该工具本质是对 Exa /search 端点的 type: "fast" 调用，无代码专属索引，官方建议直接使用 web_search_exa 替代。用户仍可通过环境变量 ENABLED_TOOLS 强制启用，但默认不会注册到 MCP server。

This tool is essentially a type: "fast" call to the Exa /search endpoint with no code-specific index. The official recommendation is to use web_search_exa instead. Users can still force-enable it via the ENABLED_TOOLS environment variable, but it is not registered on the MCP server by default.
