fastmcp vs fli
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.; fli: Fli is a powerful Python library and MCP server providing programmatic access to Google Flights data. It leverages reverse-engineered API access for fast, reliable, and modular flight searches, offering both a CLI and a Python API for comprehensive flight search, deal finding, and results filtering.
