代码重构助手

把遗留代码重构为现代规范代码，保持原有接口与行为不变

一个基于本地大模型的代码重构服务。输入一段源代码和一句重构要求，输出重构后的完整代码。

代码不离开你的机器 —— 核心版通过本地 Ollama 推理，无任何数据上传。

快速开始 · 功能 · 使用方式 · 定价 · 贡献

这是什么

历史项目里总有些代码：能跑，但没人愿意碰。变量叫 a、tmp1、data2，三层嵌套的 if 里塞着业务逻辑，同一个校验规则在五个地方各写了一遍。

这个项目做的就是把这些代码改造好。它不修复 bug、不添加功能，只改结构——让代码好读、好改，同时保证外部行为完全不变。

核心能力由本地 Ollama 上的代码模型（默认 deepseek-coder）驱动，可以以 MCP Server、HTTP API、技能包 等多种形态接入你现有的工作流。

功能

支持语言：Python · JavaScript · TypeScript · Java · Go · Rust · C · C++

设计原则

重构这件事，改坏比不改更糟。所以本项目有两条硬约束：

  1. 不改公共接口 —— 函数名、类名、参数签名、返回值结构保持原样（除非你明确要求改）
  2. 保持行为等价 —— 重构后逻辑与原代码一致，不顺手修 bug

快速开始

前置条件

  • Python 3.11+ 或 Node.js 18+
  • Ollama 已安装并运行
  • 已拉取代码模型：ollama pull deepseek-coder

方式一：本地 Python 直接调用

git clone https://github.com/zhouhengchang/code-refactor.git
cd code-refactor
python shared/refactor_core.py   # 内置自测，会先检查服务再跑一个示例

也可以在自己的代码里调用：

# -*- coding: utf-8 -*-
"""最小调用示例。"""

from shared.refactor_core import refactor_code, check_ollama_status

# 先确认环境就绪
print(check_ollama_status())

# 执行重构
result = refactor_code(
    code="def f(a):\n    r = []\n    for i in a:\n        if i % 2 == 0:\n            r.append(i * i)\n    return r\n",
    task="重命名为有意义的函数名与变量名，补充类型标注与中文注释",
    language="python",
)

if result["ok"]:
    print(result["code"])
else:
    print("失败：", result["error"])

方式二：作为 MCP Server 接入（Claude Desktop / WorkBuddy / 任意 MCP 客户端）

已发布到 npm，不用克隆仓库，直接在 MCP 客户端配置里引用：

{
  "mcpServers": {
    "code-refactor": {
      "command": "npx",
      "args": ["-y", "workbuddy-code-refactor-connector"],
      "env": {
        "REFACTOR_BACKEND": "ollama",
        "OLLAMA_HOST": "http://localhost:11434",
        "OLLAMA_MODEL": "deepseek-coder"
      }
    }
  }
}

npm 包：workbuddy-code-refactor-connector

也可以从源码运行，便于自己改代码：

cd workbuddy-connector/server
npm install

然后把上面的 command 改成 node，args 改成 ["/绝对路径/to/workbuddy-connector/server/index.js"] 即可。

重启客户端后即可使用 refactorcode 和 checkstatus 两个工具。

方式三：Docker 部署 HTTP 服务

docker build -t code-refactor-xpack:1.0.0 -f xpack-server/Dockerfile .
docker run -p 8000:8000 \
  -e OLLAMA_HOST=http://host.docker.internal:11434 \
  -e OLLAMA_MODEL=deepseek-coder \
  code-refactor-xpack:1.0.0

调用：

curl -X POST http://localhost:8000/refactor \
  -H "Content-Type: application/json" \
  -d '{
    "code": "def f(a):\n    return [i*i for i in a if i % 2 == 0]\n",
    "task": "函数名与变量名改为有意义的命名，补充类型标注",
    "language": "python"
  }'

使用方式

输入

输出

{
  "ok": true,
  "code": "重构后的完整代码",
  "model": "deepseek-coder",
  "language": "python",
  "elapsed_ms": 3820
}

Code Refactor: common questions

Is Code Refactor MCP server safe?
Mostly: it is graded B (76/100). Read the Code Refactor safety report
How do I install Code Refactor?
It runs remotely at code-refactor-api.app.workbuddy.host. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Code Refactor need an API key?
Yes. The registry entry asks for OPENAI_API_KEY.
Is Code Refactor maintained?
The last commit was 17 days ago (2026-10-18). The latest release is v1.0.4.
Is Code Refactor up?
93% of our last 28 checks got an answer. We check remote servers about four times a day.
How does Code Refactor compare with other MCP servers?
safety score 76/100 (higher than 48% of 48,255 servers); tools 18 (the typical server has 7); tools that change things 6% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
