Search for text pattern in files using grep
AI agents call search_in_files to retrieve information from MCP File & Git Manager Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only searches and retrieves data from files without creating, modifying, deleting, or executing operations. It falls squarely into the Read category. The severity is low because misuse would only expose information already accessible to the agent's file permissions, with no destructive or execution risk.
