tooltrust-scanner vs Sentinelgate

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.; Sentinelgate: SentinelGate is a self-hosted, container-native, zero-lock-in proxy that intercepts every action of an AI agent before it executes, applying deterministic rules to block unauthorized tool calls, shell commands, and file operations. It provides a full audit trail, content scanning, and session-aware policies, and works with any MCP-compatible client or sandbox.
