Search the web using DuckDuckGo.
AI agents call tool_search_web to retrieve information from DevLens MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs web search, which is a read-only operation that retrieves publicly available information. It has no side effects, cannot modify data, and poses minimal security risk. The severity is low because search results are informational and cannot cause harm through misuse.
From the tool's definition Tool description states 'Search the web using DuckDuckGo' - a query/search operation that retrieves information without modifying, deleting, or executing operations on external systems.
