IO Tools 3.0 (Revamp) - 900+ free tools and growing, redesigned - now with API + MCP

by•
IO Tools is a free tools platform - 900+ utilities for everyday tasks, no signup needed. 3.0 is a full rebuild: redesigned UI, faster load times across the board, and a public API + MCP server so you can plug IO Tools straight into your AI agent workflows instead of opening a browser tab. We've grown from ~40 to 700+ daily clicks. This release is about making that same toolkit usable anywhere - browser, API, or agent.

Hey Product Hunt 👋 We built IO Tools because we were tired of googling "json formatter" and "uuid generator" for the tenth time in a day. It's 900+ free utilities, no signup. 3.0 is the biggest update yet - redesigned the whole UI, made everything faster, and shipped a public API + MCP server so the tools work inside your AI agent, not just your browser tab. Would love your feedback, especially on the new API. What tools should we add next?
