mcp-macclean
Allows cleaning of npm cache (e.g., ~/.npm/_cacache) by discovering, previewing, and optionally deleting cache files.
Allows cleaning of pnpm store cache (with force_store mode for deletion) and provides cache reporting.
Allows cleaning of yarn cache directory by discovering, previewing, and optionally deleting cache files.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@mcp-maccleanpreview my npm and pip caches"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
mcp-macclean
本机多包管理器缓存清理 MCP 服务。
支持统一发现、预览并(经确认后)清理:
mavenpnpmnpmyarnpipuvgo
默认安全策略:只预览,不删除。真正删除需要同时满足:
调用
execute_cleanup时confirm=true.env中MACCLEAN_ALLOW_EXECUTE=true
安装
python3 -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"Related MCP server: Local AI MCP
配置
cp .env.example .env按需编辑 .env。关键项:
配置 | 含义 | 默认 |
| 是否允许真实删除 |
|
| 默认 targets | 全部 |
| Maven 本地仓库父目录(含 |
|
| npm cache 根目录 |
|
| yarn cache,空则自动探测 | 空 |
| pnpm store,空则自动探测 | 空 |
| pip cache,空则自动探测 | 空 |
| uv cache,空则自动探测 | 空 |
| Go module cache | 空 |
| Go build cache | 空 |
| 默认是否清理 Go mod |

| 默认是否清理 Go build |

MCP 注册示例
Claude Code / MCP client 配置示例:
{
"mcpServers": {
"macclean": {
"command": "/绝对路径/mcp-macclean/.venv/bin/python",
"args": ["-m", "macclean.server"],
"cwd": "/绝对路径/mcp-macclean"
}
}
}注意:
必须使用虚拟环境里的 Python(或已
pip install -e .的解释器),不要写裸的python。在本机若python指向 pyenv 的 2.7,会立刻No module named macclean,MCP 表现为Connection closed。command与cwd请写绝对路径;~在部分 MCP 客户端中不会展开。
也可使用 venv 入口脚本:
.venv/bin/macclean工具说明
list_caches
发现缓存位置与占用。
参数:
targets:可选,如["maven","uv"]path:可选,仅单 target 时作为自定义路径
plan_cleanup
生成删除计划,不会删除任何文件。
参数:
targetspathoptions:mode:default|force_store(pnpm)go_mod/go_buildretain_latest(maven)
候选 path 为相对该 target 缓存根的路径,便于浏览与筛选,例如 Maven:
缓存根:
~/.m2/repository候选:
com/example/demo/1.0.0-SNAPSHOT
execute_cleanup
执行清理。
参数:
confirm:必须为truetargets/path/options
若 MACCLEAN_ALLOW_EXECUTE=false 或未确认,将拒绝执行。
成功执行后会返回真实删除统计(删除前实测,非 plan 预估):
字段 | 含义 |
| 删除的候选根目录/条目数 |
| 真实删除的文件数 |
| 真实回收体积 |
| 每项: |
| 该 target 真实删除文件数 |
各 target 策略摘要
target | 默认策略 |
maven | 每个 |
npm | 清理 |
yarn | 清理 yarn cache 内容 |
pnpm | 默认只报告; |
pip | 清理 pip cache 内容 |
uv | 清理 uv cache 内容 |
go | 默认清理 build cache;mod 需显式开启 |
开发
source .venv/bin/activate
pytest -v安全提示
先
plan_cleanup,确认候选后再执行。生产/共享机器上保持
MACCLEAN_ALLOW_EXECUTE=false,仅在明确需要时打开。Maven 清理按版本新旧,不分析项目是否仍引用旧版本。
pnpm 默认保守,避免误删导致大规模重下。
