Identify the technology stack of a website by analyzing HTTP headers, HTML meta tags, and JavaScript includes. Detects CMS (WordPress, Drupal), frameworks (React, Angular), CDN providers (Cloudflare, Akamai), analytics tools, web servers, and programming languages. Use this for reconnaissance to understand what software a target runs. Returns JSON with a technologies array, each containing name, category, confidence percentage, and version (when detectable). Read-only HTTP request, no authentication required.

Search Vaadin documentation for relevant information about Vaadin development, components, and best practices. Uses hybrid semantic + keyword search. USE THIS TOOL for questions about: Vaadin components (Button, Grid, Dialog, etc.), TestBench, UI testing, unit testing, integration testing, @BrowserCallable, Binder, DataProvider, validation, styling, theming, security, Push, Collaboration Engine, PWA, production builds, Docker, deployment, performance, and any Vaadin-specific topics. When using this tool, try to deduce the correct development model from context: use "java" for Java-based views, "react" for React-based views, or "common" for both. Use get_full_document with file_paths containing the result's file_path when you need complete context.

IMPORTANT: Always use this tool FIRST before working with Vaadin. Returns a comprehensive primer document with current (2025+) information about modern Vaadin development. This addresses common AI misconceptions about Vaadin and provides up-to-date information about Java vs React development models, project structure, components, and best practices. Essential reading to avoid outdated assumptions. For legacy versions (7, 8, 14), returns guidance on version-specific resources.

Identify the technology stack and services used by a website. Returns framework names, CMS platform, JavaScript libraries, analytics services, CDN provider, hosting provider, and security tools detected. Use for competitive analysis, vendor intelligence, or understanding site architecture.

Search the web for any topic and get clean, ready-to-use content. Best for: Finding current information, news, facts, people, companies, or answering questions about any topic. Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people / category:company to search through Linkedin profiles / companies respectively. If highlights are insufficient, follow up with web_fetch_exa on the best URLs.

Get the Courier SDK installation guide for a specific platform. For client-side SDKs (React, iOS, Android, Flutter, React Native), also generates a sample JWT.
