JSONObject;

public class MCPClient {
    private static final String MCP_SERVER = "http://localhost:8000";

    public static String getContext() {
        try {
            URL url = new URL(MCP_SERVER + "/context");
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestMethod("GET");

            BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuilder response = new StringBuilder();
            String inputLine;
            while ((inputLine = in.readLine()) != null) {
                response.append(inputLine);
            }
            in.close();

            JSONObject jsonResponse = new JSONObject(response.toString());
            return jsonResponse.getJSONArray("task_stack").getString(0);  // 取最新任务
        } catch (Exception e) {
            return "❌ MCP 连接失败: " + e.getMessage();
        }
    }
}

步骤 4:创建 Claude 代码建议

src/com/mcp/eclipse/ClaudeClient.java

package com.mcp.eclipse;

import anthropic.sdk.*;
import anthropic.sdk.resources.*;

public class ClaudeClient {
    private static final String CLAUDE_API_KEY = "你的API密钥";

    public static String generateCode(String task) {
        try {
            Anthropic anthropic = new Anthropic.Builder().apiKey(CLAUDE_API_KEY).build();
            MessageResponse response = anthropic.messages()
                    .create(new MessageRequest.Builder()
                            .model("claude-3-sonnet-20240229")
                            .maxTokens(1024)
                            .message(new Message.Builder()
                                    .role("user")
                                    .content("请为以下任务提供代码建议:\n" + task)
                                    .build())
                            .build());
            
            return response.content().get(0).text();
        } catch (Exception e) {
            return "❌ Claude 请求失败: " + e.getMessage();
        }
    }
}

步骤 5:创建 UI 命令

plugin.xml 添加:

<extension
    point="org.eclipse.ui.commands">
    <command
        id="com.mcp.eclipse.getCode"
        name="获取 Claude 代码建议">
    </command>
</extension>

步骤 6:创建命令 Handler

src/com/mcp/eclipse/CodeSuggestionHandler.java

package com.mcp.eclipse;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.text.IDocument;
import org.eclipse.jface.text.ITextSelection;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.texteditor.ITextEditor;
import org.eclipse.jface.dialogs.MessageDialog;

public class CodeSuggestionHandler extends AbstractHandler {
    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {
        IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        IEditorPart editor = window.getActivePage().getActiveEditor();

        if (editor instanceof ITextEditor) {
            ITextEditor textEditor = (ITextEditor) editor;
            IDocument document = textEditor.getDocumentProvider().getDocument(textEditor.getEditorInput());
            ITextSelection selection = (ITextSelection) textEditor.getSelectionProvider().getSelection();
            
            // 获取 MCP 任务
            String task = MCPClient.getContext();
            if (task.startsWith("❌")) {
                MessageDialog.openError(window.getShell(), "MCP 错误", task);
                return null;
            }

            // 调用 Claude 生成代码
            String code = ClaudeClient.generateCode(task);
            if (code.startsWith("❌")) {
                MessageDialog.openError(window.getShell(), "Claude 错误", code);
                return null;
            }

            // 插入到 Eclipse 编辑器
            int offset = selection.getOffset();
            try {
                document.replace(offset, 0, "\n" + code + "\n");
                MessageDialog.openInformation(window.getShell(), "Claude 代码建议", "代码已插入编辑器!");
            } catch (Exception e) {
                MessageDialog.openError(window.getShell(), "插入失败", e.getMessage());
            }
        }
        return null;
    }
}

步骤 7:添加侧边栏

plugin.xml 添加:

<extension
    point="org.eclipse.ui.views">
    <view
        id="com.mcp.eclipse.taskView"
        name="MCP 任务栈"
        class="com.mcp.eclipse.TaskView"
        category="org.eclipse.ui">
    </view>
</extension>

 创建 src/com/mcp/eclipse/TaskView.java

package com.mcp.eclipse;

import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.List;
import org.eclipse.ui.part.ViewPart;
import org.json.JSONObject;

public class TaskView extends ViewPart {
    private List taskList;

