MCP_SEARCH_ENGINE 说明:
duckduckgo:默认选项,无 API Key;在部分网络环境下可能不可用。bing:默认使用www.bing.com页面检索;可通过MCP_BING_DOMAIN=cn.bing.com切换大陆入口。baidu:使用百度网页检索;中国大陆可用性通常较好。
可选 API Key 模式说明:
当前版本默认使用“网页检索”模式(无需 API Key)。
MCP_SEARCH_API_KEY/MCP_SEARCH_API_ENDPOINT已预留,便于后续接入官方 API 或第三方聚合 API。
可选截图依赖
uv pip install -e ".[screenshot]"
playwright install chromium可选 Web 配置界面
项目内提供了一个基于 Flask 的辅助配置界面(web_config.py / run_web_config.py),用于通过浏览器引导执行 claude mcp add:
uv pip install -e ".[web]"
uv run python run_web_config.py打开 http://localhost:5000 即可使用。
如果你只通过命令行配置 MCP,可忽略这两个文件。
