wren-engine vs fastmcp

wren-engine: Wren Engine is an open context engine for AI agents that transforms business data into agent-usable context. It captures business definitions, metrics, relationships, and access rules, enabling agents to understand models and generate accurate queries. The engine supports MCP, HTTP APIs, and can be embedded into various agent workflows.; 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.