    @Override
    public void createPartControl(Composite parent) {
        taskList = new List(parent, SWT.BORDER | SWT.V_SCROLL);
        updateTasks();
    }

    private void updateTasks() {
        String jsonResponse = MCPClient.getContext();
        try {
            JSONObject json = new JSONObject(jsonResponse);
            taskList.removeAll();
            for (Object task : json.getJSONArray("task_stack")) {
                taskList.add(task.toString());
            }
        } catch (Exception e) {
            taskList.add("❌ MCP 连接失败");
        }
    }

    @Override
    public void setFocus() {
        updateTasks();
    }
}

步骤 8:运行插件

  1. 在 Eclipse 中打开 Run > Run Configurations

  2. 选择 Eclipse Application,然后点击 Run

  3. Eclipse 界面

    • Window > Show View > Other...

    • 搜索 MCP 任务栈,点击打开

  4. 使用 Claude 代码建议

    • 选中代码编辑器

    • Ctrl+3 搜索 获取 Claude 代码建议

    • 插入 AI 代码 🎉

四、Eclipse 让 Claude 进行代码优化

要让 Claude 进行代码优化,我们可以在 Eclipse 插件 里添加一个新功能,允许 Claude 分析当前代码并自动优化

功能设计

  1. 获取 Eclipse 编辑器的代码

  2. 调用 Claude API,要求优化代码

  3. 将优化后的代码插入 Eclipse 编辑器

  4. 弹出对话框显示优化结果 

步骤 1:创建命令

plugin.xml 添加:

<extension
    point="org.eclipse.ui.commands">
    <command
        id="com.mcp.eclipse.optimizeCode"
        name="优化代码(Claude)">
    </command>
</extension>

步骤 2:创建 OptimizeCodeHandler.java

src/com/mcp/eclipse/OptimizeCodeHandler.java

package com.mcp.eclipse;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.text.IDocument;
import org.eclipse.jface.text.ITextSelection;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.texteditor.ITextEditor;
import org.eclipse.jface.dialogs.MessageDialog;

public class OptimizeCodeHandler extends AbstractHandler {
    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {
        IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        IEditorPart editor = window.getActivePage().getActiveEditor();

        if (editor instanceof ITextEditor) {
            ITextEditor textEditor = (ITextEditor) editor;
            IDocument document = textEditor.getDocumentProvider().getDocument(textEditor.getEditorInput());
            ITextSelection selection = (ITextSelection) textEditor.getSelectionProvider().getSelection();
            
            // 获取选中的代码
            String code = selection.getText();
            if (code.trim().isEmpty()) {
                MessageDialog.openError(window.getShell(), "错误", "请先选中需要优化的代码!");

public class ClaudeClient {
    private static final String CLAUDE_API_KEY = "你的API密钥";

    public static String optimizeCode(String code) {
        try {
            Anthropic anthropic = new Anthropic.Builder().apiKey(CLAUDE_API_KEY).build();
            MessageResponse response = anthropic.messages()
                    .create(new MessageRequest.Builder()
                            .model("claude-3-opus-20240229")  // 选用更强的优化模型
                            .maxTokens(2048)
                            .message(new Message.Builder()

<extension
    point="org.eclipse.ui.commands">
    <command
        id="com.mcp.eclipse.autoOptimize"
        name="自动优化代码(Claude)">
    </command>
</extension>

步骤 2:创建 AutoOptimizeHandler.java

            // 获取代码
            String code = selection.getText();
            if (code.trim().isEmpty()) {
                MessageDialog.openError(window.getShell(), "错误", "请先选中需要优化的代码!");
                return null;
            }

            // 选择优化模式
            String mode = selectOptimizationMode(window.getShell());
            if (mode == null) {
                return null;
            }

            // 让 Claude 进行优化
            String optimizedCode = ClaudeClient.autoOptimizeCode(code, mode);
            if (optimizedCode.startsWith("❌")) {
                MessageDialog.openError(window.getShell(), "Claude 错误", optimizedCode);
                return null;
            }

