## Why advanced_web_search is rated Low

This tool performs web search operations with enhanced filtering and formatting capabilities. It retrieves and queries information from the web without creating, modifying, deleting, or executing arbitrary operations. The 'Sonar direct answer' feature is an optional response generation enhancement, not code execution. No side effects or irreversible actions are possible.

From the tool's own definition: "Tool name 'advanced_web_search' and description indicating it supports 'complex retrieval parameters & result shaping' and optional 'Sonar direct answer' — all characteristics of search and query operations with no data modification, deletion, or code…"

## Use case

AI agents call advanced_web_search to retrieve information from Martin MCP Toolbox without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
