OSIM MCP Server

Python FastMCP

基于 FastMCP 的 Model Context Protocol (MCP) 服务器,提供 OSIM (Open Security Information Model) 数据标准 schema 的查询和访问能力。

🚀 快速开始

使用 uvx(推荐,无需安装)

包已发布到 PyPI,可以直接使用 uvx 运行:

uvx osim-mcp-server

在 MCP 客户端中配置

Claude Desktop

在配置文件(~/Library/Application Support/Claude/claude_desktop_config.json)中添加:

{
  "mcpServers": {
    "osim-mcp-server": {
      "command": "uvx",
      "args": ["osim-mcp-server"]
    }
  }
}

Cursor

在 MCP 设置中添加:

{
  "mcpServers": {
    "osim-mcp-server": {
      "command": "uvx",
      "args": ["osim-mcp-server"]
    }
  }
}

从源码运行

# 克隆仓库
git clone https://github.com/osim-group/osim-mcp-server.git
cd osim-mcp-server

# 首先获取 schemas(必需)
# 确保已安装 git
python update_schemas.py

# 安装依赖并运行
uv sync
uv run python server.py

重要:仓库本身不包含 schemas 目录,需要先运行 update_schemas.py 获取 schemas 文件才能正常运行。

更新 Schemas

项目中的 schemas 文件来源于 OSIM Schema 仓库。如果需要获取或更新最新的 schemas,可以使用项目提供的更新脚本:

# 确保已安装 git
python update_schemas.py

脚本会自动:

  • 从 GitHub 仓库克隆最新的 schemas
  • 备份现有的 schemas(如果存在)
  • 更新本地 schemas 目录
  • 验证更新结果

注意:更新脚本需要系统已安装 git 命令。

📚 功能特性

MCP 工具

  1. list_schema_names - 列出所有可用的数据标准 schema 名称

    • 返回格式:{group}.{category}.{title}
    • 示例:log.network_session_audit.http_audit
  2. describe_schemas - 获取指定 schema 的描述信息

    • 参数:schema_names (List[str])
    • 返回:字典,键为 schema 名称,值为描述信息
  3. get_schema - 获取指定 schema 的完整字段定义

    • 参数:schema_path (str),格式为 {group}.{category}.{title}
    • 返回:字段定义字典,包含字段名、标签、类型、要求、描述等信息

MCP 资源

通过资源 URI 访问 schema 文件内容:

  • URI 格式data-standard://{group}/{category}/{title}
  • 示例
    • data-standard://log/network_session_audit/http_audit
    • data-standard://alert/network_attack/apt_attack
    • data-standard://asset/business_asset/web_application

📊 数据标准分类

项目提供完整的 OSIM 数据标准支持,包括:

  • 告警 (Alert):异常行为、数据安全、恶意软件、网络攻击等
  • 资产 (Asset):业务资产、云资产、数据资产、网络资产等
  • 日志 (Log):账户操作审计、数据安全审计、主机行为审计、网络会话审计等
  • 事件 (Incident):安全事件记录和分类
  • 设备检测 (Device Detection):EDR、防火墙、WAF、IDS/IPS 等各类安全设备

数据来源:所有 schema 文件均来源于 OSIM Schema 仓库

🛠️ 开发

获取/更新 Schemas

项目提供了脚本用于从 GitHub 仓库同步最新的 schemas:

python update_schemas.py

注意:构建分发包前需要先获取 schemas,因为分发包需要包含 schemas 文件。

构建分发包

# 确保已获取 schemas
python update_schemas.py

# 构建分发包
uv build

发布到 PyPI

# 安装 twine
uv pip install twine

# 上传到 PyPI
uv run twine upload dist/*

发布后即可通过 uvx osim-mcp-server 使用。

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
