SmartBW MCP
Vaultwarden/Bitwarden MCP 代理 — 让 AI 安全获取密码和 API Key
SmartBW MCP 是一个 MCP (Model Context Protocol) 工具服务器,让 AI Agent 通过标准 MCP 接口安全访问你的 Vaultwarden/Bitwarden 密码库。
架构
smartbw_mcp_server.py ← MCP 工具层(8 个工具,AI 零门槛调用)
│
smart_search.py ← 智能搜索层(6 策略模糊搜索 + 索引加速)
│
mcp_raw.py ← 通信层(JSON-RPC + 熔断保护)
│
mcp_daemon.py ← 守护进程层(Unix Socket 常驻 + 自愈)
│
@bitwarden/mcp-server (Node.js) ← 协议层(Bitwarden 官方 MCP Server)
│
Vaultwarden 服务器 ← 数据层
快速开始
1. 安装依赖
npm install -g @bitwarden/cli @bitwarden/mcp-server
pip install cryptography
2. 配置
cp config.example.json ~/.config/bitwarden-mcp/config.json
# 编辑 config.json,填入你的 Vaultwarden 信息
config.json 示例:
{
"bw_host": "https://your-vaultwarden.example.com",
"email": "user@example.com",
"master_password": "YourMasterPassword",
"client_id": "",
"client_secret": ""
}
也可使用环境变量
BW_HOST、BW_EMAIL、BW_MASTER_PASSWORD替代配置文件。
3. 启动守护进程
# 一键安装(含 systemd 服务或后台进程)
bash install.sh
# 或手动启动
python3 mcp_daemon.py
4. 配置 MCP 客户端
在你的 MCP 客户端中添加:
{
"mcpServers": {
"smartbw": {
"command": "python3",
"args": ["/path/to/smartbw_mcp_server.py"]
}
}
}
MCP 工具
| 工具 | 功能 |
|---|---|
smartbw_get_api |
一行获取 API Key(自动搜索 API 字段) |
smartbw_get_password |
获取密码 |
smartbw_get_field |
获取任意自定义字段 |
smartbw_get_item |
获取项目完整信息 |
smartbw_search |
模糊搜索(名称/用户名/自定义字段) |

核心特性
- 模糊搜索: 6 种评分策略,名称/用户名/自定义字段全覆盖,支持错别字容错
- 索引加速: 首次加载后构建名称索引,精确/前缀匹配 O(1)
- 熔断保护: 连续 5 次失败 → 30s 冷却,防止雪崩
- 线程安全: socket 收发原子锁 + 缓存双重检查锁
- 自愈: 守护进程每 60s 健康检查,session 过期自动恢复
- 凭证加密: 主密码自动 Fernet 加密存储,密钥绑定本机指纹
安全
- Unix Socket 权限
0o600(umask + chmod 双重保护) - 密码/API Key 通过 Vaultwarden 管理,不落盘
- 配置文件中的敏感字段自动加密(
!enc:v1:...) - 加密密钥绑定本机,配置文件不可跨机器复制
配置参考
| 配置项 | 环境变量 | 说明 |
|---|---|---|
