Agent Plugins - Open Standard for AI Agents
If you wanted to release your skills/MCP for a AI apps like Cursor, Codex, etc, you’ll need to publish it in the way that the apps are expecting.
There is no standard want to handle it.
That’s what Agent Plugins spec is trying to solve.
Agent Plugins is an open, vendor-neutral standard for packaging reusable components into portable plugins. Its version 1.0.0 specification defines a shared format for Agent Skills and MCP servers that compatible clients can discover and load consistently.
An Agent Plugin is a directory with a required manifest and optional components in fixed locations:
my-plugin/
├── plugin.json
├── skills/
│ └── summarize/
│ ├── SKILL.md
│ ├── scripts/
│ └── references/
├── mcp.json
└── com.example.client/
└── hooks/
As of now, it’ll be supported in these apps: ChatGPT and Codex, Cursor, GH Copilot, Kiro, VS Code.
