Vercel announced the Agent Plugins standard on August 6, allowing AI agent extensions to be packaged in a shared format so developers can write Agent Skills and MCP server configurations once and reuse them across multiple platforms.
ChatGPT, Codex, VS Code, Cursor, and GitHub Copilot are among the eight clients that already support it, backed by a standards body including OpenAI, Amazon, Cursor, and Microsoft—though Anthropic's Claude Code and Claude Cowork are not yet compatible.
What happened
Vercel announced the "Agent Plugins" standard on August 6, a shared format for packaging AI agent extensions. The standard lets Agent Skills (procedure files) and MCP server settings be written once and reused across multiple agents. ChatGPT, Codex, VS Code, Cursor, GitHub Copilot, and five other clients now support it; Anthropic's Claude Code and Claude Cowork do not yet.
Why it matters
A unified standard lowers friction for developers building agent extensions—they no longer need to rebuild the same functionality for each platform. The backing of OpenAI, Amazon, Cursor, and Microsoft in the standards body signals broad industry alignment, though Anthropic's absence suggests competing visions for how agents should be extended.
What to watch
Whether Anthropic adds support for Claude Code and Claude Cowork. The standard currently covers 8 compatible clients; growth in adoption will depend on how widely developers embrace the Agent Plugins format over proprietary extensions.
On August 6, Vercel unveiled Agent Plugins, a standard format for packaging extensions that AI agents use during operation. The standard allows developers to write Agent Skills—procedure files (SKILL.md) that agents reference when executing tasks—and MCP server configurations (mcp.json) in a common format, then reuse them across multiple AI agent platforms without rebuilding for each one.
The standards effort reflects a broader push toward interoperability in the AI agent space. Vercel proposed the standard and convened a technical steering committee that includes OpenAI, Amazon, Cursor, and Microsoft—all major players in developer tools and AI infrastructure. This composition suggests the standard carries weight among established platforms.
Eight clients have already adopted Agent Plugins: VS Code, Cursor, Kiro, Hermes Agent, GitHub Copilot, OpenClaw, ChatGPT, and Codex. However, Anthropic's Claude Code and Claude Cowork are not yet compatible, marking a notable gap for users of Claude-based agent workflows. The distinction suggests Anthropic may maintain its own extension or integration path, or that support may follow in a future release.
Vercel's Agent Plugins standard addresses a fragmentation problem in the emerging AI agent ecosystem. As different AI platforms and code editors each developed their own ways for agents to reference procedures and connect to external services, developers faced duplication: writing the same extension multiple times to support ChatGPT, VS Code, GitHub Copilot, and others. By proposing a shared format for Agent Skills (the instruction files agents consult at runtime) and MCP server configurations, Vercel aims to create a write-once, use-everywhere model that mirrors how web standards reduced friction across browsers.
The backing of OpenAI, Amazon, Cursor, and Microsoft suggests mainstream adoption is likely among leading platforms. However, Anthropic's absence is notable: neither Claude Code nor Claude Cowork currently supports the standard, despite Claude's prominence in the agent space. This gap may indicate a deliberate choice by Anthropic to maintain its own extension architecture, or it may be a matter of timing—adoption could still follow. The eight clients now supporting Agent Plugins represent a critical mass around which developers can build, but broader coverage (especially Anthropic) would signal a true industry consensus.
