Used for HTML parsing and manipulation when processing HTML documents in the knowledge base system.
Referenced for repository management in the project configuration.
Used as the repository hosting service for the project as specified in the configuration.
Used as the package manager for installing dependencies and running scripts.
Used as the implementation language for the MCP server, providing type safety and modern JavaScript features.
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 Knowledge Base Serverquery the knowledge base for information about document processing"

}安装
克隆项目并安装依赖：
npm install构建项目：
npm run build使用方法
1. 启动服务器
npm start2. 在 MCP 客户端中配置
在你的 MCP 客户端配置文件中添加：
{
"mcpServers": {
"knowledge-base": {
"command": "node",
"args": ["dist/index.js"],
"env": {}
}
}
}3. 可用的工具
