lunar vs mcp-fusion
lunar: Lunar.dev is an open-source platform designed to manage, govern, and optimize third-party API consumption for applications and AI agent workloads at scale. It acts as a unified API Gateway for the AI era, providing a crucial mediation layer between applications, agents, and external services.; mcp-fusion: `mcp-fusion` is an advanced TypeScript framework designed to consolidate numerous Model Context Protocol (MCP) operations into a single, intelligent LLM tool. It addresses context exhaustion and routing confusion by utilizing build-time multiplexing and context gating for scalable, precise API interactions.
