Service status — Free. Is a listed service up right now? Its state (up, degraded or down), since when, the latest check, uptime over 24 hours, 7 and 30 days, and recent outages, from ToolVet's own checks.
Scan an MCP server — Free. Connects to a remote MCP server (Streamable HTTP) the way an agent would, reads its tool definitions and instructions (up to a size limit) without calling any tool, and checks them for tool poisoning: hidden instructions, invisible characters, requests for credential files and more. Returns a grade A to F with findings, and says when part of the definitions was too large to check. Limited per IP.
