Get detailed information about a specific card
AI agents call get_card to retrieve information from Superthread Mcp Extended without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves card information without creating, modifying, or deleting data. It is a straightforward read operation that queries existing state. The low severity reflects minimal blast radius—misuse would only expose information already stored in the system, not cause destructive or irreversible changes.
