fastmcp vs zscaler-mcp-server

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.; zscaler-mcp-server: The Zscaler MCP Server provides over 300 tools for managing Zscaler services (ZIA, ZPA, ZDX, etc.) via the Model Context Protocol. It features a security-first design with read-only mode by default and mandatory allowlist for write operations, supporting multiple transports and authentication methods.
