# ToolIndex > Open directory of tools AI agents can use, with source links and clear setup instructions. ToolIndex is an open directory of tools AI agents can use: skills, MCP servers, command-line tools, APIs, libraries, plugins, workflows and harnesses. Each listing links directly to its source and explains access, installation, configuration, licensing and review scope. New community submissions are welcome. Harneloop is optional. Review labels describe specific evidence; they do not guarantee every model/platform. ## Directory - [Catalog](https://toolindex.org/index.md): Overview and available tools. - [About ToolIndex](https://toolindex.org/about/index.md): Definitions, maintainer, review scope and FAQ. - [Submit a tool](https://toolindex.org/submit/index.md): Short issue-first submission process. ## Tool installation and access guides - [Smooth Motion Graphics](https://toolindex.org/tools/smooth-motion-graphics/index.md): A compact skill for calm, clear brand animations. - [ViperMesh for Blender](https://toolindex.org/tools/vipermesh-blender/index.md): A local Blender MCP workflow for building and checking 3D scenes. ## Data - [Machine-readable catalog](https://toolindex.org/catalog.json): Reviewed listings with source, distribution, install steps, manual setup, license and evidence. - [Full text](https://toolindex.org/llms-full.txt): Combined public guide and installation text.
