If you build AI extensions, you know the pain of recreating the same Agent Skill or MCP server for every platform. Vercel just released Agent Plugins 1.0.0, an open standard that lets you build once and run everywhere.
Your one manifest file now works across ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code — with AWS, Microsoft, OpenAI, GitHub, and Vercel behind it.
What Happened
Agent Plugins 1.0.0 introduces a single, predictable directory structure. Instead of rewriting metadata, discovery paths, and configuration for each client, you create one manifest file and your extension becomes compatible with every platform that supports the standard.
The launch partners cover the biggest AI coding tools and assistants: ChatGPT, Codex, Cursor, GitHub Copilot, Kiro, and VS Code. The standard was built with collaboration from AWS, Microsoft, OpenAI, GitHub, and Vercel.
Why It Matters
This is a universal contract between developers and AI clients, not another walled garden. If you build AI agents, you can stop porting the same extension to every new platform. Package your code once and run it everywhere.
The future of AI development is standardized, portable, and open — and it starts with Agent Plugins 1.0.0.