            // 插入优化后的代码
            int offset = selection.getOffset();
            try {
                document.replace(offset, selection.getLength(), optimizedCode);
                MessageDialog.openInformation(window.getShell(), "Claude 自动优化", "代码已优化!");
            } catch (Exception e) {
                MessageDialog.openError(window.getShell(), "插入失败", e.getMessage());
            }
        }
        return null;
    }

    private String selectOptimizationMode(Shell shell) {
        MessageBox dialog = new MessageBox(shell, SWT.ICON_QUESTION | SWT.YES | SWT.NO | SWT.CANCEL);
        dialog.setText("选择优化模式");
        dialog.setMessage("请选择优化方式:\n\n是(YES)= 性能优化\n否(NO)= 可读性优化\n取消 = 结构优化");

        int response = dialog.open();
        if (response == SWT.YES) {
            return "performance";
        } else if (response == SWT.NO) {

        } else {
            return "structure";
        }
    }
}

Claude 代码优化、注释、格式化
优化前后代码对比

步骤 1:更新 MCPClient.java

通过 API 连接 MCP

package com.mcp.eclipse;

import java.io.OutputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.Scanner;
import javax.net.ssl.HttpsURLConnection;

public class MCPClient {
    private static final String MCP_API_URL = "https://your-mcp-server.com/api"; // 修改为你的MCP服务器地址
    private static final String API_KEY = "your-mcp-api-key"; // 替换为你的 API 密钥

    // 发送请求到 MCP API
    public static String sendRequest(String payload) {
        try {
            URL url = new URL(MCP_API_URL);
            HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setRequestProperty("Content-Type", "application/json");
            connection.setRequestProperty("Authorization", "Bearer " + API_KEY);
            connection.setDoOutput(true);

            // 发送 JSON 请求
            try (OutputStream os = connection.getOutputStream()) {
                byte[] input = payload.getBytes("utf-8");
                os.write(input, 0, input.length);
            }

            // 读取响应
            int status = connection.getResponseCode();
            if (status == 200) {
                try (Scanner scanner = new Scanner(connection.getInputStream(), "utf-8")) {
                    return scanner.useDelimiter("\\A").next();
                }
            } else {
                return "❌ MCP 请求失败: " + status;
            }
        } catch (Exception e) {
            return "❌ MCP API 连接错误: " + e.getMessage();
        }
    }

    // 代码优化请求
    public static String optimizeCode(String code) {
        String payload = "{ \"task\": \"optimize\", \"code\": " + "\"" + code.replace("\"", "\\\"") + "\" }";
        return sendRequest(payload);
    }

    // 代码格式化请求
    public static String formatCode(String code) {
        String payload = "{ \"task\": \"format\", \"code\": " + "\"" + code.replace("\"", "\\\"") + "\" }";
        return sendRequest(payload);
    }

    // 代码注释请求
    public static String commentCode(String code) {
        String payload = "{ \"task\": \"comment\", \"code\": " + "\"" + code.replace("\"", "\\\"") + "\" }";
        return sendRequest(payload);
    }
}

步骤 2:更新 AutoOptimizeHandler.java

集成 MCP API 代码优化

package com.mcp.eclipse;

import org.eclipse.core.commands.AbstractHandler;
import org.eclipse.core.commands.ExecutionEvent;
import org.eclipse.core.commands.ExecutionException;
import org.eclipse.jface.text.IDocument;
import org.eclipse.jface.text.ITextSelection;
import org.eclipse.ui.IEditorPart;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.PlatformUI;
import org.eclipse.ui.texteditor.ITextEditor;
import org.eclipse.jface.dialogs.MessageDialog;
import org.eclipse.jface.window.Window;
import org.eclipse.swt.widgets.Shell;

public class AutoOptimizeHandler extends AbstractHandler {
    @Override
    public Object execute(ExecutionEvent event) throws ExecutionException {
        IWorkbenchWindow window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();
        IEditorPart editor = window.getActivePage().getActiveEditor();

        if (editor instanceof ITextEditor) {
            ITextEditor textEditor = (ITextEditor) editor;
            IDocument document = textEditor.getDocumentProvider().getDocument(textEditor.getEditorInput());
            ITextSelection selection = (ITextSelection) textEditor.getSelectionProvider().getSelection();
            
