onetool-mcp vs fli

onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; 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.
