The world's first WebMCP-enabled tools platform. 170+ free tools that AI agents can discover, fill, and use automatically. Private, secure, instant.
FastTools is the first platform where AI agents can use every tool autonomously. Powered by the Web Model Context Protocol (WebMCP), AI agents in Chrome 146+ can discover all 170+ tools, fill forms, trigger calculations, and read structured results — all without human intervention.
AI agents follow a simple workflow: Discover tools via our API endpoint, Describe available inputs on any tool page, Fill fields including dropdowns, switches, and toggles, then Click & Read to trigger actions and capture results. Realtime tools like the temperature converter skip the click step entirely.
Every new tool added to FastTools is automatically WebMCP-compatible. Our architecture auto-discovers fields from the DOM, detects the interaction mode, and registers the tool with the browser's AI agent API — no per-tool configuration required.
AI agents discover all 170+ tools from a single endpoint with input schemas, interaction modes, and categories — before visiting any page.
Button-click, realtime, generator, file-upload, and API-dependent — each tool type has optimized handling so agents know exactly when to click, wait, or read.
Agents can fill Radix selects, toggle switches, click radio groups, and interact with every custom component — not just native HTML inputs.
FastTools isn't just another collection of scripts. It's a comprehensive, privacy-first productivity platform designed to streamline your daily workflow. Whether you're a developer debugging JSON, a designer converting colors, or a content creator generating viral hashtags, our tools are engineered for speed and precision.
Unlike other platforms that upload your sensitive data to remote servers, FastTools performs 95% of operations right in your browser. When you use our PDF splitter or JSON converter, your files never leave your device. This "Local-First" architecture ensures enterprise-grade security for your data.
We've obsessed over every millisecond. By removing bloated frameworks and tracking scripts, we deliver results instantly. Our tools are optimized for Core Web Vitals, ensuring seamless performance even on slow mobile connections.
We don't track your inputs or save your files. Your session data vanishes the moment you close the tab.
All traffic is secured with banking-grade SSL encryption, ensuring your connection is always safe.
No hidden subscriptions, no "Pro" tiers, and no credit card required. Just free, powerful tools.
