Google 自定义搜索引擎 MCP 服务器
一个模型上下文协议服务器,使用 CSE(自定义搜索引擎)提供搜索功能。该服务器使 LLM 能够提供常规的 Google 搜索词并返回找到的搜索结果。
该工具仅返回结果本身,不包含内容。建议将其与其他服务器(例如mcp-server-fetch)结合使用,以便从搜索结果中提取内容。您也可以将其与其他工具结合使用,以实现某种“深度搜索”或工具链式功能。
免费配额为每天 100 次搜索(1 次工具调用 == 1 次搜索),如果您不想设置计费并且这不足以满足您的使用情况,您应该考虑使用其他服务器。
可用工具
google_search
- 使用搜索词搜索自定义搜索引擎并返回包含每个结果的标题、链接和片段的结果列表。search_term
(字符串,必需):要搜索的搜索词,相当于通常的 Google 搜索中的查询参数q
。
环境变量
API_KEY
(必需):自定义搜索引擎的 API 密钥。ENGINE_ID
(必需):自定义搜索引擎的引擎 ID。SERVICE_NAME
(必需/可选):服务名称,如果您没有更改名称(自定义搜索),则留空。COUNTRY_REGION
(可选):将搜索结果限制为来自特定国家/地区的文档。请参阅国家/地区参数值以了解有效值。GEOLOCATION
(可选,默认为“us”):执行搜索的最终用户的地理位置。请参阅地理位置参数值以了解有效值。RESULT_LANGUAGE
(可选,默认为“lang_en”):搜索结果的语言。请参阅自定义搜索引擎查询参数 lr了解有效值。RESULT_NUM
(可选,默认 10):返回的搜索结果数量。范围为 1-10。
CSE 设置
创建自定义搜索引擎相对容易,完全免费,并且可以在 5 分钟内完成。
- 前往https://console.cloud.google.com/并创建一个新项目。例如,命名为“Claude CSE”。
- 选择项目并在搜索栏中搜索“自定义搜索 API”。
- 点击搜索结果,点击“启用”。
- 单击“凭据”选项卡并创建一个新的 API 密钥。
- 前往https://programmablesearchengine.google.com创建一个新的自定义搜索引擎。
- 创建一个新的搜索引擎并赋予它任意名称,该名称与SERVICE_NAME无关。
- 如果您想要正常的 Google 搜索体验,请选择“搜索整个网络”。
- 单击“创建”并从 js 代码中复制引擎 ID,或点击自定义并从概览中获取它。
- 您可以根据自己的喜好随意定制搜索引擎。
使用默认配额,您每天可免费获得 100 次搜索。例如,即使您获得 10 条结果,每次工具调用也仅需支付 1 次搜索的费用。
安装
使用 uv(推荐)
使用uv
时无需特殊安装。我们将使用uvx
直接运行mcp-google-cse 。
使用 PIP
或者,您可以通过 pip 安装mcp-google-cse
:
pip install mcp-google-cse
安装后,您可以使用以下命令将其作为脚本运行:
通过 Smithery 安装
要通过Smithery自动为 Claude Desktop 安装 Google 自定义搜索引擎:
npx -y @smithery/cli install @Richard-Weiss/mcp-google-cse --client claude
配置
为 Claude 应用程序配置
添加到您的claude_desktop_config.json
:
使用 uvx(如果你不知道选择哪一个,请使用这个)
"mcp-google-cse": {
"command": "uvx",
"args": ["mcp-google-cse"],
"env": {
"API_KEY": "",
"ENGINE_ID": ""
}
}
使用 pip 安装
"mcp-google-cse": {
"command": "python",
"args": ["-m", "mcp-google-cse"],
"env": {
"API_KEY": "",
"ENGINE_ID": ""
}
}
本地运行
"mcp-google-cse": {
"command": "uv",
"args": [
"--directory",
"{{Path to the cloned repo",
"run",
"mcp-google-cse"
],
"env": {
"API_KEY": "",
"ENGINE_ID": ""
}
}
