README

Semantic Scholar MCP Server

npm version

一个 MCP (Model Context Protocol) 服务器,提供 Semantic Scholar 学术搜索功能。

功能特性

  • 论文搜索、详情查询、引用分析
  • 作者搜索和学术档案查询
  • 基于论文的智能推荐
  • 支持多种论文 ID 格式 (DOI, ArXiv, PMID 等)
  • 内置速率限制和自动重试机制

快速开始

在 Claude Desktop 中使用

编辑配置文件:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
  • Windows: %APPDATA%\Claude\claude_desktop_config.json
{
  "mcpServers": {
    "semanticscholar": {
      "command": "npx",
      "args": ["-y", "@xbghc/semanticscholar-mcp"],
      "env": {
        "SEMANTIC_SCHOLAR_API_KEY": "your-api-key"
      }
    }
  }
}

配置 API Key (可选)

Semantic Scholar API 可以无需认证使用,但有速率限制。申请 API Key 可获得更高的请求配额。

  1. 访问 Semantic Scholar API 申请 API Key
  2. 在配置中设置 SEMANTIC_SCHOLAR_API_KEY 环境变量

可用工具
