## Why get_tech_stack is rated Low

The tool appears to retrieve or query tech stack information from a website UI, consistent with other read-only analysis tools on this server. However, confidence is moderate (0.7) due to empty description; severity is medium rather than low because web reconnaissance (identifying technology stacks) can inform targeted attacks, though the tool itself has no direct side effects.

From the tool's own definition: "Tool name 'get_tech_stack' suggests querying technology information from a website. Server description indicates tools analyze website UIs using Playwright and provide data extraction; sibling tools like 'analyze_page', 'get_dom_overview',…"

## Use case

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