Skarn for Cursor: audit your AI coding sessions and assistant configs for leaked credentials and risky configuration, and run the pre-execution guard. Backed by the Skarn detection engine on your machine; the skarn binary is installed separately. It declares one local MCP server, named skarn, with four tools (scan_sessions, vet_configs, list_sessions, session_stats): every tool is read-only, none of them writes or changes a file, none of them makes a network call, and every matched value comes back masked.
