fastmcp vs ThinkWatch

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.; ThinkWatch: ThinkWatch is a unified gateway for AI API and MCP tool access, providing authentication, authorization, rate limiting, auditing, and cost tracking. It secures API keys, enables visibility, and enforces compliance for AI usage across an organization.
