tooltrust-scanner vs McpVanguard

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.; McpVanguard: McpVanguard is a security gateway for MCP agents that inspects traffic in real time and enforces security policy before sensitive calls reach the underlying tool. It works in local-first mode wrapping stdio MCP servers and in gateway mode exposing hardened SSE and Streamable HTTP endpoints. Transparent integration without rewriting existing MCP servers.
