mcp-flight-search and fli
These are competitors—both implement MCP servers for flight search functionality, offering alternative integrations for the same use case with different underlying APIs (one appears to use a generic realtime flight search provider while the other uses Google Flights).
About mcp-flight-search
arjunprabhulal/mcp-flight-search
MCP Server implementation for the Model Context Protocol (MCP) enabling AI tool usage - Realtime Flight Search
Integrates with SerpAPI Google Flights to enable real-time flight search via MCP tools supporting one-way and round-trip queries with airport codes and flexible dates. Implements an HTTP transport server with structured Pydantic schemas for flight data and modular service architecture separating search logic from API client operations. Designed as a reusable MCP tool that Claude and other compatible AI models can invoke through standardized protocol calls.
About fli

Google Flights MCP and Python Library
Uses reverse-engineered Google Flights API calls instead of web scraping, accessed through both a Python library and an MCP server (stdio and HTTP transports) that exposes `search_flights` and `search_dates` tools. Provides CLI and programmatic interfaces with support for detailed filtering (cabin class, airlines, time windows, stops) and multiple sort options, plus built-in rate limiting and retry logic for reliability.
