fastmcp vs bilig
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.; bilig: bilig is a headless workbook runtime for TypeScript. It allows Node.js services, agent tools, and serverless functions to use spreadsheet formulas and workbook state programmatically without a visual interface. It features formula evaluation, persistence, round-trip verification, and MCP support.
