toolbox vs fastmcp
toolbox: Sectool is a collaborative workbench for application security testing, not a scanner. It combines your ability to handle UI and stateful APIs with an agent's strength in analyzing and mutating traffic through a proxy. Together, you can perform more thorough testing with less effort.; fastmcp: FastMCP is a standard framework for building Model Context Protocol (MCP) applications, which connect LLMs to tools and data. It simplifies the process by automatically generating schemas, validation, and documentation for tools, and managing transport negotiation and authentication for server connections. FastMCP offers a comprehensive solution for developing, deploying, and scaling MCP-powered systems.
