Search GitHub repositories and return a Markdown report.
AI agents call search_repositories_markdown to retrieve information from Repo Radar MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries GitHub repositories and formats results as Markdown. It retrieves public repository metadata without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal—an agent could only retrieve publicly available information, potentially in volume, but cannot alter state or trigger external actions.
From the tool's definition Tool name 'search_repositories_markdown' and description 'Search GitHub repositories and return a Markdown report' indicate data retrieval with no side effects. The verb 'search' and 'return' are read-only operations.
