Package Documentation MCP Server

简介

MCP 包文档服务器为多种编程语言（Go、Python、JavaScript/TypeScript、Rust）提供高效的包文档访问，并支持语言服务器协议(LSP)功能。

安装

npx -y mcp-package-docs

通过 Smithery 安装 (Claude Desktop):

npx -y @smithery/cli install mcp-package-docs --client claude

配置

添加到你的 MCP 设置配置中:

{
  "mcpServers": {
    "package-docs": {
      "command": "npx",
      "args": ["-y", "mcp-package-docs"],
      "env": {
        "ENABLE_LSP": "true"  // 可选：启用语言服务器协议支持
      }
    }
  }
}

核心功能

文档查询工具

1. Go 包文档

   {
     "name": "describe_go_package",
     "arguments": {
       "package": "encoding/json",
       "symbol": "Marshal"
     }
   }
   

2. Python 包文档

   {
     "name": "describe_python_package",
     "arguments": {
       "package": "requests",
       "symbol": "get"
     }
   }
   

3. NPM 包文档 (支持私有注册表)

   {
     "name": "describe_npm_package",
     "arguments": {
       "package": "axios",
       "version": "1.6.0"
     }
   }
   

4. Rust 箱文档

   {
     "name": "describe_rust_package",
     "arguments": {
       "package": "serde",
       "version": "1.0.219"
     }
   }
   

5. 文档搜索

   {
     "name": "search_package_docs",
     "arguments": {
       "package": "requests",
       "query": "authentication",
       "language": "python",
       "fuzzy": true
     }
   }
   

LSP 功能 (当 ENABLE_LSP=true)

• 悬停文档
• 代码补全
• 代码诊断

在 LLM 中使用示例

// 查找 Python 文档
const pythonDocResult = await use_mcp_tool({
  server_name: "package-docs",
  tool_name: "describe_python_package",
  arguments: {
    package: "requests",
    symbol: "post"
  }
});

// 在文档中搜索
const searchResult = await use_mcp_tool({
  server_name: "package-docs",
  tool_name: "search_package_docs",
  arguments: {
    package: "serde",
    query: "serialize",
    language: "rust"
  }
});
