ontology

ontology extends your AI assistant with the ability to typed knowledge graph for structured agent memory and composable skills. Use when creating/querying entities (Person, Project, Task, Event, Document), linkin... Rather than leaving your conversation to handle this manually, you can ask your Claude agent directly — and it will take care of the task end-to-end, using ontology as its underlying capability.

ontology works across Claude, Cursor, OpenClaw through the Model Context Protocol (MCP) — an open standard that lets AI clients share tools and skills without lock-in. Because MCP is platform-agnostic by design, you install ontology once and it becomes available across all your AI clients. Whether you're working in Claude for focused sessions or Cursor for integrated workflows, the skill behaves consistently.

ontology installs like any other MCP skill: drop the folder into `~/.claude/skills/ontology/` for global access, or `.claude/skills/ontology/` to keep it scoped to one project. After a quick restart of Claude, you can trigger it explicitly with `/ontology`, or let the AI decide when it's the right tool for your request.

ontology is one of the most-installed skills on DiscoverAISkills, with over 167,031 installs — a level of adoption that reflects genuine usefulness across a wide range of workflows. Like all skills on DiscoverAISkills, it is free to install and use. The broader AI skills ecosystem continues to expand as developers contribute new capabilities across categories like developer tools, data analysis, writing, automation, and more.
