tooltrust-scanner vs node9-proxy

tooltrust-scanner: ToolTrust Scanner is a static security scanner that analyzes MCP tool definitions before your agent trusts them. It assigns a trust grade (A–F) based on 16+ static rules, covering prompt injection, privilege escalation, and supply chain attacks. It can be used as an MCP server, CLI tool, or CI check.; node9-proxy: Node9 is an execution security layer for AI agents that intercepts dangerous shell commands and tool calls in real-time. It features a multi-channel approval system (native popup, browser, Slack, terminal), a flight recorder for live monitoring, and an AI negotiation loop to guide safer behavior. It also includes DLP content scanning and shadow git snapshots for undo.
