Search the web and return only the search result snippets/descriptions without following links to extract full page content. This is a lightweight alternative to full-web-search for when you only need brief search results. For comprehensive information, use full-web-search instead.
AI agents call get-web-search-summaries to retrieve information from Web Search MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries web search engines and returns summarized results. It retrieves data without modifying, executing commands, deleting, or performing any irreversible actions. The low severity reflects minimal blast radius—an AI agent misusing this can only retrieve publicly available information, with no capacity to affect external systems or data.
From the tool's definition Tool returns 'search result snippets/descriptions' and 'only the search result snippets' without 'following links to extract full page content.' This is explicitly a retrieval operation with no side effects.
