## Description

This MCP server implementation provides a bridge between Claude Desktop and Clerk-protected API routes or server actions. Developed by Sokratis Vidros, it allows an AI assistant to impersonate a Clerk user, enabling secure interactions with authenticated endpoints. Built using TypeScript and Cloudflare Workers, the implementation focuses on maintaining user authentication while facilitating AI-driven operations. It's particularly useful for scenarios where AI assistants need to interact with protected resources, such as personalized data retrieval or secure API interactions, within applications that use Clerk for authentication.
