aura vs fastmcp
aura: Aura is a production-ready framework for building AI agents using TOML configuration. It supports multi-provider LLM, dynamic MCP tool discovery, RAG pipelines, and serves an OpenAI-compatible API. The framework is built on Rig.rs with enhancements for reliability and operability.; 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.
