I made MCP (Model Context Protocol) alternative solution, for OpenAI and all other LLMs, that is cheaper than Anthropic Claude

The author developed an alternative solution utilizing LLM Function Calling, TypeScript, and Swagger/OpenAPI to replace the MCP (Model Context Protocol) of Anthropic Claude with smaller models like gpt-4o-mini. The solution leverages validation feedback strategies to improve function calling success rates and integrates Agentica AI framework for efficient multi-agent orchestration.
