软件包文档 MCP 服务器
MCP（模型上下文协议）服务器为 LLM 提供跨多种编程语言和语言服务器协议 (LSP) 功能对包文档的有效访问。
特征
多语言支持：
通过
go doc获取 Go 软件包通过内置
help()Python 库通过注册表文档（包括私有注册表）的 NPM 包
通过 crates.io 和 docs.rs 获取 Rust 板条箱
智能文档解析：
包含描述、用法和示例的结构化输出
重点突出的信息，避免上下文过载
支持特定符号/函数查找
跨文档的模糊和精确搜索功能
高级搜索功能：
在包文档中搜索
模糊匹配，灵活查询
具有相关性评分的上下文感知结果
从搜索结果中提取符号
语言服务器协议（LSP）支持：
代码符号的悬停信息
代码补全
诊断（错误和警告）
目前支持 TypeScript/JavaScript
可扩展至其他语言
性能优化：
内置缓存
高效解析
最小内存占用
安装
npx -y mcp-package-docs
通过 Smithery 安装
要通过Smithery自动安装 Claude Desktop 的 Package Docs：
npx -y @smithery/cli install mcp-package-docs --client claude
用法
作为 MCP 服务器
添加到您的 MCP 设置配置：
{
"mcpServers": {
"package-docs": {
"command": "npx",
"args": ["-y", "mcp-package-docs"],
"env": {
"ENABLE_LSP": "true" // Optional: Enable Language Server Protocol support
}
}
}
}
LSP 功能包括通用语言服务器的默认配置：
TypeScript/JavaScript：
typescript-language-server --stdioHTML：
vscode-html-language-server --stdioCSS：
vscode-css-language-server --stdioJSON：
vscode-json-language-server --stdio
如果需要，您可以覆盖这些默认值：
{
"mcpServers": {
"package-docs": {
"command": "npx",
"args": ["-y", "mcp-package-docs"],
"env": {
"ENABLE_LSP": "true",
"TYPESCRIPT_SERVER": "{\"command\":\"/custom/path/typescript-language-server\",\"args\":[\"--stdio\"]}"
}
}
}
}
该服务器提供以下工具：
lookup_go_doc / describe_go_package
获取 Go 包文档
{
"name": "describe_go_package",
"arguments": {
"package": "encoding/json", // required
"symbol": "Marshal" // optional
}
}
lookup_python_doc / describe_python_package
获取 Python 包文档
{
"name": "describe_python_package",
"arguments": {
"package": "requests", // required
"symbol": "get" // optional
}
}
describe_rust_package
从 crates.io 和 docs.rs 获取 Rust crate 文档
{
"name": "describe_rust_package",
"arguments": {
"package": "serde", // required: crate name
"version": "1.0.219" // optional: specific version
}
}
搜索包文档
在包文档中搜索
{
"name": "search_package_docs",
"arguments": {
"package": "requests", // required: package name
"query": "authentication", // required: search query
"language": "python", // required: "go", "python", "npm", "swift", or "rust"
"fuzzy": true // optional: enable fuzzy matching (default: true)
}
}
lookup_npm_doc / describe_npm_package
从公共和私有注册表获取 NPM 包文档。根据您的 .npmrc 配置自动使用适当的注册表。
{
"name": "describe_npm_package",
"arguments": {
"package": "axios", // required - supports both scoped (@org/pkg) and unscoped packages
"version": "1.6.0" // optional
}
}
该工具读取您的 ~/.npmrc 文件以确定每个包的正确注册表：
使用范围注册表配置（例如，@mycompany：registry = ...）
支持私有注册表（GitHub Packages、GitLab、Nexus、Artifactory 等）
如果没有配置自定义注册表，则回退到默认 npm 注册表
.npmrc 配置示例：
registry=https://nexus.mycompany.com/repository/npm-group/
@mycompany:registry=https://nexus.mycompany.com/repository/npm-private/
@mycompany-ct:registry=https://npm.pkg.github.com/
语言服务器协议 (LSP) 工具
启用 LSP 支持后，以下附加工具将可用：
获取悬停
获取文档中某个位置的悬停信息
{
"name": "get_hover",
"arguments": {
"languageId": "typescript", // required: language identifier (e.g., "typescript", "javascript")
"filePath": "src/index.ts", // required: path to the source file
"content": "const x = 1;", // required: content of the file
"line": 0, // required: zero-based line number
"character": 6, // required: zero-based character position
"projectRoot": "/path/to/project" // optional: project root directory
}
}
获取完成信息
获取文档中某个位置的完成建议
{
"name": "get_completions",
"arguments": {
"languageId": "typescript", // required: language identifier
"filePath": "src/index.ts", // required: path to the source file
"content": "const arr = []; arr.", // required: content of the file
"line": 0, // required: zero-based line number
"character": 16, // required: zero-based character position
"projectRoot": "/path/to/project" // optional: project root directory
}
}
获取诊断
获取文档的诊断信息（错误、警告）
{
"name": "get_diagnostics",
"arguments": {
"languageId": "typescript", // required: language identifier
"filePath": "src/index.ts", // required: path to the source file
"content": "const x: string = 1;", // required: content of the file
"projectRoot": "/path/to/project" // optional: project root directory
}
}
LLM 中的使用示例
查找文档
// Looking up Go documentation
const goDocResult = await use_mcp_tool({
server_name: "package-docs",
tool_name: "describe_go_package",
arguments: {
package: "encoding/json",
symbol: "Marshal"
}
});
// Looking up Python documentation
const pythonDocResult = await use_mcp_tool({
server_name: "package-docs",
tool_name: "describe_python_package",
arguments: {
package: "requests",
symbol: "post"
}
});
// Looking up Rust documentation
const rustDocResult = await use_mcp_tool({
server_name: "package-docs",
tool_name: "describe_rust_package",
arguments: {
package: "serde"
}
});
// Searching within documentation
const searchResult = await use_mcp_tool({
server_name: "package-docs",
tool_name: "search_package_docs",
arguments: {
package: "serde",
query: "serialize",
language: "rust",
fuzzy: true
}
});
// Using LSP for hover information (when LSP is enabled)
const hoverResult = await use_mcp_tool({
server_name: "package-docs",
tool_name: "get_hover",
arguments: {
languageId: "typescript",
filePath: "src/index.ts",
content: "const axios = require('axios');\naxios.get",
line: 1,
character: 7
}
});
