search_github_repositories
AI agents call search_github_repositories to retrieve information from Risky Business MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool searches and retrieves data from GitHub repositories without modifying, executing, or deleting anything. It falls clearly into the Read category as a search/query operation. Severity is low because searching public repositories for vulnerability information poses minimal risk even if misused by an AI agent—it only exposes already-public information.
