MCP tool that launch search with DuckDuckGo
AI agents call search_web_with_duckduckgo to retrieve information from Tagny 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 and retrieves search results from DuckDuckGo without creating, modifying, deleting, or executing any operations. It is a passive information retrieval mechanism analogous to performing a web search in a browser. The blast radius of misuse is minimal—an agent could retrieve unwanted information but cannot cause side effects beyond data access.
From the tool's definition Tool description states it 'launch search with DuckDuckGo' and server description emphasizes 'web search' and 'URL text fetching' with 'real-time web access.' No evidence of modification, deletion, execution, or financial operations.
