A server providing access to NCBI E-utilities API for searching and retrieving data from databases like PubMed, Protein, and Nucleotide.
README
NCBI E-utilities MCP 服务器
用于访问 NCBI E-utilities API 的MCP服务器。该包提供对 NCBI 数据库(包括 PubMed、Protein、Nucleotide 等)的程序化访问。
功能特性
- EInfo: 获取 Entrez 数据库列表或特定数据库的统计信息
- ESearch: 基于文本的搜索,从 NCBI 数据库检索 UID 列表
- ESummary: 检索指定 UID 的文档摘要(DocSum)
- EFetch: 获取指定 UID 的完整格式化记录(核心功能)
连接到您的 MCP 客户端
您可以使用uvx命令从本地 MCP 客户端连接到您的 NCBI MCP 服务器。
要从 Claude Desktop 或其他兼容 MCP 的客户端连接到您的 MCP 服务器,请按照 MCP 客户端设置指南并更新客户端配置。
使用以下配置更新您的 MCP 客户端配置:
{
"mcpServers": {
"ncbi-mcp": {
"command": "uvx",
"args": [
"ncbi-mcp"
],
"env": {
"API_KEY": "YOUR_NCBI_API_KEY"
}
}
}
}
注意: 不提供 API 密钥时,您的请求被限制为每秒最多 3 次。提供 API 密钥后,您可以每秒发出多达 10 个请求。
获取 NCBI API 密钥
要获取 NCBI API 密钥,您需要:
- 在 https://www.ncbi.nlm.nih.gov/account/ 注册 NCBI 账户
- 前往您的账户"设置"页面
- 找到"API 密钥管理"区域并点击"创建 API 密钥"
- 复制生成的密钥并在您的
.env文件中使用
