tooltrust-scanner vs FastMCP
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.; FastMCP: FastMCP is a Python framework that simplifies the creation of applications adhering to the Model Context Protocol (MCP), enabling AI agents to connect seamlessly with tools and data. It streamlines complex protocol implementation, focusing on delivering the right information to agents at the right time.