            String originalCode = selection.getText();
            if (originalCode.trim().isEmpty()) {
                MessageDialog.openError(window.getShell(), "错误", "请先选中需要优化的代码!");
                return null;
            }

            // 调用 MCP 进行代码优化
            String optimizedCode = MCPClient.optimizeCode(originalCode);
            if (optimizedCode.startsWith("❌")) {
                MessageDialog.openError(window.getShell(), "MCP 错误", optimizedCode);
                return null;
            }

            // 代码优化前后对比
            Shell shell = window.getShell();
            CodeDiffDialog diffDialog = new CodeDiffDialog(shell, originalCode, optimizedCode);
            if (diffDialog.open() == Window.OK) {
                int offset = selection.getOffset();
                try {
                    document.replace(offset, selection.getLength(), optimizedCode);
                    MessageDialog.openInformation(shell, "MCP 代码优化", "代码已优化!");
                } catch (Exception e) {
                    MessageDialog.openError(shell, "插入失败", e.getMessage());
                }
            }
        }
        return null;
    }
}

步骤 3:更新 plugin.xml

<think>好的,我需要帮助用户了解如何使用vite-plugin-vue-mcp插件。首先,用户提到了几个引用,其中引用[2]和[4]相关。引用[2]说明该插件是为Vue应用设计的,通过启用MCP服务器帮助模型理解应用。引用[4]提供了创建Vite项目的命令。 首先,我应该检查是否有官方文档或社区资源,但用户提供的引用中没有详细教程。可能需要根据现有信息整理步骤。步骤应包括创建Vue项目、安装插件、配置vite.config.js、启动项目等。同时,要提到MCP服务器的功能,如组件解析、API模拟等,如引用[2]所述。 用户可能遇到的问题,比如插件兼容性或配置错误,需要提醒注意Vite和Vue版本。此外,生成相关问题时,可以涉及插件功能、与其他工具集成、调试方法等。确保回答结构清晰,步骤详细,并引用相关来源。</think>### vite-plugin-vue-mcp 使用指南 #### 1. 环境准备 首先确保已创建基于Vue的Vite项目,若未创建可执行以下命令: ```bash npm init vite@latest my-vue-project -- --template vue ``` 该命令会生成符合Vue 3项目结构的模板[^4]。 #### 2. 插件安装 在项目根目录执行安装命令: ```bash npm install vite-plugin-vue-mcp --save-dev ``` 或使用yarn: ```bash yarn add vite-plugin-vue-mcp -D ``` #### 3. 配置插件 在`vite.config.js`中添加配置: ```javascript import { defineConfig } from 'vite' import vue from '@vitejs/plugin-vue' import mcp from 'vite-plugin-vue-mcp' export default defineConfig({ plugins: [ vue(), mcp({ mcpServer: { port: 3001, // MCP服务器端口 mockMode: true // 启用API模拟 } }) ] }) ``` 通过该配置可启用MCP服务器的组件智能解析功能[^2]。 #### 4. 启动开发环境 ```bash npm run dev ``` 此时插件会自动: - 生成组件依赖图谱 - 启动API模拟服务器 - 注入运行时调试工具 #### 5. 核心功能使用 | 功能 | 使用场景 | 配置示例 | |----------------|-----------------------------|--------------------------| | 组件智能分析 | 可视化组件层级关系 | `analysisDepth: 3` | | 模型训练 | 提升AI代码的理解能力 | `trainInterval: 3600` | | API模拟 | 前端独立开发环境搭建 | `mockPaths: ['/api']` | #### 注意事项 1. 需要Node.js 16+环境 2. Vue 3.2+版本推荐使用 3. 若遇到HMR不生效,尝试添加`hotUpdate: true`配置
