DIY ToolsHub — Free Online Tools

About

ToolsHub provides over 35 free online tools for all users, requiring no sign-up or download. It offers PDF tools, converters, calculators, generators, and more. The platform distinguishes itself by using zero paid APIs and being fully MCP-compatible. This means every calculation tool is accessible through the Model Context Protocol, allowing AI assistants such as Claude to directly utilize ToolsHub's tools. It is also designed for SEO, with each tool page featuring structured FAQs, canonical tags, OpenGraph metadata, and a registry-driven sitemap. A REST JSON API is available as well.
