Security scanner for AI agent tool definitions
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.
