This file provides a NAVIGATION GUIDE ONLY. Before implementing any MCP server features, you MUST: Do NOT rely solely on the quick reference examples in this file - they are minimal examples only. The reference files contain critical best practices, security considerations, and advanced patterns. Comprehensive guide for building production-ready MCP servers with tools, resources, prompts, and widgets using mcp-use. Before doing anything else, determine whether you are inside an existing mcp-use project. Detection: Check the workspace for a package.json that lists "mcp-use" as a dependency, OR any .ts file that imports from "mcp-use/server" . NEVER manually create MCPServer boilerplate, package.json , or project structure by hand. The CLI sets up TypeScript config, dev scripts, inspector integration, hot reload, and widget compilation that are difficult to replicate manually.
